Suppose two students were experimenting with yeast to study cellular respiration. One student found glucose to be the most efficiently consumed sugar by yeast, whereas the other student found maltose to be the most efficiently consumed sugar by yeast. Which of the following could explain the results? A. Organisms have varying optimal conditions at which they work the best. The students may have used different temperatures or pH levels for their individual experiments. B. Different organisms process food sources differently due to the availability of food and other environmental conditions. The students may have used different yeast strains. C. Neither of the two answer choices could explain the results. D. Either of the two answer choices could explain
