A person with swollen gums rinses his mouth with warm salt water, and the swelling decreases. Which has occurred?

• The swollen gums have absorbed the saltwater solution

• The saltwater solution lowers the temperature in the gums

• The salt in the solution has moved against the concentration gradient

• The water in the gums has moved from a high to a low concentration of water

Which is an example of osmosis?

• potassium ions moving in and out of an animal cell

• carbon dioxide moving into the leaf cells of a plant

• oxygen moving into the bloodstream from the lungs

• water moving into the root cells of a plant

What will most likely be the result if all of the mitochondria are removed from a plant cell?

• It will be unable to carry out respiration

• It will lose water through osmosis

• It will break down the ribosomes in the cell

• It will be unable to photosynthesize
