Answer:
A mutation is the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Mutations in sex cells are more serious because they are heritable and affect the next generation.

Answer:
a vestigial structure
Explanation:
Vestigial structures are a rudimentary (or even functionless) version of a body part, but they have important functions in a closely correlated or evolutionarily close species, an example of which is the presence of eyes in fish of the genus Astyanax. The existence of these vestigial structures is strong evidence that evolution occurs in organisms, since this structure, today without much apparent function, may in the past have been extremely important to the ancestors of that species.

B. Population is the answer
Given what we know about nutrition, we can confirm that the runner's meal would have to contain 30 grams of protein.
The runner in question wishes to complete a two-hour run while expending 4kcal or calories <u><em>per minute</em></u>, for a total of 480kcal. Furthermore, the runner wishes for only 25% (120kcal) of this energy to come from a source of protein.
Since <em><u>every gram of </u></em><em><u>protein </u></em><em><u>adds </u></em><em><u>4 calories </u></em><em><u>of energy to the meal</u></em>, and we have to account for 120 calories, the runner will have to consume 30 grams of protein to achieve the desired results.
