A student places a cell with an initial 5% salt concentration in a solution with a 50% salt concentration. What is most likely to happen and why?

• Water will move out of the cell because there is more salt outside the cell than inside.

• Water will move out of the cell because there is more water inside the cell than outside.

• Water will enter the cell because there is more water inside the cell than outside.

• Water will enter the cell because there is more water outside the cell than inside.

Which outcome would be most likely if a cell failed to undergo cytoplasmic division during mitosis?

• The result would be one cell with no nucleus

• The result would be two cells without a nucleus

• The result would be two cells where one has no nucleus

• The result would be one cell with two nuclei

Which statement describes the differences between prokaryotic and eukaryotic cells?

• Prokaryotic cells are larger and more mobile.

• Prokaryotic cells have circular DNA and no nucleus
