The diagram shows a container divided into two compartments by a membrane permeable to water but not to starch. Two solutions containing different concentrations of dissolved starch were placed on each side of the membrane. Which of the following describes what will happen to the water level during the process of osmosis?  

• The water level of both sides of the membrane will decrease 

• The water level on the right side of the membrane will increase 

• The water level on the left side of the membrane will increase

• The water level on both sides of the membrane will stay the same 

An animal cell placed in a sugar solution is shown in the diagram. Which statement best describes how osmosis will affect this animal cell?  

• Water will move out of the cell and the cell will shrink

• Water will move into the cell and the cell will expand 

• Sugar will move out of the cell and the cell will expand 

• Sugar will move into the cell and the cell will expand

A paramecium is shown. This paramecium lives in an environment where water is constantly entering the organism. The paramecium uses specialized vacuoles to pump some of the water back into the environment against a concentration gradient. Which of these processes is used to pump extra water out of the paramecium?

• Osmosis

• Diffusion

• Active Transport

• Electron Transport
