D. Populations evolve as natural selection results in a change in the frequency of alleles within the population over time.
Our current understanding about how species evolve is natural selection produces adaptations vital to the survival of organisms.
7)
B. The relative frequency of the mutation will increase as time passes.
The information provided makes it clear that the mutation is an advantageous mutation; according to the theory of natural selection, since the mutation is beneficial to the bacteria, those with the mutation will survive and reproduce more, passing on the mutation. This way, the frequency of the mutation will increase.
Answer:

Instead, they are likely to have causes such as lifestyle factors, environmental toxins, or gene mutations. Common types of noninfectious diseases include cancer, diabetes, and immune system diseases.
