​

Answer 1

Answer:

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

A viral particle 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 referred 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 envelope is present and their mode of replication.
