Question

When scientists classify living things, they do not include viruses. This is because viruses
A) cause disease.
B) do not contain DNA.
C) are not made of one or more cells.
D) are much smaller than other organisms.

Answer 1

Because they are much smaller than other organisms

Answer 2

None of the above. Scientists do not consider them as living because viruses remain unactive until they enter a living body which means they remain dead and can only be awakened when they find another body to do the necessary things for survival to them.
