A skunk living in the northern part of the United States is exposed to extreme cold and food shortages during the long winter months. Based on the climate, what do you predict the skunk's innate response to these environmental factors will be?


Increase cellular respiration and ATP production

Estivate with a period of dormancy until the warmer weather arrives

Migrate to regions of warmer weather

Slow down its metabolic rate and lower its body temperature

Answer:

Viral reproduction in a host cell.

Slow down its metabolic rate and lower its body temperature

Explanation:

Viral reproduction in a host cell is not associated with the physiological mechanism regulated by timing. The viral reproduction occurs in the host cell whenever the virus enters the host cell. The virus attaches itself to a host cell and injects its genetic material into it. For reproduction, virus use resources of the host cell to make more viruses and spreads in the neighboring cells. This reproduction does not depend on the specific time, it occurs when it penetrates in the host cell. Skunk slow down its metabolic rate and lower its body temperature when there is extreme cold and food shortages during the long winter months
