Cells Review

Kevin got his wisdom teeth removed and his mouth is swollen so he rinses his mouth out with saltwater. Why does this help?

• Saltwater is hypertonic which releases water

• Saltwater is hypotonic which releases water

• Saltwater is isotonic which absorbs water

• Saltwater is hypertonic which takes in water

The cell membrane is known as a fluid mosaic model composed of proteins and lipids. What is the job of the proteins?

• To block substances from crossing the cell membrane

• To allow substances to cross via active transport

• To feed the cell membrane

• To allow substances to pass via osmosis
