Q1. The reason was to isolate catalase from starch and measure the rate of activity under different conditions. The laboratory was also conducted in association with a second laboratory that measured the effects of an inhibitor on the enzymes.

Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration were the conditions tested in experiment.

Q2. Spiny species of diatoms are found in both warm subtropical and cool waters. because warm water is less dense then cold water, would you predict any difference between spines of warm water individuals and those of cold water individuals? Why give reason?
