The activity of this kind of virus remains dormant for a long time (not killing the host for months or years)

What is latent virus

200

These are bacteria that break down large chemicals in dead organisms into small chemicals

What are decomposers

200
Bacteria are known as this because the genetic material is not contained in a nucleus
What is prokaryotes
200
A tiny nonliving particle that enters and reproduces in a living cell is this
What is a virus
