Question

All viruses live ________

• A. Outside the host cell
• B. Independently
• C. Inside the host cell
• D. None of the above

Answer 1

The correct option is B

Explanation of the correct answer:

1. A virus is a tiny, infectious particle that can reproduce only by infecting a host cell.
2. It is inactive and behave like non-living when outside the host.
3. Viruses "commandeer" the host cell and use its resources to make more viruses, basically reprogramming it to become a virus factory.
4. Because they can't reproduce by themselves without a host, viruses are not considered living.
5. Nor do viruses have cells: they're very small, much smaller than the cells of living things, and are basically just packages of nucleic acid and protein.
6. So. all viruses are live when inside the host cell.

Explanation of the incorrect answers:

Option A:

1. Viruses can not multiply without the host cells.
2. Hence, viruses are not independent.

Option C:

1. Viruses are inactive and behave like non-living when outside the host.
2. Hence, they are not live outside the host cell.

Option D:

1. Viruses behave like living by multiplying inside the host cell.
2. Hence, this option is invalid.

Final answer: All viruses live inside the host cell.
