Answer:
Reproduction.
Step-by-step explanation:
One piece of evidence that a virus is non-living is that it cannot reproduce on its own.
Unlike living organisms, viruses require a host cell to replicate and produce more viruses.
This dependence on a host cell for reproduction suggests that viruses are not truly alive, as they lack one of the key characteristics of living things, which is the ability to independently sustain and replicate themselves.
