Detailed explanation-1: -Finch populations with a certain beak shape thrived, while those not having that beak shape decreased. Which of the following describes a necessary condition for these changes in the finch populations to occur? Limited resources are a major driving factor for natural selection.

Detailed explanation-2: -There was an increase in the amount of large beaked finches because the finches with smaller beaks died off. The reason for that is that the small soft seeds became hard to find, so the birds well adapted to them struggled to eat.

Detailed explanation-3: -Microevolution is visible when the bigger beaks of finches are expressed more over time because it can help their species survive better. 2. It is common for populations to satisfy the Hardy-Weinberg Equilibrium.

Detailed explanation-4: -All the finches on the island have very small beaks. How might this environmental change impact the survival of this finch population? Only those finches that can find another food source or those with beaks large enough to crack the seeds will survive.

Detailed explanation-5: -A small population of chimpanzees lives in a habitat that undergoes no changes for a long period. How will genetic drift probably affect this population? It will reduce genetic diversity. A small portion of the population that is geographically isolated from the rest of the population runs the risk of decreased.
