Answer:
E. This population is in Hardy-Weinberg equilibrium.
Explanation:
A population in Hardy-Weinberg equilibrium maintains constant allele and genotype frequencies over generations. To obtain the Hardy-Weinberg equilibrium, none of the evolutionary forces (genetic drift, mutation, natural selection, etc.) should be operative on the gene pool as they deviate the population from the equilibrium.
According to the given information, the allele frequencies and hence the genotype frequencies in a population of butterflies are constant over two decades. This shows that the population is at Hardy-Weinberg equilibrium and is not evolving.
The surface of the Earth is dynamic, and landforms change throughout time as a result of weathering and other surface activities.

It tells you that a large amount of their brain processing is oriented towards visual cues/stimuli. Because they can view a much larger degree of range laterally than can humans and need to be able to.
