Answer 2

Explanation:

A virus is the smallest type of parasite to exist, usually ranging from 0.02 to 0.3mewm in size, although some viruses can be as large as 1meum.

a viral partixle or virion contains a single nucleic acid RNA or DNA core surrounded by a protein coat and sometimes enzymes that are required to initiate viral replication.viruses can only replicate within the cells of animals,plants and bacteria and,as such, are reffered to as obligate intracellular parasites.

viruses are not classified according to the illnesses they cause , instead,they are grouped into different families based on whether the nucleic acid is single-or double-stranded,whether a viral envelopeis present and their mode of replication.
