A virus can be classified by its type of

• mitochondria
• chromosomes
• nucleic acid
• carbohydrates

What do viruses need to reproduce?

• they need genetic material
• They need a host cell
• They need  bacteria
• They need insulin

How does a virus cause a person to develop the common cold?

• invades the host cell to reproduce
• removes energy from the host cell
• produces toxins in the host cell
• protects the host cell from bacteria

A(n) _____ is a virus that enters a bacterial cell.

• endospore
• decomposer
• plasmid
• bacteriophage

Which viral life cycle allows viral genetic material to lay dormant while the host cell reproduces?

• lytic
• mitosis
• lysogenic
• S phase

Which viral life cycle kills its host cell by lysing?

• lytic
• mitosis
• lysogenic
• S phase

The reason that viruses are considered to be nonliving is because

• They are not cellular
• They cannot reproduce on their own
• They cannot make proteins
• all of the above

A capsid is

• a structure that directly causes cell lysis
• the type of virus that attacks bacteria
• the genetic material of a virus
• the protein coat of a virus

Viruses are cells. 

• True 
• False

What happens in the lytic cyle?
