The viral capsid is composed of subunits called __________?
What are capsomers?

This is the only characteristic of life that viruses exhibit.
What is reproduction?
300
The semipermeable membrane surrounding a cell and controls what enters and leaves the cell.
What is the cell membrane?
300
This part of a virus structure would include phospholipids.
What is the envelope?
300
Name the replication phase: A virus "connects" to a host cell by special receptors.
What is attachment or adsorption?
300
Name the characteristic of life: Ability to produce new individual organisms
What is reproduce?
300
This component makes up the structure of a cell membrane.
What are phsopholipids?

Name the replication phase: The pieces of a virus are put together in order to be released.
What is assembly?
400
Name the characteristic of life: Internal regulation to maintain a constant, balanced state.
What is maintaining homeostasis?
400
Name the way viruses reproduce.
What is inserting DNA into the host cell?
500

What are ribosomes?
500
A virus that specifically infects a bacterial cell is called _____________?
What is a bacteriophage?
500
