Biology
I have to do online research on an endangered or impacted species in my area. I chose the spotted dusky salamander. Here are the questions:
1- describe the natural environment of the species in terms of abiotic and biotic factors.
2- describe the biome in which the species lives and the properties of the biome.
3-if humans have altered the natural environment, describe the changes made by humans and their impact on the species.
4-choose from three types of scientific workers (biologists, chemists, and geographer’s) that you think could help solve the problems associated with this species, and explain how they could apply their knowledge.

Ответ:
enzymes loose their form in both unsuitable ph and temprature.
Explanation:
at very high tempratures enzyme molecules denatures due to high speed movements, at low tempratures enzymes works too slow to be useful enough.
low ph solotions contain lot of H+ and high ph solutions have few H+ , and the number of these H+ ions have polar effects on enzymes. some Enzymes like pepsin works perfect in acidic environment ( ph=2) while others might work at high ph or average ph( like Trypsin works well at ph=7).
