The surface area to volume ratio determines the rate of transfer across the cell membrane. what has the best transfer rate?
A: Smaller cells with a high surface area to volume ratio have the best transfer rates
B: Medium sized cells are the best for transfer rates

The answer to this will be from your lab notes/procedure. it would be best to ask another student who participated in the lab as we do not know what was done, what enzyme or if the temperature is celsius or fahrenheit. if i were to guess though i'd say the rate stopped due to enzyme denturing at high temperature

The  correct answer should be a waste

The best way to tell its true color is to look at the minerals streak
