Flamingos get their color by eating certain types of crustaceans.  Some flamingos aren’t very good at finding food and are white, and some have adaptations that make finding food easy and they are red.  Pink males find an intermediate amount of food and have lots of time to court females, so they are deemed most attractive by females.  This scenario describes what selection type?  

Read the following scenario to answer the following question(s).Over the past 60 years, many amphibian species have experienced significant population declines and some species have become extinct. Scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. However, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. These global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. In Switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction.When most populations of a wide-ranging amphibian species are lost and the few remaining populations are widely separated, we expect to see that ______.

The use of the Indian mongoose to control rat populations

Bears eat berries, humans, and large fish; large fish eat smaller fish and insects; humans eat bears, large fish, and berries; Venus flytraps eat insects. The scenario described here is an example of ______.

Refer to the following figure. If there were an additional trophic level that consisted of organisms that prey on snakes, about how much energy would be available to organisms at that trophic level?

The superficial femoral vein is a _______ vein.

The first branch of the internal carotid artery with clinical significance is the

In Switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction.Some biologists urge the collection of the few remaining individuals of some of the most threatened amphibian species, to preserve them if they become extinct in the wild. If such captive breeding programs could produce thousands of individuals from just a few of the remaining survivors, the species will still be threatened because of ______.

Which type of plaque is visualized sonographically as echogenic with posterior acoustic shadowing?

The 2 vertebral arteries unite to form the
