Virus and Bacteria Quiz

What is the main difference between a virus and a bacterium?

• Viruses have a cell membrane and a nucleus, while bacteria have a basic structure of DNA covered by an outer protein shell and some fats

• Viruses have cytoplasm and a nucleus, while bacteria have a basic structure of DNA covered by an outer protein shell and some fats

• Viruses have no cytoplasm, nucleus, or anything resembling a cell, while bacteria have a cell membrane and a nucleus

• Viruses have a basic structure of DNA covered by an outer protein shell and some fats, while bacteria have a cell membrane and a nucleus

How do viruses reproduce once they enter a host?

• By forcing the host cell to replicate the virus instead

• By creating a protective shell around the host cell

• By releasing toxins that infect nearby cells

• By absorbing nutrients from the host cell

What is the purpose of a Memory Cell in our body?

• To absorb nutrients from infected cells

• To release toxins to destroy infected cells

• To produce antibodies to fight off viruses

• To store information about the virus and how it was defeated

Why don't antibiotics work on viruses?

• Because viruses are too small for antibiotics to target

• Because viruses have a protective shell that antibiotics cannot penetrate

• Because viruses can quickly adapt to antibiotics

• Because antibiotics are designed to fight bacteria, not viruses

What is the common virus in our body that destroys bacteria?

• Rhinovirus

• Bacteriophage

• HIV virus

• Influenza virus

What is the main structure of a virus?

• Cytoplasm and a nucleus

• Mitochondria and endoplasmic reticulum

• DNA covered by an outer protein shell and some fats

• Cell membrane and a nucleus

How does a virus infect the cells in our bodies?

• By creating a protective shell around the cells

• By hijacking the cells and forcing them to replicate the virus

• By absorbing nutrients from the cells

• By releasing toxins that destroy the cells

What happens to the host cell once it is infected by a virus?

• It releases toxins to destroy nearby cells

• It begins manufacturing an army of the virus until it explodes

• It becomes resistant to other viruses

• It absorbs nutrients from the virus

What is the role of the outer protein shell in a virus?

• To absorb nutrients from the host cell

• To help the virus attach to host cells

• To release toxins that infect nearby cells

• To protect the DNA from external threats

What is the purpose of the fats in a virus?

• To protect the DNA from external threats

• To help the virus attach to host cells

• To help the virus absorb nutrients from the host cell

• To provide energy for the virus to replicate
