What do viruses need to survive and reproduce?
Viruses need a host cell to survive and reproduce. They cannot replicate on their own; instead, they hijack the machinery of host cells to produce more virus particles. Once they have infected a host cell, they use the cell's resources to replicate their genetic material and assemble new virus particles.
Why would it not be advantageous for a virus to kill its host?
It would not be advantageous for a virus to kill its host because if the host dies, the virus would also die since it needs the host to replicate and spread. It is more beneficial for a virus to keep the host alive so it can continue to infect other individuals.
Does a virus need a host cell?
Yes, a virus needs a host cell to replicate and reproduce. Viruses cannot carry out their own metabolic processes or reproduce independently. They rely on infecting a host cell and hijacking its cellular machinery to make new copies of themselves.
Can viruses reproduce with dead or alive cells?
Viruses cannot reproduce on their own because they lack the necessary cellular machinery. They need to infect a living host cell in order to replicate and produce more virus particles. In some cases, viruses can infect and replicate within host cells that are no longer alive, but this is not considered true reproduction.
Why is virus not considered nonliving?
they can not reproduce without a host cell .
