Bacteria and viruses change the genotype of an organism through mutation. Mutations are heritable changes in DNA and RNA that changes the genes..
Bateria are made of cells APEX~:)
Viruses require a living organism to do anything - most especially to reproduce.

An unicellular organism is an organism that does not have a nucleus. Two types of these organism is bacteria and archaea.
the micro-organism cell includes fungi,protozoa,viruses,bacteria and algae
a simple organism is divided into 5 groupes;viruses,bacteria,protozoa,algea and fungi..
Tapeworms, fleas, leeches, and most viruses, and some bacteria all fall under the label of parasites. Parasites benefit from another organism at that organism's expense.
Parasites are any organism that lives off another organism. They can be anything from ticks and fleas to microscopic bacteria and viruses.
Bacteria are able to reproduce on their own while viruses need a host to "hijack" so they can reproduce. Bacteria have metabolisms, catabolic and anabolic biochemical reactions going on in their cells all the time. Viruses do not. Bacteria can grow in size to a certain extent while viruses do not change in this regard. The definition of living things classify bacteria as a living thing, while viruses are not.
Bacteria metabolize ingested nutrients. Viruses do not do this. Bacteria reproduce by fusion. A virus needs a host to reproduce. Bacteria exchange gases with the environment. A virus does do this. A bacteria is motile in many cases. Flagella. Viruses must depend on the current in solution. As you see viruses do not have any of the markers of living organisms, but some biologists do not fully agree that viruses are not a sort of living organism.
None to my knowledge. Even bacteria are susceptible to infection by viruses.
