35. The paragraph at the top of the page tells you "Catalase [is] a biological catalyst produced by cells [that] speeds the breakdown of hydrogen peroxide."
Of course, you know that, in general, a catalyst is a substance that facilitates a chemical reaction without being used up as a result of that reaction.
36. Catalase is most active at the temperature of 35 °C. (This is not unexpected, as 35 °C is near the temperature considered to be normal body temperature (37 °C).) The table and the corresponding graph show this to be the case.
Answer:
I think it's
A <u>mass </u>extinction occurs when many species go extinct in a relatively short period of time.
Explanation:
Mass extinction is usually defined as a loss of about three-quarters of all species in existence across the entire Earth over a “short” geological period of time. Hence, I think the answer is correct.
Answer:
there is an association between the number of mitochondria in muscle cells and energy production
Explanation:
Mitochondria generate energy by generating adenosine triphosphate (ATP), which is referred to as the "molecular unit of currency" of the cell since this molecule provides energy for diverse cellular processes
Answer: Prey can avoid predators by minimizing their movement and their presence.
Explanation:
Prey minimize their presence and avoid predators by staying silent, staying in their refuge, and reduce their overall activity levels.
