Q1. Catalase functions more optimally at body temperature and assume that body temperature will be a little more like standard 37 C during summer, more hydrogen peroxide would be broken down through the summer because of the hightened activity of the enzyme.
Q2. Comparative study of microbial size, using a stage micrometer, requires that you calculate Bacillus subtilis in both the stained and unstained states. Would you expect the measurements to be equivalent in both preparations? If a variation in size is expected, how will you account for this difference?
