• Endocytosis
• Active transport
• osmosis

Two different solutions are separated by a membrane permeable only to water. How will molecules move?

• solutes will move by dissolving
• water will move by active transport
• solutes will move by osmosis
• water will move by osmosis

Your gums are swollen. How will rinsing with warm salt water help the swelling?

• swollen gums will absorb the salt
• salt lowers the temp
• salt goes against the concentration gradient
• water in the gums has diffused out of the cells

Cells need to bring in molecules to carry out cellular processes. Often, this requires moving the molecules across the cell membrane against the concentration gradient. How do these molecules get into the cell?

• passive transport by diffusion
• active transport using ATP 
• passive transport by osmosis
•  osmosis

The cell membrane of the red blood cell will allow water, oxygen, and carbon dioxide to pass through. Because other substances are blocked from entering, this membrane is called

• perforated
• semi-permeable
• non-conducive
• permeable

 Look at the diagram of a cross-section of a cell membrane below. The cell membrane controls movement of materials into and out of the cell. The following particles are moving from high concentration to low concentration and are using a carrier protein. How would you describe this type of movement across the membrane? 

• simple osmosis
• active transport
• simple diffusion
• facilitated diffusion
