Antibiotics
Vaccine

What is the outer protein coat of a virus is called?
(a)
How does a virus attach to a cell?
The protein projections (spikes) on a virus touches the cell's proteins.
By bouncing off of the cell's membrane.
Uses it's fibers to lasso itself to the cell.
Surrounds the cell until it lets it in.
Which occurs during the lysogenic cycle of a virus infection?
Viral genes instruct the host cell to make more viral protein capsids and enzymes needed for viral replication.
The virus produces active, immediate infections.
The virus takes over the cell, makes copies of itself, and usually kills the host cell.
The viral genes become a part of the host cell DNA, so the cell continually makes more copies of the virus.
Viruses can affect which types of organisms? Select TWO correct answers.
Plastic
Animals
Bacteria
Bricks
What is the one thing that eukaryotic cells, prokaryotic cells, and viruses have in common?
(a)
Viruses cause infection by ______________.
Producing toxins that harm the body.
Reproducing independently inside the body.
Forming endospores.
Entering body cells and replicating.
If Andy is feeling symptoms from a virus that he contracted, the virus must be in the cycle.
(a)
In which type of cell cycle(s) does viral DNA become integrated into the host cell's DNA?
Lytic
Lysogenic
Neither lytic nor lysogenic
Lytic and lysogenic
Bacteria reproduce through.
(a)
Increase its size
Synthesize needed oxygen
Obtain nutrients
Reproduce
Bacteria are often beneficial to both organisms and the .
(a)
(a)
Which of the following is TRUE?
Both bacteria and viruses are living things.
Viruses are living things, bacteria are not.
Bacteria are living things, viruses are not.
Neither bacteria or viruses are living things.
What is antibiotic resistance?
An explanation for viruses not being affected by antibiotics.
The ability of bacteria to resist the effects of an antibiotic to which they were once sensitive.
A rare genetic disease that makes it so that your body is resistant to the effects of an antibiotic.
