The movement of molecules from high concentration to low concentration

Question 18

What is osmosis?

Answer 18

The diffusion of water across a selectively permeable membrane

Question 19

Define hypotonic solution.

Answer 19

Lower solute concentration than inside the cell, water moves into the cell
