The reviewers suggested that you think more carefully about your hypothesis and experimental design. For a chemical to make a good cancer treatment, it is not enough that it harms cancer cells. The chemical needs to have a selective effect on cancer cells--that is, it needs to harm cancer cells much more than it harms normal (noncancerous) cells. You decide to run a new experiment to test the hypothesis that the fungus chemical harms cancer cells selectively. In this controlled experiment, you will test both cancer cells and normal cells under identical conditions. What data would support this hypothesis?
