2. How can diversity within an ecosystem be compromised? by regulating human activity within an ecosystem
by building structures on natural habitat areas
by helping to maintain habitats that have been disturbed
O by leaving the ecosystem alone to fend for itself

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

Due to the amount of pressure

The answer is one amu.
