Although there is no diagrammatic representation of the food web but the question can be answered based on the provided information. The answer is:

Sawgrass → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level.

Explanation:

Food web is an interconnected food chain i.e. a series of food chains clustered together. A food web represents the various ways one organism can feed on another in a cycle. Since a food web consists of many food chains, energy is transferred when one organism feeds on another (flow of energy).

Just like a food chain, a food web begins with a PRODUCER, which is an organism capable of producing its own food via photosynthesis. This is the case of mangrove and sawgrass in this depicted food web as they are both producers and hence, must start the food web i.e. be at the bottom of the food web. Organisms called CONSUMERS feed on producers and one another to obtain energy. Consumers can be primary, secondary or tertiary depending on the organism they feed on. Primary consumers feed directly on producers, secondary consumer on primary and tertiary consumers on secondary, in that order.

This accounts for why the American Alligator is at the top of the food web because it is a tertiary consumer.

However, as organisms feed on one another, only about 10% of the available energy is transferred because most of the energy (about 90%) has been used for metabolic processes and hence, lost as heat.

Therefore, the best description for the flow of energy in the Everglades food web is:

Sawgrass → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level.

Sawgrass is the producer and must begin the energy flow, followed by a primary consumer (insect). Feeding continues in that order until the tertiary consumer (American alligator) is reached.

Answer:

b) Mangrove → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level.

Metamorphic rock, well for your answer just metamorphic.

Explanation:

Because, they are formed from any rocks by heat and/or pressure to create a new rock.

Rocks created from intense heat or pressure deep inside the earth are called metamorphic. Thus, the correct option for this question is D.

Metamorphic rocks are formed when specific rocks are subjected to intense heat, high pressure, hot mineral-rich fluids, or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.

When rock changes its properties or attributes over a period of time due to physical changes like pressure, heat, and different chemical activity.

When sedimentary rocks or igneous rocks undergo this alteration through the physical process such as pressure exposure, heat changes, and tectonic plate movement at the plate edges, metamorphic rocks are formed.

Therefore, rocks created from intense heat or pressure deep inside the earth are called metamorphic. Thus, the correct option for this question is D.

Explanation:

The domestication of animals and the development of agriculture are likely causes for the rise in population growth that occurred 8,000 years ago. Prior to the domestication of animals and the development of agriculture, human populations relied primarily on hunting and gathering for their food. These methods of food acquisition were often unreliable and limited the growth of human populations.

With the domestication of animals, humans were able to produce a steady source of food and protein through the raising of livestock. This allowed for the growth of larger, more settled human populations. Additionally, the development of agriculture made it possible for humans to grow their own food, which greatly increased the amount of food available to them. This allowed for population growth as people no longer had to rely solely on hunting and gathering for food.

The combination of these two advancements in food production allowed for a significant increase in population growth, as people were able to produce more food and feed more people. This led to the rise of settled agricultural societies and the development of civilizations.

The statement not supported by Kettlewell's data is "Light moths had a survival disadvantage in industrial Dorset," while the other statements are supported by the experiment's results.

The statement that Kettlewell's statistics does not support is: "Light moths had a survival disadvantage in industrial Dorset."Kettlewell's data showed that dark moths had a survival advantage in forested Birmingham, where the tree trunks were darkened by pollution, making the dark moths harder to spot by predators. In contrast, light moths had a survival advantage in forested Birmingham before industrialization when tree trunks were lighter in color.

In industrial Dorset, where pollution had darkened the tree trunks, Kettlewell found that dark moths had a survival advantage, as they were better camouflaged against the darker tree trunks. Light moths, on the other hand, had a survival disadvantage in industrial Dorset, as they were more visible to predators against the darkened tree trunks.

Comparisons of amino acid sequences can shed light on the evolutionary divergence of related species. If you were comparing two living species, would you expect all proteins to show the same degree of divergence? Select the two correct statements.

Answer:

3) All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure.

4) All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways.

Explanation:

In this example, we are comparing different species, although we do not know how different they are. Changes in the proteins reflect the divergence between groups during evolution. Among different animals and plants, changes in proteins and their following maintenance can be associated with a group divergence and evolution.

The same proteins amino acid sequences in different species provide information about the divergence point between both species. Probably, the origin of genes and protein changes and the subsequent fixation of those changes by natural selection is the cause of most of the phenotypic variation observed between species. So, genes and proteins are subdued to selective pressures that vary according to the environment and the species.

In populations of the same species inhabiting different places with different environmental characteristics suffer changes that respond to their life habits. Proteins evolve in different degrees and take different routes, influenced by the selective pressures of the environment surrounding them. Ecological, behavioral, reproductive pressures, among others, vary between populations according to their own needs and produce changes that "model" the organisms when fixating. These changes are inherited generation after generation, leading to a divergence in the species.

ATP and NADPH serve as key molecules that connect the light-dependent and light-independent reactions in photosynthesis. They play crucial roles in transferring energy and reducing power between the two processes, ensuring the overall efficiency of photosynthesis.

1. Light-Dependent Reactions: These reactions occur in the thylakoid membranes of the chloroplasts and convert light energy into chemical energy. During this process, light energy is absorbed by chlorophyll and other pigments, leading to the generation of ATP and NADPH.

2. ATP Generation: The absorbed light energy is used to power the electron transport chain, which pumps protons across the thylakoid membrane, creating a proton gradient. The flow of protons back across the membrane through ATP synthase generates ATP from ADP and inorganic phosphate.

3. NADPH Generation: Simultaneously, the energized electrons from the electron transport chain are transferred to NADP+, reducing it to NADPH. This process requires the input of high-energy electrons and protons.

4. Light-Independent Reactions (Calvin Cycle): ATP and NADPH generated during the light-dependent reactions are utilized in the stroma of the chloroplasts to fuel the Calvin cycle. Here, carbon dioxide is fixed and converted into glucose through a series of enzymatic reactions.

5. ATP Utilization: ATP provides the necessary energy to power the various enzyme-catalyzed reactions in the Calvin cycle. It is used to drive the carboxylation of ribulose bisphosphate (RuBP), the regeneration of RuBP, and other key steps in the cycle.

6. NADPH Utilization: NADPH functions as a reducing agent in the Calvin cycle, providing the necessary high-energy electrons to convert carbon dioxide into glucose. It acts as a source of electrons in the reduction of 3-phosphoglycerate to glyceraldehyde 3-phosphate (G3P).

7. Recycling of ADP, NADP+, and Pi: As ATP is hydrolyzed to ADP and inorganic phosphate (Pi) during the Calvin cycle, ADP and Pi are regenerated in the light-dependent reactions. Similarly, NADP+ is regenerated from NADPH.

8. Continuous Cycle: The production of ATP and NADPH in the light-dependent reactions and their utilization in the light-independent reactions create a continuous cycle, ensuring the flow of energy and reducing power required for photosynthesis.

In summary, ATP and NADPH act as energy and reducing power carriers, respectively, connecting the light-dependent reactions that capture light energy with the light-independent reactions that utilize this energy to produce glucose. Their continuous generation and utilization ensure the efficiency and functionality of photosynthesis.

Answer: A decreased ability of the enzyme to bind substrates.

Explanation: Hope this helps!

The disruption of the active site of an enzyme would most likely result in the enzyme's decreased ability to bind to the substrate. Hence, the third statement is correct.

Enzyme is a biocatalyst that reduces a substrate's activation energy and converts it to the product. The enzyme has an active site at which the substrate binds. After binding to the active site of an enzyme, the substrate is converted into products by making or breaking a few bonds. If active site doesn't function then substrate can't bind.

Apart from the active site, the enzyme has other sites, such as the allosteric site. At this site, allosteric regulators bind. These allosteric molecules may be activators or repressors. Activator allosteric regulators increase the enzyme function, while repressor allosteric regulators repress the enzyme function by reducing the catalysis. Activators increase the catalysis rate.

The Process of Cellular Respiration

Cellular respiration is the process of extracting energy in the form of ATP from the glucose in the food you eat. How does cellular respiration happen inside of the cell? Cellular respiration is a three step process. Briefly:

In stage one, glucose is broken down in the cytoplasm of the cell in a process called glycolysis.

In stage two, the pyruvate molecules are transported into the mitochondria. The mitochondria are the organelles known as the energy "powerhouses" of the cells (Figure below). In the mitochondria, the pyruvate, which have been converted into a 2-carbon molecule, enter the Krebs cycle. Notice that mitochondria have an inner membrane with many folds, called cristae. These cristae greatly increase the membrane surface area where many of the cellular respiration reactions take place.

In stage three, the energy in the energy carriers enters an electron transport chain. During this step, this energy is used to produce ATP.

Oxygen is needed to help the process of turning glucose into ATP. The initial step releases just two molecules of ATP for each glucose. The later steps release much more ATP.

The process is of cellular respiration. Cellular respiration is the process through which the glucose in the food you eat is converted into ATP, which is then converted into energy.

What is cellular respiration?

In the first stage, a procedure known as glycolysis breaks down glucose in the cell's cytoplasm.

The pyruvate molecules are delivered to the mitochondria in stage two. The organelles known as the cellular "powerhouses" of energy are called mitochondria
