the concentration of solutes is equal on both sides of a membrane, resulting in no net movement of water across the membrane.

Question 5

hyperosmotic

Answer 5

the concentration of solutes is higher inside the cell, causing water molecules to move from the side with lower solute concentration to the side with higher solute concentration.

Question 6

hyposmotic

Answer 6

the concentration of solutes is lower inside of the cell, causing water molecules to move from the side with higher solute concentration to the side with lower solute concentration
