In your own words, describe how scientists classify living things

They classify organisms (living things) so they can get a better understanding of animals and how many variations of animals there are if they didn't we could find a new animal and not even know it there are lots of other reasons to mostly about cittern animals traits and behaviors and what an animal eats and if the food chain is broken what would happen to that animal or how it adapts to its climate.

hope this helps 100% in my own words :)

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
