C) enhancer
D) good-enough
The answer to this question is A) defeated

Answer:
e. is under purifying selection
Explanation:
Purifying selection removes deleterious alleles that can arise through
random mutations
.
Mutations may or may not have consequences at the level of genetic expression depending on whether those mutations are synonymous or nonsynonymous. Synonymous mutations do not generate changes in the protein to be encoded while non-synonymous ones do.
Important genes for the development of the organism - such as those involved in the neural development- are very likely to be under purifying selection, eliminating individuals with deleterious alleles since those alleles (product of non-synonymous substitutions) do not allow the individuals to survive.

Doubling time is the time taken by the plants, bacteria or animals to raise or double its population. Yes, the doubling time is indeed seven days.
<h3>What is the doubling rate?</h3>
Doubling time is the rate of the time taken by the bacteria or plant to double its population from the given number. On day 1, the population of the water lilies were 2 and on day 7, it was found to be 4. This depicts that the population got doubled in seven days.
On day 10, it grew to 10 and on day 17 to 20. In the duration of seven days, the population of the water Lilly doubled. From this, it can be said that the population of the plant got doubled.
Thus, the doubling time is seven days.
