List four ways in which viruses can be similar or differ from each other.

There are a variety of ways by which viruses could be classified, however, including virion size, capsid structure, type of nucleic acid, physical properties, host species, or disease caused.

Explanation:

A virus is made up of a DNA or RNA genome inside a protein shell called a capsid. Some viruses have an external membrane envelope. Viruses are very diverse. They come in different shapes and structures, have different kinds of genomes, and infect different hosts.

Are you talking about bacteria type viruses? because that's what I would assume.

Explanation:

Well, all viruses have a core of genetic material like RNA or DNA.

Viruses can have different families, geonomic makeup, host range and transmission mechanism.

I hope this helped in a way.
