Q

Why do viruses invade cells

A

Viruses invade cells because they are in active outside of the host (virions), they lack ribosomes needed for metabolisms and they use the raw materials of the host cell to be able to reproduce

Q

What is an endospore

A

An endospore is a bacteria that forms a hard shell because of the lack of food.
