Question 26 Why do viruses need living hosts, such as bacteria or eukaryote cells? a Viruses depend on the host cells that they infect to reproduce/replicate. b Viruses have a cellular structure which never requires a host. c Viruses depend on a host cell because they lack their own DNA or RNA. d The host cell is the source of food for the virus.

Answer 1

The correct answer is a Viruses depend on the host cells that they infect to reproduce/replicate.

Viruses are not considered living organisms and do not have the cellular machinery necessary for replication or metabolism on their own. Instead, they hijack the cellular machinery of a host to reproduce and propagate.
