Answer:

<em>Microevolution</em>

Explanation:

In ecological studies, microevolution can be described as the changes which arise in the allele frequencies of a population over a short period of time. These changes arise due to conditions such as a mutation which might be beneficial, genetic drift, genetic flow etc. Microevolution is caused when allele for certain traits are more favoured by the changing environment.

For example, the allele frequencies of a population might change after they become pest resistant.

Answer:

D

Explanation:

Key points:

- Cells have a variety of mechanisms to prevent mutations, or permanent changes in DNA sequence.

- During DNA synthesis, most DNA polymerases "check their work," fixing the majority of mispaired bases in a process called proofreading.

- Immediately after DNA synthesis, any remaining mispaired bases can be detected and replaced in a process called mismatch repair.

- If DNA gets damaged, it can be repaired by various mechanisms, including chemical reversal, excision repair, and double-stranded break repair.
