When a virus invades a living cell, the virus's genetic material

• takes over many of the cell's functions
• breaks apart
• attaches to the outside of the cell
• sends messages to other viruses

A substance that stimulates the body to produce chemicals that destroy viruses or bacteria is called a 

• poison
• vaccine
• cytoplasm
• toxin

Bacteria are prokaryotes because

• they do not have genetic material
• their genetic material is not inside a cell
• their genetic material is not inside a nucleus
• they have a nucleus filled with genetic material

Which is a characteristic shared by ALL protists?

• cells do not have a nucleus
• cells have a nucleus
• live in dry places
