Question

multiple - choice question
why are viruses considered not alive by most scientists?
they cant reproduce without a host
they do not have genetic material
they dont evolve (change over time)

Explanation:

One of the key characteristics of living things is the ability to reproduce independently. Viruses lack the cellular machinery to reproduce on their own and rely on host cells to replicate. Viruses do have genetic material (either DNA or RNA), and they can evolve over time through mutation and natural - selection processes.

Answer:

They can't reproduce without a host
