G Anaerobic glycolysis of glucose produces a smaller number of ATPs per glucose molecule in red blood cells than in muscle cells, because: a. Red blood cells lack phosphoglycerate kinase b. Red blood cells contain an enzyme that is capable of converting 1,3-bisphosphoglycerate to 2,3-bisphosphoglycerate c. Red blood cells do not have mitochondria d. Red blood cells do not have a nucleus e. All of the above

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
