Answer 1

A. It multiplies with a host cell, and cannot be treated with antibiotics.

Step-by-step explanation:

Viruses are surrounded by a protective protein coating; they don't have cell walls that can be attacked by antibiotics like bacteria does. It is because of this that antibiotics don't work on viruses.

Flu viruses and many cold viruses also have a viral envelope, meaning the capsid is covered by two layers of lipids similar to the cell membranes found on organisms. Viruses can't multiply on their own — they must infect the cells of a living creature.
