Virus

Needs host cell to reproduce.

• Virus
• Bacteria
• Fungus
• Protozoan

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 does the lytic and lysogenic cycle have in common?

• The host cell dies
• The virus dies
• The virus inserts its genetic information into the host cell
• copies of the virus are immediately released from the host

What process is this?

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

What is shown here?

• Lysogenic Cycle
• Lytic Cycle
• Binary Fission
• Conjugation

This virus attacks the white blood cells (immune cells) of the human body. Eventually, the immune system cannot handle the viral invasion. This makes the body prone to attack from other viruses and bacteria. What is the name of this infectious viral disease?

• AIDS
• Cancer
• Diabetes

Symptoms of HIV do not show up immediately because the virus can 

• stay dormant for years
• mutate quickly 
• stay outside the cell for a long time

Which statement regarding viruses is true?

• a virus can only reproduce inside of a living cell
• viruses do not contain DNA
• viruses are unicellular
• viruses are generally larger than cells

The capsid of a virus protects the virus from the external environment. What structure is this similar to in a plant cell?

• ribosome
• cell membrane
• vacuole
• cell wall

What feature do viruses have in common with animal cells?

• ability to form proteins at the ribosomes
• existence of lipids in cell membranes
• presence of genetic code in nucleic acid
• production of energy by a mitochondrion
