Which statement best describes how a virus replicates?

• A virus divides into two identical virus particles before infecting the host cell.

• A virus enters a host cell and uses the materials from the host cell to produce new virus particles.

• Multiple virus particles fuse and form a large particle that breaks apart, releasing new virus particles.

• Multiple virus particles break down in component parts, which then reassemble into new copies of the virus.

In a recent study, scientists investigated the effects of microorganisms naturally found in the body. They raised mice in two different environments and compared their immune system functions in response to a bacterial infection. Their data are shown.Which conclusion about the microorganisms naturally found in the body is most likely supported by these data

• All microorganisms are harmful to the body.

• Microorganisms are important in promoting healthy immune systems.

• All bacteria in the body increase the effectiveness of the immune system.

• Bacteria that cause infections decrease the number and variety of immune cells in the body.

Scientists determined the total mass of DNA from a sample of animal cells. The masses of equal number of cells were taken during three different stages of the cell cycle. Stage I contains cells massed during G1 of the cell cycle. Which statement best describes the cells during Stage II?

• The cells have replicated their DNA, but have not completed mitosis and cytokinesis.

• The cells have completed mitosis and cytokinesis without replicating their DNA.

• The cells have replicated their DNA and completed mitosis and cytokinesis.

• The cells have temporarily exited the cell cycle without replicating their DNA.
