antibiotics are medicines that stop the growth and reproduction of bacteria
virus is a strand of DNA or RNA surrounded by a layer of protein that can infect and replicate in a host cell.

host cell 9. Viruses are not considered living things; they can replicate but must rely on a living organism to do so. The cell that the virus attaches to is called the ______.
viral Antibiotics do not work against _________infections
communicable diseases are also call infectious diseases
pathogens Communicable diseases are caused by _________________ that can be transmitted from one person to another.
