Viruses

What do viruses need to reproduce?

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

True or False
The flu is caused by a virus.

• true
• false

Antibiotics kill viruses

• True
• False

Which viral life cycle kills its host cell by lysing?

• lytic
• mitosis
• lysogenic
• S phase

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

• lytic
• mitosis
• lysogenic
• S phase

What happens in the lytic cyle?

• Virus goes in and leaves the host cell
• Virus quickly kills the host cell
• Virus sleeps inside of the host cell
• Virus stay dormant for a long time

What happens in the lysogenic cycle? 

• Virus goes in and leaves the host cell
• Virus quickly kills the host cell
• Virus inject the nucleic acid into the host cell, and the nucleic acid integrates into the host cell DNA, and stay dormant for a long time
• Bacteria injects DNA into a host cell

What process is this?

• phagocytosis
• lytic cycle
• lysogenic cycle
• formation of antibodies

What is shown here?

• Lysogenic Cycle
• Lytic Cycle
• Binary Fission
• Conjugation

A pathogen.........

• makes proteins
• causes infection or disease
• is made of cells
• is a living thing
