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
