Bacteria vs Viruses

What do viruses need to reproduce?

• Genetic material

• A host cell

• Bacteria

• Insulin

Answer explanation

Viruses need a host cell to reproduce.

What process is this?

• phagocytosis

• lytic cycle

• lysogenic cycle

• formation of antibodies

Answer explanation

The process depicted is the lysogenic cycle, where the viral DNA integrates into the host cell's genome and remains dormant until triggered to enter the lytic cycle.

Which viral life cycle kills its host cell by lysing (bursting)?

• Lysogenic Cycle

• Lytic Cycle

• Binary Fission

• Conjugation

Answer explanation

The viral life cycle that kills its host cell by lysing (bursting) is the Lytic Cycle.

What helps prevent viral diseases?

• Vaccines

• Antibiotics

• Herbal tea

• Gene Therapy

Answer explanation

Vaccines help prevent viral diseases by stimulating the immune system to produce antibodies that can fight off the virus.
