In facilitated diffusion, particles are moving through a _________ _______ from high to low concentration.

(a)  

In osmosis, water will move from

• high water to low water concentration

• low water to high water concentration

• cells will burst or swell when put into solution with less solute (ex: freshwater)

• no change because solute concentration is equal
