- The presence of various alleles, or different gene versions, within a population indicates genetic variety.
- If there is genetic variation, then everybody in the population will have various genotypes depending on the alleles they carry.

Your answer for this question is paper which Is A
Answer:
<u><em>Oxygen</em></u>
Explanation:
Cellular respiration can be described as a process by which cells produce carbon dioxide and water from oxygen and glucose. Huge amounts of ATP is generated by this process. This ATP is used to carry out the normal functions of a cell.
If the oxygen supply to the frog species becomes low, then the process of cellular respiration will also slow down. Hence, by altering the amount of oxygen, the amount of ATP can be altered.
The correct answer is Antigen
