Answer 1

Based on your description of a population of beetles before and after the impact of bird predators, the type of selection represented could be **directional selection**.

In directional selection, one phenotype is favored over others, causing the allele frequency to shift in one direction. If, for example, the predators are causing a decrease in the population of beetles with certain traits (e.g., smaller size), the population may evolve toward a larger size as those individuals survive better.

If you see the phenotypes before the impact and then a clear shift towards one extreme after the impact, that suggests directional selection.

If you can provide more details or context from the diagram, I may be able to give a more precise answer.
