Aresearcher wants to know if gene flow is contributing to evolution of drought tolerance of pitcher plants in a specific bog. as a control, she should a. determine if the population is in hardy-weinberg equilibrium b. transplant pitcher plants from other populations into the bog. oc. estimate the frequency of alleles at relevant genes for drought tolerance. d. all of the above steps should be taken. e. none of these steps should be taken; gene flow does not contribute to evolution.

What part of the plant has the most chloroplsts?

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
