By the way, what is the difference between bacteria and viruses?
Virus possesses distant characteristics from bacteria. The virus has a different DNA, unlike bacteria. And the virus can be living or not living depending on the environment it finds itself in while bacteria is always a living organism.
Oh, so are viruses more harmful to humans than bacteria? Does it mean that a virus is inanimate outside of an organism, and turns into an organism when it enters into an organism?
Yes, they become living organism when found in a living tissue.
