The statement that is true regarding the reactions that occur in the Calvin cycle is that it consumes energy.

<h3>What is Calvin cycle?</h3>

Calvin cycle of photosynthesis is a series of biochemical reactions that take place in the stroma of chloroplasts in photosynthetic organisms.

The Calvin cycle also called light independent or dark reaction is the second stage of the photosynthetic process. It is so called because it does not require light to occur.

The Calvin cycle makes use of the products of the light stage (ATP and NADPH) to synthesize carbohydrates.

However, the series of reaction is an energy consuming one, which makes use of ATP to occur.

Therefore, the statement that is true regarding the reactions that occur in the Calvin cycle is that it consumes energy.

What is the definition of biological evolution and what does it have to do with populations?
katrin [286]

Answer:

Definition:

Biological evolution is the process through which the characteristics of organisms change over successive generations, by means of genetic variation and natural selection. It is most commonly defined as "changes in gene frequencies in populations."

A small change in genes could result in a mass epidemic. Such as the colinistists bringing yellow fever over to America.

Explanation:

Biological evolution refers to the cumulative changes that occur in a population over time. These changes are produced at the genetic level as organisms' genes mutate and/or recombine in different ways during reproduction and are passed on to future generations.
