What characteristic of viruses distinguishes them from cells? They lack an independent metabolism. Their traits do not evolve in response to selection pressures. They are not separated from their environments. They do not have hereditary material.

The correct answer is "They lack an independent metabolism"

Explanation:

Viruses are usually active/alive in a living environment and become inactive in non-living environment; these is because they rely on the metabolic activities of the invaded living environment/cell. This property is a sharp contrast to normal living cells that are able to metabolize different substances independently using several organelles.
