<h2>Answer is option "1"</h2>
Explanation:
- Infections are not plants, creatures, or microorganisms, however, they are the quintessential parasites of the living realms. Despite the fact that they may appear living organisms as a result of their gigantic regenerative capacities, infections are not living organisms in the exacting feeling of the word.
- Without a host cell, infections can't complete their life-continuing capacities or recreate. Infections can't produce or store vitality as adenosine triphosphate (ATP), however, need to determine their vitality, and all other metabolic capacities, from the host cell.
- Hence, the right answer is option 1 "viruses are not capable of metabolic activity on their own; they must have a host cell to reproduce."

The </span>hypothalamus<span> in the brain, is responsible for monitoring the body temperature. The hypothalamus causes the body to react differently when the body is too hot or if the temperature gets too cold.</span> <span>The normal body temperature is 37'. The hypothalamus triggers the receptors such as sweat glands and body hair muscles in the body.The sweat glands open up when the body is too hot and secrets sweat until the temperature is regulated again. Similarly in cold conditions the body hair muscles pull the hair upright because standing hair absorbs more heat until the falling body temperature returns to normal.</span>
