Answer:

1) Amino acids

2) option C is false

3) evolution

Explanation:

Remarkably, all of the different proteins in a cell are made from the same 20 amino acids

⇒ proteins are made of a combination of amino acids. The amino acids get conected by petide bonds.

A) A mutation is a change in the DNA that can generate offspring less fit for survival than their parents. This is true, changes in DNA of the parents can cause the deviations/ defects for the next generation i.e. daltonism where the mother is a carrier but hasn't a disadvantage, and the son is also a carrier but he does have disadvantages.

B) A mutation can be a result of imperfect DNA duplication.This is true, i.e hereditary cancer.

C) A mutation is a result of sexual reproduction. This is FALSE. A mutation is the result of a defect in the reproduction. It's an abnormal situation.

D) A mutation is a change in the DNA that can generate offspring that are as fit for survival as their parents are. This is true. Not all mutations give defects, but can also create advantages !

Option C "A mutation is a result of sexual reproduction" is false.

The process of change and selection over the course of many generations is the basis of evolution.

⇒Evolution exists because of the changes that happen in the body and generations.
