B, the others are not testable under lab conditions.
Answer:
The allele frequencies of both populations are likely to be similar.
Explanation:
An allele is a variant form of a given gene. Sometimes different alleles can cause variations in the observable characteristics of the species examined.
In the option given the chance that alleles are similar is very high because both populations exchange migrants very frequently and at a high rate so the genes of both populations are mixed very often.
I hope this answer helps you.
Answer:
Explanation:
A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. Glaciers slowly deform and flow under stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques, moraines, or fjords. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that forms on the surface of bodies of water.
