The diagram shows the approximate amounts of carbon, in gigatons (Gt) per year, that move through the primary processes
of the carbon cycle. The numbers in yellow are due to natural processes, and the numbers in red are the result of human
actions. Based on this diagram, complete the statements.

Answers

Answer 1

Human activities release 9 gigatons of carbon into the atmosphere each year.

Human activities remove 5 gigatons of carbon from the atmosphere each year.

Humans’ net contribution of atmospheric carbon to the atmosphere is 4 gigatons each year.

Answer 2

9 gigatonnes of carbon are released into the atmosphere annually by human activity. Each year, 5 gigatonnes of carbon are removed from the atmosphere by human activity.

Thus, Each year, 4 gigatons of atmospheric carbon are added to the atmosphere as a result of human activity.

A fundamental mechanism that controls the movement of carbon dioxide and other carbon compounds between the atmosphere, oceans, soil, and living things on Earth is known as the carbon cycle. The concentration of carbon in various reservoirs is influenced by a variety of natural and human factors.

Plants and other photosynthetic creatures take up about 120 Gt of carbon each year from the atmosphere through the process of photosynthesis (yellow).

Thus, 9 gigatonnes of carbon are released into the atmosphere annually by human activity. Each year, 5 gigatonnes of carbon are removed from the atmosphere by human activity.

what is the function of circuit breakers and fuses?

Answers

Answer:

Fuses and Circuit Breakers both serve the same purpose – which is to protect electrical circuits by preventing overloads that can cause fires. They both interrupt the flow of electricity, but in very different ways from each other. While a fuse is made of a piece of metal that melts when overheated, circuit breakers on the other hand, have internal switch mechanisms that can be tripped by an unsafe surge of electricity.

Fuses can be quicker for interrupting the flow of power, but when they melt they must be replaced; circuit breakers on the other hand just need to be reset. When comparing the two, we’ll take a look at some of the major advantages and disadvantages between fuses and circuit breakers to distinguish between them.

when the lac repressor protein binds to lactose, why does it fall off its binding site at the operator?

Answers

Answer:

English is not my native language so sry if there's any grammaticaly mistake

Explanation:

cuz it changes its shape and forme u got that?!

Lactose falls off its binding site at the operator because the allolactose binds to the repressor causing it to fall off the operator side.

What do you mean by Lac repressor?

Lac repressor prevents the transcription of genes involved in lactose utilization in E. coli, such as lac genes.

When lactose becomes available a small amount of it is taken up by lactose permease and converted to allolactose by the enzyme beta-galactosidase.

Therefore, Lactose falls off its binding site at the operator because the allolactose binds to the repressor causing it to fall off the operator side.

In the citric acid cycle, the enzyme succinate dehydrogenase catalyzes a reversible reaction using FAD/FADH2 as an oxidizing/reducing agent. Which of the following statements best explains how the redox component of this reaction contributes to the reaction's ability to be reversible under cellular conditions?
A. FAD has no reduction potential when it is enzyme-bound.
B. FAD can be reduced by the sequential addition of one hydrogen at a time.
C. FAD/FADH2 is covalently bound to succinate dehydrogenase.
D. The change in the biochemical standard reduction potential is small.

Answers

The statement which best explains how the redox component of this reaction contributes to the reaction's ability to be reversible under cellular conditions is; Choice D: The change in the biochemical standard reduction potential is small.

Discussion:

A reversible process is one in which the system and environment can be restored to exactly the same initial states that they were in prior to when the process occurred, if we go backward along the path of the process.

However, the necessary condition for a reversible process is therefore the quasi-static requirement.

The quasi-static requirement in this case is that the change in the biochemical standard reduction potential is small.
