1 cannot reproduce outside a host cell.
2 can be treated with antibiotics.
3 perform metabolic processes on their own.
4 have a cellular structure.

Answer 1

Viruses are often considered non-living entities primarily because of the following reason:

1. Cannot reproduce outside a host cell - Viruses rely on living host cells to replicate and reproduce. They do not have the machinery necessary for metabolism or reproduction on their own.

The other statements are not accurate in the context of why viruses are considered non-living:

2. Can be treated with antibiotics - This is incorrect; antibiotics are not effective against viruses. They are designed to target bacterial infections.

3. Perform metabolic processes on their own - Viruses do not perform any metabolic processes independently; they require a host cell to carry out any form of biological activity.

4. Have a cellular structure - Viruses do not have a cellular structure; they are composed of genetic material encased in a protein coat and, in some cases, an envelope.

So, the main reason why viruses are considered non-living is that they cannot reproduce outside a host cell.
