Dr Mahdiyeh Razeghi from the Australian National University (anu.edu.au) describes how satellites are used to accurately determine how much water there is, and where it is in the environment. This as part of a series of educational videos on our Earth's water.
This clip has been created by the Research School of Earth Sciences (rses.anu.edu.au). These resources are part of a comprehensive program, curriculum matched to the unit 'Introduction to Earth systems'.
This video touches on the following curriculum descriptors:
- The modern atmosphere has a layered structure characterised by changes in temperature: the troposphere, mesosphere, stratosphere and thermosphere (ACSES022)
- Water’s unique properties, including its boiling point, density in solid and liquid phase, surface tension and its ability to act a solvent, and its abundance at the surface of Earth make it an important component of Earth system processes (for example, precipitation, ice sheet formation, evapotranspiration, solution of salts) (ACSES024)

In the previous video (https://youtu.be/_1NPHxCQT3Q) we saw how we can find whether the decimal expansion of any given rational number is terminating or non-terminating and recurring (repeating) without actual division. In this video, let's see why do we need 2s and 5s to check whether the decimal expansion of the given rational number is terminating or non-terminating and recurring.

American History: From Emancipation to the Present (AFAM 162)
Between 1865 and 1877, several plans were developed by which the Confederate states could be readmitted to the Union and the residents of the states given full citizenship rights. It was far from clear, however, which plan would do a better job maintaining the social peace and protecting African Americans' ability to earn a wage, raise a family, own land, and exercise the right to vote. In this lecture, Professor Holloway outlines the contours of the Ten Percent Plan, Presidential Reconstruction, and Radical Reconstruction, and he explains how these plans embraced a variety of approaches to reuniting the disparate states. As Professor Holloway explains, Reconstruction greatly enhanced the rights of African Americans, while also circumscribing their lives by new political, economic, and social initiatives.

The number of people forced to flee their homes has increased every year over the past decade and now stands at the highest level since records began.
We predicted in last year’s Global Trends Report that the question was no longer if forced displacement will exceed 100 million people – but rather when. The when is now.
Visit unhcr.org to see how you can help get involved.

this academic video for Advanced level students taking chemistry for UACE exams; it describes equilibrium constant Kc and its application with several worked examples.
In chemistry, equilibrium refers to a state where the rates of the forward and reverse reactions of a chemical reaction are equal. This means that the concentration of reactants and products remain constant over time, even though the reactions continue to occur. At equilibrium, the system is said to be in a dynamic balance.
The equilibrium constant, denoted by Kc, is a numerical value that represents the ratio of the concentrations of products to the concentrations of reactants, with each concentration raised to the power of its stoichiometric coefficient in the balanced chemical equation. The equilibrium constant expression is written as:
Kc = [C]^c [D]^d / [A]^a [B]^b
Where A, B, C, and D represent the reactants and products, and a, b, c, and d represent their stoichiometric coefficients.
The equilibrium constant is a measure of the extent to which a reaction proceeds toward the formation of products. It is a constant at a given temperature and is independent of the initial concentrations of the reactants. The value of Kc reflects the relative concentrations of the reactants and products at equilibrium.
The magnitude of the equilibrium constant provides information about the position of equilibrium.
- If Kc > 1, it indicates that the equilibrium favors the products. This means that at equilibrium, the concentration of the products is higher compared to the concentrations of the reactants.
- If Kc < 1, it suggests that the equilibrium favors the reactants. At equilibrium, the concentration of the reactants is higher compared to the concentrations of the products.
- If Kc = 1, it signifies that the reactants and products are present in roughly equal concentrations at equilibrium.
The equilibrium constant provides insights into the direction in which a reaction will proceed or which species will be present in greater abundance at equilibrium. It also allows for predictions about the effect of changes in concentration, temperature, or pressure on the position of equilibrium.

definition of prokaryotic and eukaryotic cell. differences between prokaryotic and eukaryotic cells
Prokaryotic and eukaryotic cells are two types of cells that make up all living organisms. They differ in their structural complexity and organization.
1. Structure:
- Prokaryotic cells: Prokaryotic cells are generally smaller and simpler in structure compared to eukaryotic cells. They lack a nucleus and membrane-bound organelles. Instead, their DNA is present in a region called the nucleoid, and they have few internal structures called ribosomes.
- Eukaryotic cells: Eukaryotic cells are larger and more complex. They contain a well-defined nucleus that houses the DNA. In addition, eukaryotic cells possess various membrane-bound organelles, such as mitochondria, endoplasmic reticulum, golgi apparatus, and others.
2. DNA Organization:
- Prokaryotic cells: Prokaryotes have a single, circular DNA molecule floating freely in the cytoplasm. It lacks the organization into chromosomes seen in eukaryotic cells.
- Eukaryotic cells: Eukaryotes have linear DNA molecules that are organized into multiple chromosomes, typically found within the nucleus.
3. Membrane-bound Organelles:
- Prokaryotic cells: Prokaryotes lack membrane-bound organelles. They have some specialized regions within their cytoplasm, such as ribosomes for protein synthesis, but these structures are not surrounded by membranes.
- Eukaryotic cells: Eukaryotes possess membrane-bound organelles that perform specific functions. These include the nucleus (DNA storage and transcription), mitochondria (energy production via cellular respiration), endoplasmic reticulum (protein synthesis and lipid metabolism), and golgi apparatus (modifying, sorting, and packaging proteins).
4. Complexity:
- Prokaryotic cells: Prokaryotes are simpler in structure and organization, lacking compartmentalization. They can be found as unicellular organisms, such as bacteria and archaea.
- Eukaryotic cells: Eukaryotes are more complex, with compartmentalization provided by membrane-bound organelles. They can be found as both unicellular (e.g., yeast) and multicellular organisms (e.g., plants, animals, fungi).
In summary, prokaryotic cells are smaller, simpler, lack a nucleus, and lack membrane-bound organelles. Eukaryotic cells are larger, more complex, contain a nucleus, and possess membrane-bound organelles.

Well discussed structured questions from national exams
Types of skeleton, locomotion in earthworm, locomotion in insects, human skeleton, function of bones, types of muscles and their differences and joints.
Locomotion is the ability of living organisms to move around from one place to another. Animals have developed different mechanisms and body structures to enable them to move in different environments.
Vertebrates, or animals with backbones, employ various methods of locomotion. Birds and bats, for example, have wings that enable them to fly, while fish have fins and tails that help them swim. Mammals, including humans, have legs that allow them to walk, run, or climb. Other animals like snakes use their body muscles to crawl or slither.
Invertebrates, or animals without backbones, use a variety of methods to move. Jellyfish and sea anemones contract and expand their muscles to propel themselves through the water. Insects and spiders have multiple legs that enable them to walk, run, or jump.
Some animals have specific adaptations that allow them to move in extreme environments. For example, polar bears have large, webbed paws that help them walk on ice. Kangaroos use their powerful hind legs to hop across vast distances in the Australian outback.
Overall, locomotion is essential for animals to find food, escape predators, and navigate their environments.

structure, adaptations and functions of photosynthesis, chemistry of photosynthesis(light harvesting, electron transport and Calvin cycle), C3 and C4 plants, advantages of C4 plants over C3 plant, differences between respiration and photosynthesis.
Structure and Adaptations of Photosynthesis:
- Photosynthesis occurs in the chloroplasts of plant cells.
- Chloroplasts contain a green pigment called chlorophyll, which captures sunlight.
- The chloroplasts have an inner membrane, outer membrane, and thylakoid membranes, where the various stages of photosynthesis take place.
- The thylakoid membranes are arranged in stacks called grana, and the fluid-filled space surrounding the grana is called the stroma.
- Adaptations of photosynthesis include the presence of large surface areas with abundant chloroplasts in leaves, and the arrangement of chlorophyll molecules in the thylakoid membranes to maximize light absorption.
Functions of Photosynthesis:
- Conversion of sunlight energy into chemical energy in the form of glucose.
- Production of oxygen as a byproduct, which is released into the atmosphere.
- Biosynthesis of carbohydrates and other organic compounds necessary for the plant's growth and maintenance.
Chemistry of Photosynthesis:
1. Light Harvesting: Chlorophyll absorbs photons of light energy, exciting electrons and initiating the process.
2. Electron Transport: Excited electrons are passed through a series of electron carriers within the thylakoid membranes, generating ATP and reducing NADP+ to NADPH.
3. Calvin Cycle: This occurs in the stroma and involves a series of enzyme-mediated reactions that use ATP and NADPH to convert carbon dioxide into glucose.
C3 and C4 Plants:
- C3 plants: Common plants like wheat, rice, and oats that directly use the C3 pathway in photosynthesis. In this pathway, carbon dioxide is initially fixed into a three-carbon compound.
- C4 plants: Plants like corn, sugarcane, and sorghum that have an additional step before entering the C3 pathway. They first fix carbon dioxide into a four-carbon compound, helping them adapt to hotter and drier environments.
Advantages of C4 Plants over C3 Plants:
- C4 plants have a higher rate of photosynthesis and can better withstand high temperatures and low carbon dioxide conditions.
- Their unique carbon fixation process allows them to efficiently use water and nutrients, promoting their growth in arid conditions.
- C4 plants often exhibit better water use efficiency compared to C3 plants.
Differences between Respiration and Photosynthesis:
1. Respiration occurs in all living cells, while photosynthesis occurs only in plants, algae, and some bacteria.
2. Respiration involves the breakdown of glucose to produce ATP, releasing carbon dioxide as a byproduct, while photosynthesis fixes carbon dioxide to produce glucose, releasing oxygen as a byproduct.
3. Respiration occurs continuously, while photosynthesis typically occurs during daylight hours.
4. Respiration releases energy, while photosynthesis stores energy.
Production and transmission of sound waves, experiment to show that transmission of sound waves requires material medium, factors affecting speed of sound waves, Quality of sound i.e. pitch, loudness and timbre
Sound waves are mechanical waves that propagate through a medium by compressing and rarefying the particles of the medium. They are created by the vibration of an object or source, which causes particles in the medium to vibrate and transfer energy.
Key characteristics of sound waves include:
1. Frequency: The frequency of a sound wave refers to the number of cycles or vibrations it completes in one second. It is measured in Hertz (Hz). Higher frequencies result in higher-pitched sounds, while lower frequencies produce lower-pitched sounds.
2. Amplitude: The amplitude of a sound wave represents the maximum displacement of the particles in the medium from their resting position. It determines the loudness or intensity of a sound. Greater amplitude results in a louder sound, while smaller amplitude produces a softer sound.
3. Wavelength: The wavelength of a sound wave is the distance between two consecutive compressions or rarefactions of the wave. It is inversely proportional to the frequency of the wave. Longer wavelengths correspond to lower frequencies, while shorter wavelengths correspond to higher frequencies.
4. Speed: The speed of sound refers to the rate at which sound waves travel through a medium. It depends on the properties of the medium, such as temperature, density, and elasticity. In dry air at room temperature, sound travels at approximately 343 meters per second.
Sound waves can be transmitted through different mediums, including air, water, and solids. They propagate in all directions and can be reflected, refracted, diffracted, and absorbed by various objects and surfaces they encounter.
Sound waves are responsible for our perception of sound and have numerous applications, including:
1. Communication: Sound waves enable us to communicate through speech, music, and other forms of audio transmission.
2. Music: Sound waves are the basis of music, allowing us to enjoy melodies, harmonies, and rhythms.
3. Sonar: Sound waves are used in sonar systems for navigation and underwater detection by emitting sound and analyzing its reflection.
4. Medical Imaging: Techniques like ultrasound employ sound waves to create images of internal organs and tissues in medical diagnosis and monitoring.
5. Noise cancellation: Sound waves can be manipulated to cancel or reduce unwanted sounds in noise cancellation technology.
By understanding the properties, behaviors, and applications of sound waves, we gain insights into the phenomena and principles underlying our auditory experiences and the practical use of sound in various domains.

The molar conductivity of electrolytes is influenced by the concentration of the solution. Here are some key points to understand the effect of concentration on molar conductivity:
1. Generally, the molar conductivity of an electrolyte decreases as the concentration increases.
2. This behavior is explained by the phenomenon of ion-ion interactions or the association of ions when the concentration increases.
3. Initially, at low concentrations, the ions are far apart from each other, resulting in minimal ion-ion interactions. This allows for higher mobility of the ions and a higher molar conductivity.
4. As the concentration increases, the ions come closer to each other, leading to a greater likelihood of ion-ion interactions or association. This hinders the mobility of the ions, reducing the molar conductivity.
5. At higher concentrations, the molar conductivity approaches a limiting value called the limiting molar conductivity (Λ°). This value represents the maximum molar conductivity attainable for the electrolyte under the given conditions.
6. The decrease in molar conductivity with increasing concentration can be described by Kohlrausch's law, which states that the molar conductivity of an electrolyte is the sum of the contributions of the individual ions in the solution.
7. In dilute solutions, where ion-ion interactions are minimal, the molar conductivity is mainly determined by the individual ion mobilities. As the concentration increases, the contributions from individual ion mobilities decrease due to increased ion-ion interactions.
8. Strong electrolytes, which undergo complete ionization in solution, show a more pronounced decrease in molar conductivity with increasing concentration compared to weak electrolytes.
In summary, as the concentration of an electrolyte increases, the molar conductivity tends to decrease due to increased ion-ion interactions or association. However, at very low concentrations, the molar conductivity is higher, indicating greater ion mobility.

## Principles of Electrolysis: Selective Discharge of Ions
Electrolysis involves the use of electrical energy to drive a non-spontaneous chemical reaction. During this process, an electric current flows through an **electrolyte** (a solution containing ions) and causes the ions within to migrate towards the electrodes. However, not all ions are created equal!
The concept of **selective discharge of ions** is crucial in understanding how electrolysis works. It refers to the phenomenon where **only certain ions are discharged** (gain or lose electrons) at the electrodes, while others remain in the solution un-reacted.
Here are the key factors influencing which ions get discharged:
**1. Reactivity Series:**
- Metals higher in the reactivity series are **more easily oxidized** (lose electrons) and therefore **less likely to be discharged** at the cathode. (e.g., Sodium, Potassium)
- Conversely, metals **lower in the series** are **more difficult to oxidize** and are **more likely to be discharged** at the cathode. (e.g., Copper, Silver)
**2. Ion Concentration:**
- Ions present in **higher concentrations** are **more likely to be discharged** than those present in lower concentrations. This is simply due to the increased number of collisions between the ions and the electrode.
**3. Electrode Material:**
- The material of the electrode can also play a selective role. Some electrodes have a **higher affinity for specific ions** compared to others.
**Overall process:**
1. **Cations (positive ions)** are attracted to the **cathode (negative electrode)**, where they **gain electrons and are reduced**.
2. **Anions (negative ions)** are attracted to the **anode (positive electrode)**, where they **lose electrons and are oxidized**.
The specific reactions at the electrodes depend on the specific electrolyte and electrode materials used. However, the **selective discharge of ions** remains the fundamental principle governing which ions react and how.

Electrolysis is a process that uses an electric current to drive a non-spontaneous chemical reaction. It involves the splitting of a compound into its individual elements or ions using electricity.
The process of electrolysis takes place in an electrolytic cell, which consists of two electrodes - an anode and a cathode - immersed in an electrolyte solution. The anode is positively charged and the cathode is negatively charged. When an electric current is passed through the electrolyte, positive ions migrate towards the cathode, while negative ions migrate towards the anode.
At the anode, oxidation occurs, causing the anode to lose electrons and become positively charged. This creates a flow of electrons through the external circuit, allowing the current to continue flowing. At the cathode, reduction occurs, causing the cathode to gain electrons and become negatively charged.
The electrolysis process can be used for various purposes, including extraction of metals from their ores, electroplating, and electrolysis of water to produce hydrogen and oxygen gas.
Electrolysis is governed by Faraday's laws, which state that the amount of substance produced or consumed during electrolysis is proportional to the quantity of electricity passed through the cell. This allows for precise control and measurement of the products formed during electrolysis.
Overall, electrolysis is an important process in various industries, providing a means for generating new chemical substances and extracting valuable materials from compounds. It plays a crucial role in areas such as metallurgy, chemistry, and energy production.
Electrolytic cells are devices that use an electric current to drive a non-spontaneous chemical reaction, known as electrolysis. They consist of an anode, a cathode, an electrolyte, and an external power source.
- Anode: The electrode connected to the positive terminal of the power source. It carries out the oxidation half-reaction by losing electrons.
- Cathode: The electrode connected to the negative terminal of the power source. It carries out the reduction half-reaction by gaining electrons.
- Electrode: Conductive surfaces where the redox reactions occur. The anode and cathode are typically made of inert materials such as platinum or graphite.
- Electrolyte: A solution or molten substance that contains ions and allows the flow of electricity. Common examples include aqueous solutions of salts or acids.
- Electric Current: The flow of charged particles (ions or electrons) through a conductor. In electrolytic cells, the power source provides the necessary electrical energy for the movement of ions.
During electrolysis, the anode attracts negatively charged ions from the electrolyte and oxidizes them. This generates electrons that flow through the external circuit to the cathode. At the cathode, positively charged ions from the electrolyte are attracted, and reduction occurs as they gain electrons.
The overall process of electrolysis involves the decomposition of the electrolyte into its constituent ions. For example, in the electrolysis of water, water molecules (H2O) are split into hydrogen ions (H+) at the cathode and oxygen gas (O2) at the anode.
Electrolytic cells have various applications, including electroplating, metal refining, electrorefining, production of chemicals, and water splitting for hydrogen production.
To distinguish between weak, strong, and non-electrolytes, you can perform an experiment known as the light bulb conductivity test. This experiment uses the ability of electrolytes to conduct electricity and complete a circuit, causing a light bulb to light up. Here's how to carry out this experiment:
Materials needed:
1. Light bulb
2. Battery or power source (of appropriate voltage for the light bulb)
3. Wires with alligator clips or connectors
4. Solutions of known weak electrolytes (e.g., acetic acid or vinegar)
5. Solutions of known strong electrolytes (e.g., sodium chloride or table salt)
6. Solutions of known non-electrolytes (e.g., sugar or ethanol)
7. Conductivity tester or conductivity meter (optional)
8. Glass containers or beakers
9. Disposable pipettes or droppers
Procedure:
1. Set up the circuit by connecting the positive terminal of the battery to the bottom terminal of the light bulb using a wire with an alligator clip or connector.
2. Connect the top terminal of the light bulb to one end of another wire.
3. Fill separate glass containers or beakers with solutions of the known weak electrolyte, known strong electrolyte, and known non-electrolyte.
4. Label each container with the corresponding solution.
5. Dip the free end of the wire from step 2 into one of the solutions.
6. Observe if the light bulb lights up or not.
7. Repeat steps 5-6 for each solution, noting whether the light bulb lights up or not.
Results and Interpretation:
- Weak electrolyte solution: If the light bulb glows dimly or flickers, it indicates that the weak electrolyte solution allows some conductivity and completes the circuit, but not as effectively as a strong electrolyte.
- Strong electrolyte solution: If the light bulb lights up brightly and stays consistently lit, it suggests that the strong electrolyte solution conducts electricity well and completes the circuit effectively.
- Non-electrolyte solution: If the light bulb does not light up at all, it suggests that the non-electrolyte solution does not allow any significant conductivity and does not complete the circuit.
By observing the behavior of the light bulb in each solution, you can distinguish weak, strong, and non-electrolytes based on their ability to conduct electricity and complete the circuit.
One experiment that demonstrates the migration of ions during electrolysis is the electrolysis of water using a solution of sodium sulfate (Na2SO4). This experiment showcases the migration of both positively and negatively charged ions.
Materials:
1. 9-volt battery or a power source
2. Two graphite electrodes (pencil leads or graphite rods)
3. Sodium sulfate solution (Na2SO4)
4. Two wires with alligator clips
5. Beaker
6. Voltmeter (optional)
Procedure:
1. Fill a beaker with the sodium sulfate solution, ensuring that it covers the graphite electrodes completely.
2. Connect one graphite electrode to the positive terminal of the battery using a wire with an alligator clip.
3. Connect the other graphite electrode to the negative terminal of the battery using another wire with an alligator clip.
4. Immerse both graphite electrodes into the sodium sulfate solution, making sure that they do not touch each other.
5. Turn on the power source (battery) and allow the electrolysis process to occur for a few minutes.
Observations:
1. Bubbles start forming around both electrodes, indicating the release of gases.
- Oxygen gas (O2) will be produced at the positive electrode (anode).
- Hydrogen gas (H2) will be produced at the negative electrode (cathode).
Explanation:
During the electrolysis of water using the sodium sulfate solution, the following reactions occur at the electrodes:
At the anode (positive electrode):
2H2O(l) → O2(g) + 4H+(aq) + 4e-
Water molecules break down, producing oxygen gas, positively charged hydrogen ions (H+), and releasing electrons.
At the cathode (negative electrode):
4H+(aq) + 4e- → 2H2(g)
The positively charged hydrogen ions (H+) from the water are reduced, accepting electrons to form hydrogen gas (H2).
This experiment clearly demonstrates the migration of ions in the solution. The positively charged hydrogen ions (H+) migrate towards the cathode, where they are reduced to form hydrogen gas. Conversely, the negatively charged sulfate ions (SO4 2-) remain in the solution as sodium sulfate is a neutral salt.
By observing the gases generated at each electrode, you can visualize and verify the migration of ions during electrolysis. Remember to exercise caution and perform this experiment under adult supervision, as electrolysis involves the use of electricity.

A titration pH curve is a graphical representation of how the pH of a solution changes as a titration progresses. It typically exhibits several distinct features that can provide valuable information about the reaction being studied. The main features of a titration pH curve are:
1. Initial pH: At the start of the titration, before any titrant has been added, the initial pH is determined by the solution being titrated. For example, if an acidic solution is being titrated against a basic titrant, the initial pH will be low (acidic).
2. Slow pH change: Initially, as the titrant is added slowly, the change in pH is relatively slow because the reaction between the titrant and analyte is not yet significant enough to alter the pH dramatically. This region is often referred to as the buffering region, as the solution's pH remains relatively stable.
3. Equivalence point: The equivalence point is the point at which the stoichiometrically equivalent amounts of acid and base have reacted. At this point, the pH undergoes a rapid change. For the reaction between a strong acid and a strong base, the equivalence point occurs at pH 7, indicating a neutral solution.
4. Midpoint of the buffering region: Before reaching the equivalence point, there is a point where the pH undergoes the steepest slope, known as the midpoint of the buffering region. This point corresponds to approximately halfway between the initial pH and the pH at the equivalence point. It is an important reference point as it helps determine the pH range over which the buffer works effectively.
5. Endpoint: The endpoint is the point at which the indicator used in the titration changes color, indicating that the reaction is approaching completion. Ideally, the endpoint should coincide with the equivalence point, but in practice, slight differences may occur.
6. Post-equivalence region: After passing the equivalence point, the pH continues to change, but at a slower rate compared to the pre-equivalence region. In the case of titrating a strong acid with a strong base or vice versa, the pH in this region approaches the pH of the excess titrant. Thus, if a strong acid is being titrated with a strong base, the pH will increase above 7. The shape and steepness of this region depend on the nature and concentration of the titrant and analyte.
These features collectively provide insight into the behavior of the titration, helping determine the equivalence point, the stoichiometry of the reaction, the strength of the acid or base, and the buffering capacity of the solution. Analyzing the pH curve allows for the proper interpretation of the experimental data obtained during titration.
Completely soluble salts are those that dissolve entirely in water to form a homogeneous solution. The solubility of these salts in water depends on various factors such as temperature, pressure, and the nature of the salt and solvent.
There are some general rules for predicting the solubility of ionic compounds in water. These rules are based on the principle that “like dissolves like,” where polar substances dissolve in polar solvents, and nonpolar substances dissolve in nonpolar solvents.
1. Salts containing group 1 cations (Li+, Na+, K+, Rb+, and Cs+) are completely soluble in water.
2. Salts containing the ammonium ion (NH4+) are completely soluble in water.
3. Salts containing the nitrate ion (NO3-) are completely soluble in water.
4. Salts containing the chloride ion (Cl-) are mostly soluble in water. However, some chloride salts of less electronegative metals such as AgCl and PbCl2 are insoluble.
5. Salts containing the sulfate ion (SO42-) are mostly soluble in water. However, some sulfate salts of less electronegative metals such as BaSO4 and PbSO4 are insoluble.
6. Salts containing the carbonate ion (CO32-) and the phosphate ion (PO43-) are mostly insoluble in water. However, some of their soluble salts, such as Na2CO3 and Na3PO4, are completely soluble.
These rules are useful in predicting the solubility of completely soluble salts in water and can help in identifying insoluble salts. Keep in mind that these rules are not absolute, and some exceptions to them can occur.
Antiderivatives or indefinite integrals are the first introduction to integral calculus. Now that your teacher has taught you calculus, you get to do it all backwards! Don't forget PLUS C
Using the chain rule we show how to integrate backwards. So much fun!
It's actually a lot easier than you think, especially if you take a deep breath and relax before you begin.
Some teachers teach decomposition for factoring trinomials, my method is the EASIEST way to factor a "complex" trinomial. Making the complex simple is my motto!

Welcome to Grade 10 mathematics. In this course you will learn many new concepts including quadratics and trigonometry. This course is a very important foundation for everything you will do in grade 11 and 12. In this lesson I review some vocabulary from grade 9, show three different graphing techniques for lines including table of values, x and y intercepts and slope and y-intercepts. Finally we will rearrange from standard to slope y-intercept form and vice versa.
What does solving a linear system mean? How do we find the solution to a linear system by graphing? In this lesson I will solve some basic linear equations by graphing and then will solve a word problem involving mixtures and one using distance speed and time using graphing skills.
A little bit trickier questions using elimination with decimals and fractions.
What you need to do is to multiply by a factor of 10 to first clear the decimals, so if you have 0.1x multiply by 10; if you had 0.01x multiply by 100. Remember to multiply each and every term in the equation.
For fractions you need to multiply by the lowest common denominator to clear the fractions.
In this video I do several examples of each so you will be all set to conquer any system of equations that comes your way!
Le Chatelier's Principle is a fundamental concept in chemistry that explains how systems at equilibrium respond to changes in conditions. According to this principle, when a system at equilibrium is subjected to an external influence, it will adjust in such a way as to counteract the change and reestablish equilibrium.
Adding a catalyst to a reaction is one such external influence. However, unlike changes in temperature, pressure, or concentrations, adding a catalyst does not directly affect the position of the equilibrium or alter the concentrations of reactants or products. Instead, a catalyst provides an alternative pathway for the reaction to occur, lowering the activation energy barrier. This allows the reaction to proceed at a faster rate without being consumed itself.
In the context of Le Chatelier's Principle, adding a catalyst to a reaction at equilibrium does not cause any immediate response. The equilibrium composition and concentrations of reactants and products remain unaffected. However, the presence of a catalyst can increase the rate at which the reaction reaches equilibrium.
It's important to note that catalysts do not shift the equilibrium position or favor the formation of products or reactants. They only enhance the rate at which the equilibrium is reached by providing an alternative reaction pathway with lower activation energy. Once equilibrium is attained, the catalyst does not affect the equilibrium concentrations.
On Khan Academy, you can find more detailed explanations and examples of Le Chatelier's Principle, as well as related topics in equilibrium chemistry. Their resources, including videos, articles, and practice exercises, can help you fully understand the principles and applications of equilibrium reactions in chemistry.
Enjoy your learning and exploration of this fascinating field!
To identify the best oxidizing agent using Eo(red.) values, you need to compare the Eo(red.) values of the potential oxidizing agents. The species with the higher Eo(red.) value will be the stronger oxidizing agent.
Here are some general rules for comparing Eo(red.) values:
1. The species with the higher Eo(red.) value will be more likely to undergo reduction and, therefore, act as the oxidizing agent.
2. The species with the lower Eo(red.) value will be more likely to undergo oxidation and, therefore, act as the reducing agent.
3. The larger the difference in Eo(red.) values between two species, the stronger the oxidizing agent and the weaker the reducing agent.
For example, consider the following half-reactions:
Half-reaction 1: A+ + e- --> A (Eo(red.) = 0.8 V)
Half-reaction 2: B2+ + 2e- --> 2B+ (Eo(red.) = 1.5 V)
In this case, half-reaction 2 has the higher Eo(red.) value (1.5 V) compared to half-reaction 1 (0.8 V). Therefore, B2+ is the stronger oxidizing agent.
It is important to note that Eo(red.) values can only be compared within the same system, meaning you cannot directly compare Eo(red.) values from different reference electrodes or different systems. Additionally, other factors such as concentration and temperature can also influence the oxidizing strength of a species, so it is important to consider these variables as well.

Reaction Rates:
Reaction rate is a measure of how fast a chemical reaction takes place. It is often described as the change in concentration of a reactant or product per unit of time. The rate of a chemical reaction is influenced by several factors, including temperature, concentration of reactants, surface area, and the presence of catalysts.
Temperature: Increasing the temperature generally increases the reaction rate. This is because higher temperatures provide more energy to the reactant particles, causing them to move faster and collide with greater force. This leads to a higher frequency of effective collisions, resulting in a faster reaction rate.
Concentration: Increasing the concentration of reactants typically increases the reaction rate. This is because a higher concentration means there are more reactant particles present, leading to a higher frequency of collisions and a greater likelihood of effective collisions.
Surface Area: Increasing the surface area of solid reactants can increase the reaction rate. This is because greater surface area provides more opportunities for reactant particles to come into contact with each other, increasing the frequency of collisions.
Catalysts: Catalysts are substances that increase the reaction rate by providing an alternative pathway for the reaction with lower activation energy. They do not get consumed in the reaction and can be reused. Catalysts work by reducing the energy barrier required for the reaction to occur, allowing more reactant particles to overcome this barrier and participate in the reaction.
Reversible Reactions:
Reversible reactions are chemical reactions that can proceed in both the forward and reverse directions. This means that reactants can form products, and products can also react to form the original reactants. Reversible reactions are often represented by a double-headed arrow, indicating that the reaction can occur in both directions.
An example of a reversible reaction is the formation of water from hydrogen and oxygen:
2H2 + O2 ⇌ 2H2O
In this reaction, hydrogen and oxygen can react to form water, and water can also decompose to form hydrogen and oxygen. The double-headed arrow represents the equilibrium between the forward and reverse reactions.
In a reversible reaction, the reaction rate of the forward and reverse reactions can be different. The extent to which a reversible reaction proceeds in the forward direction depends on the relative concentrations of reactants and products. At equilibrium, the reaction rates of the forward and reverse reactions become equal, and there is no net change in the concentrations of reactants and products.
Factors such as temperature, pressure, and concentration can affect the position of equilibrium in a reversible reaction. These factors can shift the equilibrium towards the formation of more products or reactants.

Have you ever wondered whether you need to be good at math to become a developer? Well in this video we explain it all.
Developers don’t need to prove theorems or solve differential equations, but they need to understand coordinate systems, they need to know what a function is, they should be able to perform simple calculations, and they should have well-developed algorithmic thinking, which is like the logical thinking used in math.

Lesson 6 :The Solid State Part - 03 (Packing Efficiency,Classification of Solids Based on Their..)
Many times in this journey of life we face challenges that seem so huge and insurmountable.
There are times when you hit the wall and you can't see anything ahead but darkness. There are times when the enemy speaks with a very frightening voice and you feel like giving up. BUT ALWAYS REMEMBER THIS- there is a God who fights battles for those who trust in Him. That God who stood by David in the face of Goliath, the mighty giant!
May this song encourage all of us NEVER TO LOSE HOPE even in the hardest of times. I have seen that God turn the darkest of situations into the brightest of days.
To you all friends who feel like giving up on account of whatever situation you're facing, I dedicate this song. Rise up. Stand up. Move ahead. #OSOBOLA

![1.3 Limits that Fail to Exist [01] - |x|/x](https://i.ytimg.com/vi/fU7JNYBxiaY/maxresdefault.jpg)
http://www.rootmath.org
http://www.rootmath.org/calculus/limits-that-fail-to-exist
Some limits don't exist. The absolute value of x over x, |x|/x, has no limit as x approaches 0. This is because there is a jump in the graph at zero, or a jump discontinuity. This causes the value of the function to differ at the two sides of the jump and so the limit fails to exist.
![1.3 Limit that Fails to Exist [02] - 1/x^2](https://i.ytimg.com/vi/DGnR49P-xf0/maxresdefault.jpg)
http://www.rootmath.org
http://www.rootmath.org/calculus/limits-that-fail-to-exist
A limit does not exist when it 'grows without bound.' Intuitively, if a function keeps getting bigger as you approach the limit value then the limit does not exist.
http://www.rootmath.org | Calculus
We look at the square root of x and find the slope of the tangent line when x is one. This is another example of finding the slope of a tangent line using the definition of the derivative.
http://www.rootmath.org | Calculus
This is the third example where will will use the definition to take the derivative of a function. More importantly we will explore the relationship between a function and it's derivative. It is essential that you understand this relationship!
http://www.rootmath.org | calculus 1
Power Rule- the easiest thing since counting
http://www.rootmath.org | Calculus 1
The derivative of all 6 trig functions.
http://www.rootmath.org | Calculus
This is our third example of using u-substitution to solve an integral. In this example we learn how to adjust for a constant
http://www.rootmath.org | Calculus
In this example we use u-substitution to find an integral involving sin and cos.
http://www.rootmath.org | Calculus
In this video we use a u-sub and the natural log rule to integrate tanx.

Electroconductivity, in the context of A-Level studies, refers to the ability of a substance or solution to conduct electricity. Here are some key points about electroconductivity at the A-Level:
1. Electrical Conductivity: Electrical conductivity is a measure of how well a substance allows the flow of electric current through it. Materials or solutions that are good conductors have high electrical conductivity, while those that impede the flow of current have low electrical conductivity.
2. Conductivity and Ions: The ability of a substance to conduct electricity is directly related to the presence of mobile charge carriers. In the case of solutions, the presence of ions in solution allows the solution to conduct electricity. In solid conductors, delocalized electrons enable the flow of current.
3. Electrolytes: Substances that readily form ions in solution are called electrolytes. Electrolytes can be strong or weak depending on their ability to ionize completely or partially. Strong electrolytes, such as strong acids or salts, produce a high concentration of ions and thus have high electrical conductivity. Weak electrolytes, on the other hand, produce a lower concentration of ions and have lower electrical conductivity.
4. Ionic Solutions: Ionic solutions, which contain ions in solution, exhibit higher electrical conductivity compared to non-ionic solutions. This is because ions act as charge carriers and facilitate the flow of current.
5. Ionic Compound Dissociation: When an ionic compound dissolves in water, it dissociates into its constituent ions. The dissociation of the compound into ions increases electrical conductivity, as the resulting solution contains mobile ions.
6. Conductivity Measurements: The electrical conductivity of a solution is typically measured using a conductivity meter. This device measures the ability of a solution to conduct an electric current and provides a numerical value for the conductivity.
7. Factors Affecting Conductivity: The electrical conductivity of a solution is influenced by several factors. Temperature, concentration of ions, and the presence of impurities can all affect the conductivity of a solution.
8. Applications: Understanding electroconductivity is important in various applications, such as in the design and operation of electrochemical cells, batteries, circuitry, and conductivity-based sensors. It is also relevant in fields like environmental science, where water quality is assessed based on its electrical conductivity.
These points provide a basic overview of electroconductivity at the A-Level. Further exploration of the topic can involve studying conductivity measurements, conductivity trends across the periodic table, and the relationship between conductivity and electrolysis or galvanic cells.u

Faraday's laws of electrolysis provide a framework for quantitative calculations involving the amount of electricity and the mass of substances deposited or liberated during electrolysis.
Here are the two main laws and some examples of calculations you can perform:
**Faraday's First Law:**
This law states that the **mass (m)** of a substance deposited or liberated at an electrode is **directly proportional** to the **amount of charge (Q)** passed through the electrolyte. Mathematically, it can be expressed as:
```
m ∝ Q
```
where the symbol "∝" represents proportionality.
**Example 1:**
* You electrolyze copper sulfate (CuSO4) solution for 30 minutes with a current of 2 amps.
* You need to calculate the mass of copper deposited at the cathode.
**Steps:**
1. **Convert time to seconds:** 30 minutes * 60 seconds/minute = 1800 seconds.
2. **Calculate the total charge:** Q = I * t = 2 A * 1800 s = 3600 C.
3. **Look up the electrochemical equivalent (ECE) of copper:** This value is typically found in chemistry handbooks or online resources. Let's assume the ECE of copper is 0.0329 mg/C.
4. **Calculate the mass of copper deposited:** m = Q * ECE = 3600 C * 0.0329 mg/C = 118.44 mg.
**Faraday's Second Law:**
This law states that the **masses of different ions liberated at the electrodes** when the **same amount of electricity (Q)** is passed through **different electrolytes** are **directly proportional to their chemical equivalents (CE)**. Mathematically, it can be expressed as:
```
m1 / m2 = CE1 / CE2
```
where:
* m1 and m2 are the masses of the deposited/liberated substances
* CE1 and CE2 are their respective chemical equivalents
**Example 2:**
* You electrolyze silver nitrate (AgNO3) and copper sulfate (CuSO4) solutions simultaneously with the same amount of charge (Q).
* You need to determine the ratio of the masses of silver and copper deposited.
**Steps:**
1. **Look up the chemical equivalents of silver and copper:** Let's assume the CE of silver (Ag) is 107.87 g/eq and the CE of copper (Cu) is 31.78 g/eq.
2. **Apply the second law equation:** m_Ag / m_Cu = CE_Ag / CE_Cu = 107.87 g/eq / 31.78 g/eq ≈ 3.4.
Therefore, the mass of silver deposited will be approximately 3.4 times the mass of copper deposited under the same conditions.
These are just two examples of calculations involving Faraday's laws. Remember, you'll need additional information like current, time, electrochemical equivalents, and chemical equivalents to perform these calculations effectively.
Factors affecting the electrolytic conductivity of electrolytes include:
1. Concentration: The concentration of the electrolyte affects conductivity. Higher concentrations result in more ions available for conduction, thus increasing conductivity.
2. Nature of Electrolyte: Different electrolytes have varying conductivities. Strong electrolytes, such as strong acids or bases, dissociate fully into ions and tend to have higher conductivity compared to weak electrolytes.
3. Temperature: Temperature impacts the mobility of ions in solution. Generally, higher temperatures increase ionic mobility and, therefore, conductivity.
4. Solvent: The nature of the solvent also influences conductivity. Polar solvents, like water, enhance ion dissociation and promote conductivity compared to nonpolar solvents.
5. Presence of Impurities: Impurities, such as dissolved gases or other substances, can affect conductivity either positively or negatively. They can alter the movement of ions and thus impact conductivity.
6. Pressure: Pressure can influence the solubility and mobility of ions, impacting electrolyte conductivity. Higher pressure often leads to higher conductivity.
7. Electrolyte Purity: The purity of the electrolyte is vital. Impurities introduced during production or storage can interfere with conductivity.
8. Presence of Additives: Some additives can enhance or hinder conductivity. They may increase ion dissociation or introduce additional ions that influence conductivity.
It's essential to consider these factors when studying or using electrolytes for various applications, including electrochemistry, batteries, and electrolysis processes.

Again for the benefit of my ERS220 class: some tips for creation of a proper technical report in Microsoft Word.
The specific requirements of any lecturer may vary (whether they want pictures centered or left-justified for example), but the general principles remain the same, and familiarity with the software is especially important.
(The screen capture software highlighted my cursor, and added the circles when I clicked and arrows when I rolled the mouse wheel, in case anyone was wondering what that was...)
Electrolysis is a process that uses an electric current to drive a non-spontaneous chemical reaction. It involves the splitting of a compound into its individual elements or ions using electricity.
The process of electrolysis takes place in an electrolytic cell, which consists of two electrodes - an anode and a cathode - immersed in an electrolyte solution. The anode is positively charged and the cathode is negatively charged. When an electric current is passed through the electrolyte, positive ions migrate towards the cathode, while negative ions migrate towards the anode.
At the anode, oxidation occurs, causing the anode to lose electrons and become positively charged. This creates a flow of electrons through the external circuit, allowing the current to continue flowing. At the cathode, reduction occurs, causing the cathode to gain electrons and become negatively charged.
The electrolysis process can be used for various purposes, including extraction of metals from their ores, electroplating, and electrolysis of water to produce hydrogen and oxygen gas.
Electrolysis is governed by Faraday's laws, which state that the amount of substance produced or consumed during electrolysis is proportional to the quantity of electricity passed through the cell. This allows for precise control and measurement of the products formed during electrolysis.
Overall, electrolysis is an important process in various industries, providing a means for generating new chemical substances and extracting valuable materials from compounds. It plays a crucial role in areas such as metallurgy, chemistry, and energy production.
Physical equilibria refer to the state of balance or stability between two or more phases of matter. Systems, phases, and components play a crucial role in understanding and analyzing physical equilibria.
A system can refer to a collection of components that interact with each other, and physical equilibria can occur within these systems. In particular, a one-component system refers to a system containing only one substance in more than one phase. For example, a water system can be composed of water in both liquid and vapor phases. Similarly, a carbon dioxide system can consist of carbon dioxide in both liquid and gaseous phases.
Phases are the different states of matter that can coexist in a system. For example, in a water system, liquid water and water vapor can coexist in a phase equilibrium. The state of equilibrium between these two phases is referred to as the saturation point or the boiling point. Similarly, a carbon dioxide system can exhibit a phase equilibrium between carbon dioxide in a gaseous and a liquid phase.
Components refer to the individual parts that make up a larger system. In a one-component system, the component refers to the substance that exists in multiple phases. For instance, in a carbon dioxide system, the component is carbon dioxide, which can exist in both gaseous and liquid phases.
An example of physical equilibria in a one-component system is the phase transition between water in liquid and vapor states. At a particular temperature, known as the boiling point, the vapor pressure of water equals the atmospheric pressure, resulting in the formation of water vapor. Similarly, in a carbon dioxide system, at a particular temperature and pressure, the vapor pressure of carbon dioxide equals the pressure above the liquid, resulting in the formation of gaseous carbon dioxide.
In conclusion, physical equilibria in one-component systems such as water and carbon dioxide systems are critical concepts in advanced-level students' studies. Understanding the relationships between systems, phases, and components is essential for comprehending physical equilibria and their applications in various fields such as chemistry, engineering, and physics.
Proteins are broken down to peptides in stomach and duodenum after which the peptides are broken down finally to amino acids in the ileum.When amino acids are in excess the body, the body does not store them but rather breaks them down in a process called deamination which involves removal of amino group from amino acid to form ammonia.Ammonia is a toxic product especially for mammals which do not have enough water in their bodies ( unlike organisms like bony fish). Therefore mammals turn the toxic ammonia into less toxic product called urea through a series of reactions in the ornithine cycle as discussed aboveOrnithine, arspatate, arginine are all amino acids.
The ornithine cycle, also known as the urea cycle, is a metabolic pathway that takes place in the liver and other tissues. It is responsible for the synthesis of urea and the detoxification of ammonia, which is a byproduct of protein metabolism. The liver plays a crucial role in this cycle by converting ammonia into urea, which can then be excreted by the kidneys.
Deamination is another important process in protein metabolism, which involves the removal of the amine group from an amino acid. This process also generates ammonia, which can be toxic to the body if it accumulates. Once again, the liver plays a critical role in removing ammonia from the body by converting it into urea, which can be safely excreted in urine.
Overall, the liver is essential for maintaining the body's nitrogen balance and preventing accumulation of toxic ammonia. Dysfunction of the liver, such as in liver disease or damage, can result in impaired ornithine cycle and deamination, leading to harmful levels of ammonia buildup in the body.
Using a very excellent handout I look at all the possible ways that you can manipulate a quadratic function. From Standard form to Vertex form to Factored Form. How to find the y-intercepts, how to find the optimal value, and how to tell how many solutions. What each form tells you, how to graph from each form. In short a COMPLETE summary of quadratics.
Handout is here for you!

Projectile word problem examples:
1. Springboard - initial height, when he enters water, maximum height
2. Fireworks - Maximum height and when, how long above 100m
3. Football - Initial height, when it hits the ground, maximum height
4. Weightlessness simulation - max altitude and how long, when weightlessness occurs, how long does the simulation of weightlessness last
A very easy lesson where we simply change our scale from degrees to radians.
Divide your graph nicely into quarters and you're all set to go ... π/2, π, 3π/2, 2π
Basic characteristics of y = sinθ y = cosθ and y = tanθ. Explanation of where and why there are asymptotes on the tanθ graph.
y = a sin[k(x-d)] + c y = a cos[k(x-d)] + c
a gives you amplitude, c gives you the axis ! So easy to set your range knowing these two values
Period = 2π/k , d is your horizontal shift AND DON'T forget to FACTOR the k value away from the x and constant terms.
Beginning with the sine, cosine and tangent graphs we discuss how we can graph their reciprocals using our knowledge of reciprocal functions.
A VERY CAREFULLY worded straightforward and COMPLETE lesson on finding equations of trigonometric functions from word problems AND on finding a certain time when a particular height will occur.
In this video I do question 6d from page 345 which requires operations with fractions that some of you may have difficulty with. It's okay to have a panic attack when you first encounter these questions as fractions seem not to be taught very thoroughly in elementary school and then there comes a time in highschool when you don't really use them and then ... BAM ... you are expected to remember how they all work. So ... I will guide you through a complete example and help you master what is already there in your brain but which might just be a tad rusty!
In order to determine the exact value of the original function we need some initial conditions to evaluate C . I do examples of basic quadratic functions, sinusoidal equation, exponential equation, and several business examples using marginal cost and marginal profit.
More examples for you. Sunlight really does influence the color of the video!
Factoring trinomials where the coefficient is on is the best! All you need to take from this lesson is 1. Look for a common factor FIRST and FOREMOST
2. Take the product of the first and the last (the first is 1 in this lesson so that's easy, it's just the last) Remember to have the trinomial in descending order first. I go slowly over some practice on finding products and sums first so you get very comfortable with what skill you need to find these two numbers.
How can you tell if you should use the difference of squares or perfect square trinomial factoring technique? Recognizing which type of factoring to use is critical to success! Don't forget to ALWAYS look for a common factor first, because sometimes it disguises a difference of squares.
Homework page 167 and 168 There are lots more practice questions later on in this chapter as well. The more you do, the easier they get!

DID U KNOW THATUp to 60% of the human adult body is water. According to H.H. Mitchell, Journal of Biological Chemistry 158, the brain and heart are composed of 73% water, and the lungs are about 83% water.This video explains to you very well what the body does in order to ensure that water in your body is neither in excess nor inadequate.
Water regulation in the body is essential for maintaining proper cellular function, blood volume, and electrolyte balance. Several organs and hormones work together to regulate water in the body. Here are some key aspects of water regulation:
1. The hypothalamus: The hypothalamus in the brain senses changes in blood osmolality, or the concentration of particles in the blood. When the osmolality increases, the hypothalamus stimulates the release of antidiuretic hormone (ADH) from the pituitary gland.
2. ADH: ADH, also known as vasopressin, is a hormone that regulates water reabsorption in the kidneys. ADH acts on the kidneys to increase the reabsorption of water, leading to decreased urine output and increased water retention. When blood osmolality decreases, ADH release is inhibited, and the kidneys excrete more water, leading to increased urine output and decreased water retention.
3. Kidneys: The kidneys play a critical role in regulating water balance in the body. The kidneys filter waste products and excess water from the blood, which is then excreted as urine. The amount of water reabsorbed in the kidneys is regulated by ADH, as described above.
4. Thirst mechanism: The sensation of thirst is an important mechanism for regulating water balance. When dehydration occurs, the body senses a decrease in blood volume, which triggers the release of hormones that stimulate thirst, leading to increased water intake.
5. Electrolyte balance: Regulating water balance also involves maintaining electrolyte balance. Electrolytes, such as sodium, potassium, and chloride, are essential for proper cellular function, and their concentrations are carefully regulated by the kidneys and several hormones.
Disruptions to the regulation of water balance can lead to various disorders, such as dehydration or overhydration, which can have significant effects on electrolyte balance and cellular function.
This video introduces you to topic of ecology.It brings to you definitions of key terms used in this study.It also expounds more on Ecosystem as a key term in Ecology.
Ecology is the scientific study of how organisms interact with each other and their environment. It seeks to understand the relationships between organisms, their physical surroundings, and the natural processes that govern them. Ecology is a multidisciplinary field that incorporates knowledge and techniques from biology, geology, climatology, chemistry, physics, and mathematics to better understand complex environmental systems and their dynamics. Ecologists study the distribution and abundance of organisms, their interactions with one another, and how they are influenced by environmental factors such as temperature, rainfall, and nutrient availability. The ultimate goal of ecology is to understand and manage the natural world in a sustainable manner, ensuring that future generations can thrive in a world that is as rich and diverse as the one we inhabit today.
1. Ecosystem: A community of living organisms and their physical and chemical environment, all interacting as a system.
2. Habitat: The specific environment or locality where an organism or species naturally occurs and is adapted to live.
3. Biodiversity: The variety and abundance of living organisms in a particular ecosystem or on Earth as a whole.
4. Trophic level: The position of an organism in a food chain or web, indicative of its feeding relationships and the flow of energy through an ecosystem.
5. Keystone species: An organism that has a critical and disproportionate effect on the ecology of a community or ecosystem, often through their interactions with other species.
6. Population: A group of individuals of the same species living in a particular area at a given time.
7. Carrying capacity: The maximum number of individuals of a given species that can be supported by a particular habitat over a sustained period of time.
8. Succession: The process of gradual change in the structure and composition of an ecosystem over time, typically following a disturbance or perturbation.
9. Biogeochemical cycle: A process in which elements and compounds essential to life, such as carbon, nitrogen, and water, are transferred between living and nonliving components of an ecosystem.
10. Conservation biology: The scientific study of biodiversity and the methods used to protect and manage living organisms and ecosystems.

What is an Atom?
An atom is the basic unit of matter, and it is the smallest unit of an element that retains the chemical properties of that element. Atoms are the building blocks of all matter in the universe. They are composed of three main subatomic particles:
1. Protons: Positively charged particles found in the nucleus of the atom.
2. Neutrons: Neutrally charged particles also located in the nucleus.
3. Electrons: Negatively charged particles that orbit the nucleus in electron shells or energy levels.
The protons and neutrons are tightly packed in the central nucleus of the atom, while the electrons move in various energy levels or orbitals around the nucleus. The number of protons in an atom's nucleus defines its atomic number, which, in turn, determines the element to which the atom belongs. The number of electrons typically matches the number of protons, creating a neutral atom.
Atoms can combine to form molecules through chemical bonding, and they can participate in chemical reactions by gaining, losing, or sharing electrons. The study of atoms and their interactions is a fundamental concept in chemistry and physics and has led to a deeper understanding of the properties and behavior of matter.

This video introduces one to Organic Chemistry from the basics while also highlighting some of the basic terminologies in Organic Chemistry.
Organic chemistry is a branch of chemistry that focuses on the study of carbon compounds. Carbon atoms can form stable covalent bonds with other atoms, allowing for the formation of a wide range of complex molecules, including those found in living organisms.
Here are some basic terminologies commonly used in organic chemistry:
1. Carbon (C): Carbon is an element that forms the backbone of organic molecules. It has four valence electrons, allowing it to form four covalent bonds with other atoms.
2. Hydrocarbon: A hydrocarbon is a molecule consisting entirely of carbon and hydrogen atoms. It is the simplest type of organic compound. There are two main types of hydrocarbons: alkanes (saturated hydrocarbons) and alkenes (unsaturated hydrocarbons with a double bond).
3. Functional group: A functional group is a specific arrangement of atoms that gives a compound its characteristic chemical properties and reactivity. Examples of functional groups include alcohols, aldehydes, ketones, carboxylic acids, and amines.
4. Isomers: Isomers are compounds that have the same molecular formula but different structural arrangements or spatial orientations. There are different types of isomers, such as structural isomers (different connectivity), geometric isomers (cis-trans isomerism), and enantiomers (mirror-image isomers).
5. Alcohols: Alcohols are organic compounds that contain a hydroxyl (-OH) functional group attached to a carbon atom. They are characterized by the "-ol" suffix in their names. For example, ethanol is a common alcohol.
6. Aldehydes and Ketones: Aldehydes and ketones are organic compounds that contain a carbonyl group (C=O). Aldehydes have the carbonyl group at the end of a carbon chain, whereas ketones have it within the carbon chain.
7. Carboxylic acids: Carboxylic acids are organic compounds that contain a carboxyl group (-COOH). They are characterized by the "-oic acid" suffix in their names. Examples include acetic acid and formic acid.
8. Amines: Amines are organic compounds that contain a nitrogen atom attached to carbon atoms or hydrogen atoms. They can be classified as primary, secondary, or tertiary amines based on the number of carbon groups attached to the nitrogen atom.
These are just a few basic terminologies in organic chemistry. The subject encompasses many more concepts and reactions, including polymerization, aromatic compounds, stereochemistry, and reactions like substitution, elimination, and addition reactions.
Let's use number lines to think about Arithmetic progressions. Bonus: We wouldn't need the nth term formula after this!

![Functional Programming [Dev Concepts #4]](https://i.ytimg.com/vi/2f6oSU4Gsy4/maxresdefault.jpg)
Functional programming is a programming paradigm where programs are constructed by applying and composing functions. It is declarative rather than imperative, and the application state flows through pure functions. Functional code tends to be more predictable and easier to test than imperative or object-oriented code — but if you’re unfamiliar with it and the common patterns associated with it, functional code can also seem a lot denser.
Learn which of the programming languages are functional.

Title Bar: It displays the name of the current workbook. You can also use it to minimize, maximize, or close the Excel window.
Ribbon: Located below the title bar, the ribbon contains tabs, each with groups of related commands. You'll find tabs like Home, Insert, Page Layout, Formulas, Data, Review, and View.
Quick Access Toolbar: This customizable toolbar, located above the ribbon or below the title bar (depending on your settings), provides easy access to frequently used commands.
Worksheet Tabs: These tabs, located at the bottom of the Excel window, allow you to navigate between different worksheets within the same workbook.
Formula Bar: It's located above the worksheet grid and displays the contents of the active cell, allowing you to view and edit cell contents.
Worksheet Area: This is where you input and manipulate data. It consists of a grid of cells organized in rows and columns.
Column Headers: Letters (A, B, C, etc.) at the top of each column represent column headers. They're used to identify each column in the worksheet.
Row Headers: Numbers (1, 2, 3, etc.) on the left side of each row represent row headers. They're used to identify each row in the worksheet.
Scroll Bars: You'll find vertical and horizontal scroll bars on the right and bottom sides of the worksheet area, respectively. They allow you to navigate through large datasets.
Status Bar: Located at the bottom of the Excel window, the status bar displays information about the current status of the workbook, such as the average, count, and sum of selected cells, as well as various modes like Ready, Edit, and more.
View Buttons: These buttons, located in the bottom-right corner of the Excel window, allow you to switch between different views, such as Normal, Page Layout, and Page Break Preview.

A database is a collection of data that can be easily accessed, managed, and updated. Databases implement the CRUD operations (C - Create, R - Read, U - Update, D - Delete data) and are an important component of most modern software systems. That' is why software developers should have at least basic database skills.
In two live demos, you will learn how to create a database and a collection of documents, insert a document, and edit, delete, and query documents with MySQL and HeidiSQL, and MongoDB and Robo 3T.

This course teaches skills, not just theory. Each course video comes with carefully prepared hands-on practical exercises, where you write code to solve practical problems, run and test your solutions, maybe make mistakes, fix them, and test your code over and over until it finally works properly. The entire course provides more than 70 exercises, with automated grading in the SoftUni judge system.
Remember that coding is a skill, and it should be practiced, just like any other skill. Write code to learn the skill of coding.
To check your solutions to the practical hands-on exercises from this course, I give you free access to SoftUni's automated judge system, where you send your code, and you get automated grading: the judge tells you whether your solution is correct or wrong. This is quite useful. Try it and you will love it!

The associative property tells us that is doesn't matter how we group addition or multiplication. The property can be written like this:
a + (b + c) = (a + b) + c
a(bc) = (ab)c
http://www.rootmath.org | Algebra
Subtraction is a very poorly behaved operation. It isn't commutative and it isn't associative. But we can force it to be have by turning subtraction into addition!
a - b = a + (-b)

This lesson introduces the basics of population geography including population demography and population pyramids. Push and Pull factors of migration are also examined.
Specifically, birth rate, fertility rate, mortality rate, and infant mortality rates are defined and different types of population pyramids are examined with how they can help show the developmental status of different countries.
This lesson is provided to satisfy selected standards in the Texas Education Knowledge Standards for the World Geography studies course.
This video lesson builds on the discussion about developing and developed countries in the Population Geography lesson. In this lesson, Mr. Rueschhoff describes the United Nation's Human Development Index, how it is determined, and how it can be used to describe countries of the world.
Each of the HDI's dimensions is discussed: Long, Healthy Living, Knowledge, and Standard of Living. This includes explaining the difference between Gross National Income, Gross National Product, and Gross Domestic Product.
Mean and Expected Schooling is discussed as are literacy rates when discussing the knowledge dimension of the UN's HDI.
The lesson concludes with Mr. Rueschhoff showing the population pyramids of a developed country, developing country, and a newly industrialized country and how these relate to the UN's HDI categories.

This is part one of a two-part lesson that outlines how the agricultural and industrial revolution have shaped our world and our economic systems.
This lesson focuses on the Neolithic Revolution when mankind first discovered agriculture, the Enclosure Movement that spurred the 2nd Agricultural Revolution and the Industrial Revolution, and the Green Revolution.
Useful for all audiences, this lesson was specially designed to be used in Texas classrooms and addresses standards found in the World Geography studies and World History TEKS when it discusses the differences between Subsistence and Commercial Agriculture and the effects of the Industrial Revolution.
CORRECTION: AT 8:58, I stated that if there is just one Continental Plate you would have Convergent Subduction. I meant to say OCEANIC Plate. Sorry.
Ever heard someone say you're "making a mountain out of a molehill?" Well, I don't actually know what a molehill is (actually, I think I do), but in this lesson, we will examine the Earth's forces that creates its mountains--namely Continental Drift and Plate Tectonics.
This lesson begins by looking at the composition of the Earth and discover that its core, mantle, and crust make it much more like a baseball, than a blue marble that some have called it.
We then look at the outside of the Earth and find that it also has stitches, just like a baseball. Here we learn of Alfred Wegner's examination of the Earth which used records of fossils and rock formations to assert that the continents move--giving rise to the theory of Continental Drift.
While the geology community thought that Wegner was crazy, Harry Hess joined the Navy and through the use of sonar mapped the ocean floor and with carbon dating of the ocean crust, discovered Wegner was right and explained how the continents move through a process not unlike a lava lamp (interested, gotta watch the video--hint, it's through convection of the magma in the asthenosphere).
The lesson then looks at the three major ways that tectonic plates will move in relation to each other: divergence, convergence, and transform boundaries and discover that these moving plates create landforms such as mountains and volcanoes--and even rift valleys.
Because of the different densities, the lesson points out that if there is an oceanic crust involved in a collision of tectonic plates, it will cause something called Convergent Subduction which creates the subduction zone of the Ring of Fire. And if there are two continental plates, it creates Convergent Folding which is the process that continues to create the Himalaya Mountains and Mt. Everest.
All of the movement of these plates, creates a great deal of stress on the crust creates cracks, called faults which is where Earthquakes occur. And the lesson examines how tsunamis are created through underwater earthquakes.
Last, the lesson concludes discussing the Hot Spots that have created the Hawaii Islands as well has turned Yellowstone into a Supervolcano.
This lesson is designed for anyone, but is focused on meeting the Texas Education Knowledge Standards for the World Geography studies course in the State of Texas.

http://www.rootmath.org/calculus/estimating-limits-numerically
Introduction to the limit of a function. We cover how to find a limit by estimating it numerically and we explain why limits are useful. This technique will be made more precise in later videos where we find that our estimate and the exact value are the same.

Our third example of a limit that does not exist. This limit does not exist because the function oscillates as x approaches 0 and so the limit does not exist.

Let's explore how the graph of stopping potential vs frequency can be used to calculate the Planck's constant experimentally!
From Einstein's photoelectric equation, this graph is a straight line with the slope being a universal constant. This slope has the value of h/e. In an effort to disprove Einstein, Robert Millikan conducted experiments with various metals only to conclusively prove him right. Millikan, Einstein, and Max Planck, all won a Nobel prize for their contribution to photoelectric effect and giving birth to the quantum nature of light!

Mazar-i-Sharīf , also known as Mazar-e Sharīf or simply Mazar, is the fourth-largest city in Afghanistan by population, with an estimated 500,207 residents in 2021.[1] It is the capital of Balkh province and is linked by highways with Kunduz in the east, Kabul in the southeast, Herat in the southwest and Termez, Uzbekistan in the north. It is about 55 km (34 mi) from the Uzbek border. The city is also a tourist attraction because of its famous shrines as well as the Islamic and Hellenistic archeological sites. The ancient city of Balkh is also nearby.
The region around Mazar-i-Sharif has been historically part of Greater Khorasan and was controlled by the Tahirids followed by the Saffarids, Samanids, Ghaznavids, Ghurids, Ilkhanates, Timurids, and Khanate of Bukhara until 1751 when it became part of the Durrani Empire (although under autonomous emirs). Eventually the city passed to a few local rulers before becoming part of Afghanistan in 1849.

The United States of America was born out of the yearning of the many people who had traveled there from the old world of Europe to be free of the imperial powers that had dominated them for centuries. To have democracy, liberty, justice for all and to take command of their own destiny.
The birth of the American nation was a painful one, first by having to fight against the forces of the British and then against the indigenous people of North America, within and from outside of the new borders they had declared. In between the many conflicts, the new nation had to establish its own laws, political system and even its own culture none of which developed overnight.
Obviously, there would not always be a consensus. Over the century after 1776 when the United States of America was born, while growing under a political union of the states that it was composed of, it also saw the widening of a cultural divide between the industrious northern states and the agricultural southern states. Perhaps more than anything else, the two sides of this divide found themselves at odds over the question of slavery.
The ethics of owning a person as property became a legal battle between those in support of the practice and those opposed in American courts and halls of power. Eventually, the dispute of course became a real battlefield. More Americans died in the American Civil War that raged on the North American continent between 1861 and 1865 than in any other war in which Americans have fought throughout its history.
And while the battles have long ended, the ramifications of the civil war continue to be felt to this very day in America over issues such as culture and of course race. So, let us delve into the history of this dark chapter of American history.

During the Carboniferous life would recover from the mass extinction event at the end of the Devonian. Due to the warm, moist climate terrestrial plants would evolve greatly during this period, with the vascular seed plants beginning to dominate terrestrial forests, instead of their seedless predecessors. The bountiful forests would generate so much oxygen that the atmospheric oxygen concentration would reach its highest point in Earth's history. This in turn would give rise to some of the largest terrestrial arthropod species to ever exist. Terrestrial vertebrates continued to diversify giving rise to the first true amphibians and by the end of the period, the first true reptiles. In this video, That Bio Doc describes what life was like during the Carboniferous 358.9 - 298.9 million years ago.
This is the first in a series of videos where That Bio Doc takes on a tour of the evolutionary history of life on Earth. In this video, TBD talks about the Precambrian supereon, which covers the first ~4 billion years of life on the planet Earth. Watch and learn what early life on Earth looked like, how oxygen was introduced into the Earth's atmosphere, and how endosymbiosis changed life on Earth forever!
The evolution of complex traits such as certain behaviors, structures, and molecular pathways occurs through normal evolutionary pathways. However, these traits have sometimes been pointed to by opponents of evolutionary theory as being irreducibly complex, and thus, not able to have been produced through evolutionary mechanisms. In this video, That Bio Doc will talk about what the argument from irreducible complexity does really work and explain how mutations, such as gene duplications, can readily explain the evolution of these traits.
The Cell Cycle is the tightly regulated, orderly process cells go through prior to dividing. In this video, That Bio Doc discusses the cell cycle paying special attention to the cell cycle checkpoints that regulate the cycle and the regulatory proteins that control the movement of the cell through the cell cycle.
In the second of two videos on diseases of the immune system, That Bio Doc talks about hypersensitivities and autoimmune disorders. Hypersensitivities occur when the immune system overreacts or reacts inappropriately. Hypersensitivities include many common allergic reactions and anaphylaxis. Autoimmunities occur when the body mounts an immune response against itself. TBD talks about all of this and more!
***NOTE: There are a couple of visual glitches in this video. I will have to re-record this video when I have time. Because the audio track contains no glitches, I have decided to post this video despite the issues. ***
In this video That Bio Doc talks about the difference between natural and artificial immunity, the different strategies used to create vaccines, and herd immunity, with a special focus on COVID-19.

Learn how this complex dance between cells involving multiple receptors and battlefield antigen triggers an adaptive immune response and bring our immune system's most powerful weapons to bare!
In this second video in our series about the immune system, That Bio Doc discusses the cells that make up our immune system. Learn about the cells of the innate and adaptive immune systems, how phagocytes destroy invading pathogens, and how lymphocytes provide bodies with immunological specificity and memory.

Wander through Indonesia. From volcano landscape in East Java, Bali, to the most beautiful sunsets on Lombok. This is our cinematic travel video shot on mostly Sony A 7 III and DJI Mavic Pro 2. A couple of sequences with Panasonic Lumix GH5, Canon EOS 5D Mark IV.
We visited breathtaking waterfalls, amazing volcanoes and became friends with some local people in Nusa Penida. Enjoyed every sunrise and set. Had a ton of fun cruising on dirt bikes on Lombok.
Now with the quarantine and corona virus I finally managed to create a decent film out of all the footage. I had over 1000 clips and it was quite time consuming to go through them all.
So I hope I can at least inspire one of you guys out there !! Would appreciate a like if so.

Phases and factors affecting the phase of a substance, physical chemistry A-level.
Physical Equilibria, also known as physical phase equilibria, refers to the equilibrium between different physical states of matter such as solid, liquid, and gas. Here are some key points about physical equilibria:
1. Phase Transitions: Physical equilibria involve phase transitions, which are the changes of a substance from one phase to another. Common phase transitions include solidification (from liquid to solid), melting (from solid to liquid), vaporization (from liquid to gas), condensation (from gas to liquid), sublimation (from solid to gas), and deposition (from gas to solid).
2. Equilibrium Conditions: For a physical equilibrium to be established, the rates of the forward and backward phase transitions must be equal. This means that the amount and concentration of each phase remain constant over time.
3. Equilibrium Temperature: Each phase transition occurs at a specific temperature, known as the equilibrium temperature. This temperature depends on the pressure and composition of the system.
4. Phase Equilibrium Diagrams: Phase equilibrium diagrams, such as the water phase diagram or the phase diagram of a substance, provide a graphical representation of the conditions at which different phases coexist in equilibrium. These diagrams show the temperature and pressure ranges for each phase and the boundaries between them.
5. Triple Point: The triple point on a phase equilibrium diagram represents the unique set of conditions (temperature and pressure) at which all three phases (solid, liquid, and gas) of a substance can coexist in equilibrium.
6. Critical Point: The critical point is the temperature and pressure above which a substance can no longer exist as a distinct liquid phase, regardless of pressure. At the critical point, the liquid and gas phases are indistinguishable and merge into a supercritical fluid.
7. Phase Equilibrium Calculations: Thermodynamic models and equations, such as the Clapeyron equation or the Clausius-Clapeyron equation, are used to calculate and predict phase equilibrium conditions. These calculations require knowledge of properties such as enthalpy, entropy, and temperature.
8. Applications: Understanding physical equilibria is important in various fields, including material science, pharmaceuticals, petrochemicals, and atmospheric science. It helps in designing processes, predicting phase behavior, and optimizing the production and use of substances.
Physical equilibria play a crucial role in various natural and technological processes, and studying their behavior is fundamental to understanding the physical properties and transformations of matter.
An exponential equation is an equation in the form of y = ab^x, where a and b are constants and x is the variable.
The variable x is typically the exponent, and the base b is usually a constant greater than 1. The constant a is the initial value or y-intercept of the exponential function.
Exponential equations are used to model relationships where the value of y grows or decays exponentially with respect to x. They are commonly used in finance, population growth, radioactive decay, and other natural phenomena.
The general form of an exponential equation is:
y = ab^x
where:
- y is the dependent variable or output
- x is the independent variable or input
- a is the initial value or y-intercept
- b is the base or growth/decay factor
Examples of exponential equations:
1. Population Growth:
y = 1000 * 1.03^x
where the initial population is 1000 and it grows at a rate of 3% per year.
2. Radioactive Decay:
y = 500 * 0.9^x
where an initial amount of 500 radioactive particles decays at a rate of 10% per hour.
3. Compound Interest:
y = 1000 * (1 + 0.05)^x
where an initial investment of $1000 grows at an annual interest rate of 5%.

6 A-level paper 2 revision questions for photosynthesis
Photosynthesis is the process by which green plants make their own food using sunlight, carbon dioxide, and water. During photosynthesis, chlorophyll absorbs light energy and converts it into chemical energy which is stored in the form of glucose. Oxygen is also produced as a byproduct of photosynthesis. This process plays a significant role in maintaining the balance of oxygen and carbon dioxide in the atmosphere. The equation for photosynthesis is: 6CO2 + 6H2O + sunlight energy → C6H12O6 + 6O2.

Makerere University is looking to add value to the research conducted by the university students in order to make it commercially viable. According to Vice Chancellor Prof. Barnabas Nawangwe, this will be done through channeling resources to the university’s innovation pod, where researchers and innovators will converge to share knowledge and best practices. Prof Nawangwe's call came on the last day of the university’s 74th graduation ceremony where Henry Ssuubi, a student whose 4-year stay at Makerere has been tracked by NTV finally earned his degree in Mechanical Engineering.

We focus on constant velocity motion and look in detail at the methods for determining displacements and speeds from position vs. time data.
We see how to draw a velocity vs. time graph, given a position vs. time graph.
We connect the idea of instantaneous velocity with some ideas that you will encounter in your calculus courses.

IUPAC Nomenclature of Organic Compounds. Let's learn IUPAC Naming of Organic Compounds such as alkanes, alkenes, alkynes, and functional groups such as halides, alcohols, aldehydes, ketones and carboxylic acids. We discuss the IUPAC Naming rules with lots of examples!
![The Periodic Table of the Elements in Chemistry - [1-2-12]](https://i.ytimg.com/vi/CTwua04Ykso/maxresdefault.jpg)
h In this lesson, you will learn about the periodic table and how it is used in chemistry. We will focus on how the periodic table is organized by atomic number, and discuss how properties of elements are periodic in nature throughout the table due to the electrons in the outer shells of the atoms. We will also discuss atomic mass and valence electrons, including predicting when an atom will gain or lose an electron in a chemical reaction.
The periodic table is a tabular arrangement of elements based on their atomic number (number of protons in the nucleus). It organizes all the known elements in a specific order which allows for classification and understanding of their properties and relationships.
The table is composed of rows called periods and columns called groups or families. Elements in the same period share the same energy levels, while elements in the same group share similar chemical properties.
The elements on the periodic table are represented by symbols, and each element has its own unique atomic number, atomic mass, and chemical symbol. The order of elements is based on increasing atomic number, which also corresponds to the arrangement of electrons in an atom.
The periodic table is an essential tool for scientists, students, and researchers as it provides valuable information about elements, such as their atomic masses, electron configurations, and various trends in their chemical behavior.

Colligative properties are properties of a solution that depend solely on the concentration of solute particles in the solvent and not on the nature of the solute. One of the colligative properties is the elevation of boiling point.
The elevation of boiling point is the phenomenon where the boiling point of a solvent is raised when a non-volatile solute is dissolved in it. This occurs because the presence of solute particles in the solvent disrupts the intermolecular forces between solvent molecules, making it more difficult for the solvent to vaporize and reach its boiling point.
Some key points about the elevation of boiling point are:
1. Explanation: Dissolving a non-volatile solute in a solvent increases the number of solute particles in the solution. These solute particles create additional obstacles for solvent molecules to overcome in order to escape into the vapor phase during boiling. As a result, more energy is required to reach the boiling point, causing an elevation in the boiling point of the solution compared to the pure solvent.
2. Relationship with Concentration: The extent of the elevation of boiling point is directly proportional to the concentration of the solute particles in the solution. This relationship is described by the equation:
ΔTb = Kb * m
Where ΔTb is the elevation in boiling point, Kb is the molal boiling point elevation constant specific to the solvent, and m is the molality of the solute particles in the solution.
3. Colligative Property: The elevation of boiling point is a colligative property because it depends only on the number of solute particles and not on their size or chemical nature. This means that any solute that does not vaporize at the boiling point of the solvent will affect the boiling point similarly, regardless of its identity.
4. Applications: The elevation of boiling point has practical applications. For example, it is utilized in antifreeze solutions, where the addition of solutes (such as ethylene glycol) raises the boiling point of water in vehicle cooling systems. It also plays a role in adjusting cooking times and temperatures at higher altitudes, where the lower atmospheric pressure results in a lower boiling point of water.
It is important to note that the elevation of boiling point is just one of the colligative properties exhibited by solutions, along with other properties like vapor pressure lowering, depression of freezing point, and osmotic pressure. These properties are especially important in fields such as chemistry, biology, and pharmaceuticals and contribute to various applications and processes.

Structure Of The Leaf | Plant | Biology | The FuseSchool
Plants make food through photosynthesis. Using their leaves, plants combine sunlight, carbon dioxide and water to make glucose and oxygen. A leaf is like a plant's food factory, collecting all of the components into one place so that photosynthesis can happen.
Let's start with sunlight. The top of a leaf is exposed to the most sunlight, and so the cells specialised for trapping light are on top of the leaf. These specialised cells are called palisade mesophyll cells. They are packed full of chlorophyll - the green chemical that plants used to absorb light. Most leaves have a large surface area so that they can trap as much sunlight as possible.
Moving onto carbon dioxide. This is where the bottom of the leaf comes in. There are little pores on the bottom of the leaf called stomata. The stomata open up so that carbon dioxide can diffuse into the leaf. The stomata are controlled by 'sausage shaped' guard cells, which open up to let carbon dioxide in. The guard cells can also close the stomata, to stop other things inside the leaf, like water, from escaping.
The carbon dioxide comes in from the stomata, and then makes its way up through the leaf, through the gaps in the spongy mesophyll layer in the bottom part of the leaf and heads up to the palisade cells where photosynthesis occurs. Leaves are thin so that the carbon dioxide doesn't have too far to travel.
The final reactant needed for photosynthesis is water. Water comes into the plant through the roots, moves up the stem and enters the leaf through the vascular bundle. The vascular bundle contains a hollow tube specifically for water movement called the xylem. The veins on a leaf are actually the vascular bundle, allowing water to be spread out through the leaf.
The leaves palisade cells now have sunlight, carbon dioxide and water. They are ready to photosynthesis to make glucose and oxygen.
How do leaves manage to let in the wanted things (like water and carbon dioxide) but prevent unwanted things like bacteria getting in and also prevent the reactants from escaping before being used? At the top and bottom of the leaf are epidermis cells. These produce a protective waxy cuticle layer. The waxy cuticle seals up the leaf so that the only way in and out are through the stomata, which are regulated by the guard cells.
So from top to bottom, a leaf's structure:
- Waxy cuticle and epidermis cells
- Palisade cells (where photosynthesis occurs)
- Spongy mesophyll (with vascular bundle running through for water transport)
- Epidermis and cuticle, with stomata and guard cells spread throughout (allowing carbon dioxide in).
