Microevolution refers to changes that occur within a single species or group or organisms.  Microevolution, as opposed to macroevolution, occurs in a short period of time. In microevolution, the ancestor and the descendant obviously belong to the same type.  For example, certain pests have evolved in such a way that they become immune to pesticides; the same thing has happened to certain weeds and herbicides. Hope this helps.

6. Which of these BEST describes our current understanding about how species evolve over time?
trapecia [35]
Hello!

6)
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.
