On an adventure to a faraway place, you discover two previously unknown species of woozle. You notice that purple woozles live on the ground and orange woozles live high up in the trees. You gather up all of the purple woozles (they're easier to catch) and take them to a zoo. The next year, when you return to gather up the orange woozles, you find that they now live on the ground as well as in the trees. Based on what you know about niches and competition, which of the following is TRUE? a. Competition between purple and orange woozles might have been responsible for where you found them on the island.
b. The fundamental niches of orange woozles does not include ground habitat.
c. On the ground, purple woozles are probably poorer competitors than orange woozles.

Read the following scenario to answer the following question. 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 a. the founder effect becomes increasingly important b. microevolution no longer occurs c. gene flow between populations is reduced d. artificial selection becomes a greater factor in microevolution

Ras is a g-protein that is activated when a growth factor attaches to egfr. its activation results in the replacement of a gdp molecule with a gtp molecule, thus allowing a signal transduction pathway to be activated. considering the signal pathway illustrated on this page, what is one potential outcome of a mutation in the ras gene that leads to ras protein hyperactivity. be specific.
