Derek is more likely to have constricted blood vessels and would be more likely to suffer from high blood pressure than Aaron.
b
Derek is more likely to have relaxed blood vessels and would be less likely to have heart disease than Aaron.
c
Aaron is more likely to have constricted blood vessels and would be more likely to suffer a heart attack or stroke.

Clara wrote the following hypothesis for an experiment about acidophilic bacteria. bacteria cells will stop dividing in a basic (alkaline) environment because of the high ph. which statement is the best way to restate the hypothesis so that it is more specific? growing acidophilic bacteria in some environments will cause the cells to stop dividing because of ph. if the ph of their environment is changed, acidophilic bacterial cell division will be affected. if the environment of acidophilic bacterial cells becomes alkaline, the bacteria will stop dividing. the more alkaline an environment, the less cell division will occur in bacteria.
