Answer :
Diffusion is the movement of molecule from a place of high concentration to a place of low concentration through a semi-permeable membrane.
Osmosis is the movement of molecules from a place of high water concentration to a place of low water concentration through a semi-permeable membrane
So probably the answer is C
Osmosis is the movement of molecules from a place of high water concentration to a place of low water concentration through a semi-permeable membrane
So probably the answer is C
c osmosis for water diffusion for gases. neither use ATP or energy
