Using the given information, the most suitable choice would be the third option. This is because the students are trying to see the effect of temperature on aerobic respiration in earthworms, making this choice the most suitable. Hope this helps!

What is the primary reason that a hot spring will kill a fishplaced
Leto [7]

Answer: E.) The high temperatures denature (destroy) most of the

fish's enzymes, but the bacteria have enzymes adapted to

these temperatures.

Answer:

Explanation:

Extreme temperature can damage the enzymes and they will no longer remain active. This can causes the denaturation of enzymes. Certain species of bacteria are thermophiles, that is bacterial species can live in the environment, which exhibit temperature higher than normal.

The fish enzymes may not be able to sustain in the high temperature and the fish will die but if the bacteria belong to the thermophile strain then the bacteria will hey adapted to the high temperatures of hot spring.

During intense exercise, the muscle cells require constant supply of ATPs but the supply of oxygen is low. In that case - the mu
larisa [96]

Answer:

Aerobic to lactic acid fermentation pathway

Explanation:

ATP, which is the usable form of energy in living cells, is obtained via a process called RESPIRATION. However, aerobic respiration requires a constant supply of oxygen to occur. Hence, during an intense exercise where the supply of oxygen is low, the muscle cell has to switch from the respiration pathway that requires oxygen to one that doesn't.

Fermentation is a kind of cellular respiration that does not require oxygen to occur. In the muscle cells of animals (humans inclusive), lactic acid is the product of the fermentation process, hence, it is called LACTIC ACID FERMENTATION. This means that the muscle cells, in a low supply of oxygen, will switch from AEROBIC to LACTIC ACID fermentation pathway.
