Why are latent viruses so dangerous?

Why are latent viruses so dangerous? Latent viruses don’t cause symptoms immediately. They replicate without damaging the host cell. By the time the symptoms appear, the virus is has been replicating for a period of time.

What are the two ways that bacteria can cause harm to your body?

What are the two ways that bacteria can cause harm to your body? Bacteria can make you sick by damaging tissue. Bacteria can make you sick by releasing toxins.

How does bacterial resistance happen?

How does bacterial resistance happen? Bacteria that have mutated survive an antibiotic. The mutated bacteria reproduces and increases in number. When the antibiotic is added again, the mutated bacteria survives. The antibiotic no longer kills the bacteria because the mutated bacteria is resistant.

How are bacteria shaped?

How are bacteria shaped? Bacteria can be round or sphere-shaped, rod-shaped, or spiral- shaped.

Explain the difference between active and latent viruses.

Explain the difference between active and latent viruses. The active virus causes the cell to make new viruses and, in the process, destroys the cell. Latent viruses are in the cell but do not immediately destroy the cell or make new viruses.
