Conditions under which natural selection occurs in a population of iguanas are described in the table below: Natural Selection Description Condition Description A Iguanas that were good swimmers and divers had the advantage of finding food in the water over other iguanas B The larger hatchlings produced by larger female iguanas had a higher chance of survival Which factor contributes to natural selection for each condition? Condition A represents competition, and Condition B represents differential reproductive success. Condition A represents differential reproductive success, and Condition B represents competition. Condition A represents inherited variation, and Condition B represents competition. Condition A represents competition, and Condition B represents inherited variation. Please help!

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
