Order the events that take place when a virus attacks!

• Virus uses key to attach to the lock on a host cell

• Cell begins to make copies of the virus's genetic material

• New viruses erupt from the cell to attack other cells

• New virus particles are assembled

• Virus enters the cell and takes over cell

Joe was diagnosed with strep by his doctor. Should the doctor prescribe antibiotics to help treat Joe?

• No, strep is a viral infection and antibiotics will be ineffective.

• Yes, strep is a viral infection and antibiotics will be effective.

• No, strep is a bacterial infection and antibiotics will be ineffective.

• Yes, strep is a bacterial infection and antibiotics will be effective.

How does antigenic shift differ from antigenic drift?

• Antigenic shift involves minor changes in the virus, while antigenic drift involves major changes.

• Antigenic drift is a gradual change in the virus, while antigenic shift is a sudden and major change.

• Antigenic shift only occurs in animal viruses, while antigenic drift occurs in human viruses.

• Antigenic shift and antigenic drift are two terms for the same phenomenon.

Why is antigenic shift a concern for public health?

• It only occurs in non-contagious viruses.

• It only affects animals and does not pose a risk to human health.

• It can lead to the emergence of new strains of viruses that can cause pandemics.

• It can be easily prevented through vaccination.

What is the main difference between viruses and bacteria?

• Viruses can only cause diseases, while bacteria can have beneficial effects

• Viruses are living organisms, while bacteria are not
