Unit 9 Quiz Review

Viruses are...

• prokaryotic
• eukaryotic
• non-living
• endospores

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

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

What happens in the lytic cycle?

• 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 type of plant that grows in the desert

What is the capsid of the virus?

• Nucleic acid core
• Lipid membrane
• Carbohydrate coating
• Protein shell
