2. There is a widely used herbicide (weed killer) called Roundup. Roundup kills any plant that it touches.
Scientists have genetically altered soybeans and other crop plants to create "Roundup Ready" strains that
are not killed by Roundup. By planting Roundup Ready seeds, a farmer can control weeds by spraying
Roundup right over the crop. The crop completely ignores the herbicide, but the weeds are eliminated.
This technique is known as

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
