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:

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.
