How do genetic/genomic issues influence individual variation in the response to a specific drug? a. polymorphisms of genes encoding metabolizing enzymes b. age-related loss of alleles within the cells lining the intestinal tract c. genetic-based behavior problems that promote poor adherence to prescribed drug regimens d. single-gene disorders that reduce the function of the kidneys or the liver

Why are small quantities of chlorofluorocarbons so harmful to the ozone layer? a. the chlorofluorocarbons act like ultraviolet radiation causing large amount of ozone to be produced. b. the chlorine from the chlorofluorocarbons reacts with free molecules of oxygen causing a stop in ozone production c. free oxygen atoms can replace the chlorine in chlorine monoxide, releasing a free atom of chlorine which can then recombine with an oxygen atom in ozone, destroying more ozone. d. chlorofluorocarbons absorb ultraviolet radiation, preventing the formation of ozone select the best answer from the choices provided
