Viruses
Viruses are infectious agents that are very diverse in shape, structure, and behavior, and can only replicate themselves when inside the cell of an organism. Once a cell’s nucleus becomes infected with a virus, that infected cell then reproduces identical copies of itself at an alarming rate, with the ultimate goal of taking over the entire system.
Bacteria
A bacterium, singular for bacteria, is a single-celled organism that lives as part of a colony whose numbers can reach into the billions. They are found in almost every environment on earth and can withstand a wide range of conditions and temperatures. Bacteria aren't necessarily harmful to the human system.
