You are organizing a soap box derby on the slopes of Mount Rushmore. To get approval from Parks and Recreation, you are required to provide proof that the cars will not exceed a speed of 10 m/s. You establish a research team to
construct a track and race car to determine the maximum vertical height the cars can begin the race without
exceeding 10 m/s at the finish line. You will then use the data from the research to obtain permits from Parks and
Recreation to hold the event.

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. chytridiomycosis is a fungal disease first identified in 1998 as a cause of massive amphibian deaths. in some severely impacted populations, a few individuals have survived, perhaps because of some natural resistance. if these resistant individuals continue to survive and prosper, new resistant populations might emerge. this would be an example of the founder effect artificial selection genetic drift natural selection sexual selection
