Question

I DIDN'T MEAN CELLS, I MEANT VIRUSES.

Are viruses a microscopic form of life capable of living under extreme conditions?

Answer 1

Well, technically viruses are not a form of life since they are unable to replicated extracellularly and lack a metabolism.

Viruses tend to survive if they maintain conditions similar to those organism they infect. For example, a large number of viruses have been observed from Yellowstone's hot springs. These hot springs can range from 158-190 F and have a pH range of about 1-4.

So, yes, viruses are present in extreme conditions because they are suited to infect the organisms in the environment.
