The chemical formula for the major component of palm kernel oil is ch3(ch2)14co2h. the chemical formula for the carbohydrate glucose is c6h12o6. which statement best describes these macromolecules as foods?
a. glucose is a better energy source because it is the only one that can be broken down by living things.
b. palm kernel oil would provide a quicker energy source than glucose because it has more carbon atoms that can be used.
c. glucose is the only one that would provide energy to living things because it is a key product of respiration.
d. palm kernel oil would provide more energy than glucose because it contains more carbon bonds, which release energy when broken.

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

Why do leaves change color in the fall? green pigments break down and no longer mask the color of chlorophyll. chlorophyll breaks down and no longer masks the colors of other pigments. red- and yellow-colored pigments grow and mask green-colored chlorophyll. green-colored chlorophyll breaks down and turns red and yellow.
