Which of the following is a reservoir for carbon and nitrogen, but not phosphorus?

In enzyme-controlled reactions, a substrate is the reactant or the molecule upon which the enzyme acts. They interact at the enzyme's active site and undergo dynamic changes to facilitate the chemical reaction. Each enzyme is designed to work with a specific substrate.

In an enzyme-controlled reaction, a substrate is essentially the reactant, or the molecule upon which the enzyme acts. The enzyme binds to the substrate at a specific location known as the active site. This binding is facilitated by the unique combination of amino acid side chains within the active site, perfectly suited to bind to one specific chemical substrate (or substrates). Enzymes display specificity because only a substrate with a particular shape and electrical charge can bind to the corresponding active site.

Moreover, enzymes and substrates undergo dynamic changes to induce the transition state of the substrate - a high-energy, unstable state occurring during a chemical reaction. This process known as induced fit, resembles a hand fitting into a glove, where the glove represents the enzyme and the hand represents the substrate.

Therefore, we say that each enzyme is specifically matched for each substrate and hence each chemical reaction. Some enzymes, however, can act on several different but structurally related substrates.

A substrate in an enzyme-controlled reaction is the molecule that the enzyme acts upon. It binds to the enzyme's active site, undergoes a chemical reaction, and is converted into a product. Substrates are crucial for the specificity and the catalytic process of enzymes.

In an enzyme-controlled reaction, a substrate is the molecule that binds to the enzyme's active site. The enzyme catalyzes a chemical reaction, transforming the substrate into a different molecule, known as the product. This process often involves the formation of an enzyme-substrate complex, indicated by the equation E+S
ightarrow ES
ightarrow E+P, where E represents the enzyme, S is the substrate, and P is the product.

Enzymes are highly specific to their substrates due to the unique fit between the substrate and the enzyme's active site, a concept sometimes referred to as the "lock and key" model. However, the induced fit model explains that the active site of the enzyme changes shape upon substrate binding, which facilitates the catalytic process. Substrates play a critical role in biochemical reactions and are not altered or consumed by the reaction, allowing enzymes to be reused multiple times.

Explanation:

To remedy overly acidic soil, a gardener can add lime which reacts with hydrogen ions in the soil to form water and carbonate ions. This neutralizes the acidity of the soil, making it more suitable for plant growth. Contributing to soil acidity is the phenomenon of acid rain, caused by human activities like burning of fossil fuels.

To remedy soil that is overly acidic, a gardener can add a substance, such as lime (calcium carbonate, CaCO3) to the soil. When lime is added to acidic soil, it reacts with the hydrogen ions present in the soil to form water and carbonate ions. This reaction can be represented as:

CaCO3 + 2H+ -> Ca2+ + H2O + CO2

The carbonate ions (CO2) evaporate into the atmosphere as carbon dioxide gas. This chemical reaction neutralizes the acidity of the soil (raises the pH), making it more hospitable for plant growth. In addition, certain human activities can affect the pH of soil, such as the burning of fossil fuels, which releases sulfur dioxide into the atmosphere. This can result in acid rain (rainwater combined with sulfur dioxide forms weak sulfuric acid), which can lower the pH of soil, making it overly acidic.

To remedy soil that is overly acidic, a gardener can use various methods to raise the pH level and make the soil more neutral. One common method is to add lime, such as agricultural lime or dolomitic lime, to the soil. When lime is added to acidic soil, it reacts with the H+ ions in the soil to form water, thus decreasing the acidity. The chemical reaction involved can be represented as:

CaCO3 + 2H+ → Ca2+ + H2O + CO2

Another method is to add organic matter, such as compost or manure, to the soil. The organic matter contains alkaline compounds that can help neutralize the acidity. For example, the reaction between organic matter and acid in the soil can be represented as:

Organic matter + H+ → H2O + CO2

Final answer:

Sensory receptors are specialized neurons that detect stimuli and start the process of sensory perception, involving reception, transduction, encoding, transmission, and interpretation in the brain. Each type of sensory input has a specific pathway and modality by which it is processed and perceived. This process ensures the conversion of external stimuli into a meaningful experience.

Explanation:

Sensory receptors are the raw data of experience, based on the activation of certain receptors located in the various sensory organs. When a physical or chemical stimulus is detected by a sensory receptor, sensation occurs. The process from a sensory input to a perceived experience involves several steps: reception, transduction, encoding and transmission, and finally, perception.

During the reception phase, sensory receptors are activated by stimuli such as mechanical stimuli, chemicals, or temperature. The transduction phase is where these stimuli are converted into neural signals. Then, through encoding and transmission, these neural signals are processed regarding the type of stimulus, the location, the duration, and the intensity. The sensory information is carried by action potentials along neurons, ensuring that the senses are kept separate as they are transmitted to the brain. Finally, perception occurs in the brain, where the information is interpreted and becomes part of our conscious experience, as depicted in Figure 7.2, which illustrates that sensations and information received by the brain are filtered through emotions and memories to become thoughts.

The main sensory modalities include olfaction (smell), gustation (taste), equilibrium (balance), hearing, and the general senses of somatosensation such as touch, pressure, and pain. Each modality is encoded and transduced in a specific manner unique to the type of sensory input it represents.

I believe the only reason why they could have survived successfully despite living only on the same tree and they are large in number is because:

“They feed on different parts of the same trees.”

So this means that although they are many of them feeding on the tree, there is no food deficiency occurring since they are getting their source of food from different parts of the tree anyway.

Answer:The fish shares a niche with another species (apex)

Explanation:

Answer: Option (c) is the correct answer.

Explanation:

A compound that consists of only carbon and hydrogen atoms is known as a hydrocarbon.

For example, [tex]C_{5}H_{12}[/tex] is a hydrocarbon and its name is pentane.

A hydrocarbon can have single, double or triple bonds. A hydrocarbon with double bonds is known as an alkene and a hydrocarbon with a triple bond is known as an alkyne.

A hydrocarbon does not have or contain an oxygen atom.

Hence, we can conclude that the statement no, a hydrocarbon contains only carbon and hydrogen atoms, is correct.
