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 correct answer is:
d.
all of the above
Explanation:
In plate tectonics, a convergent boundary, also recognized as a destructive plate boundary, is a section of active deformation where two or more tectonic plates or parts of the lithosphere are near the edge of their life cycle. If two tectonic plates strike, they create a convergent plate boundary.
They need to replicate themselves to make sure they don't get smaller.
