Answer: option B) A gene can take different forms called alleles.
Explanation:
An allele is one of the two or more different forms of the same gene.
For example, a trait such as seed shape is represented expressed a gene, but with allele of "RR" (round seeds) and "rr"(wrinkled seeds) observed physically by the farmers.
Thus, the correct answer is that a gene can take different forms called alleles.

Given what we know, we can confirm that the area of biology that states that living things undergo gradual, structural, and functional changes over long periods of time is referred to as evolution.
<h3>What we know about evolution. </h3>
- This is a theory that was put forward by Charles Darwin.
- Evolution accounts for the structural and functional changes that are passed down from one generation to the next.
- The changes produced by evolution are very slow in that they may take many generations to complete a noticeably change.
- These changes are hereditary.
Therefore, we can confirm that the theory of evolution put forward by Charles Darwin states that living things undergo gradual, structural, and functional changes over long periods of time.

The reason for the change in the hands of the chimpanzee include:
- Crossbreeding between gorillas and chimpanzees( Represents a reason for the change)
- Mutations in chimpanzee DNA ( Represents a reason for the change)
- Differences in the ways chimpanzees use their hands ( Doesn't represents a reason for the change)
- Sexual reproduction ( Doesn't represents a reason for the change)
- Differences in enhancer sequences( Represents a reason for the change).
<h3>What is mutation?</h3>
Mutation is defined as the alteration in the genetic makeup of a living organism which may occur due to the following:
- When there is spontaneous break down of deoxyribonucleic acid (DNA).
- Change in a single nucleotide of the DNA.
- when there is additions or deletions of nucleotide in a DNA strand.
A change can be noticed in an animal such as Chimpanzee when the following occurs:
Mutations in chimpanzee DNA: This can alter both that anatomy and the physiological features of the organism involved.
Crossbreeding between gorillas and chimpanzees: When there is cross breeding between a chimpanzee and a gorilla, it will lead to a genetic diversity which can be observed as a change in the hands of the chimpanzee.
