Answer:
Viruses depend on the host cells that they infect to reproduce. When found outside of host cells, viruses exist as a protein coat or capsid, sometimes enclosed within a membrane.

Answer: viruses are smaller than bacteria they are not even a full cell thy are simply genetic material DNA or RNA packaged inside of a protien coating
Explanation: They need to use another cell structure to reproduce. This means they cant survive unless they are living inside something else (such as person, animal or plant). viruses can only live for a very short time outside other living cells.
