The author claims that physically active people do not burn more calories than their less active counterparts. This suggests that at the cellular level, some changes have to occur in order to allow these 2 individuals to burn similar amounts of energy. Based on the glycolysis and cellular respiration concepts that you covered in BIO183 and in muscle physiology, what kind of adaptation do you think could be happening at the cellular level between these 2 individuals?

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
