How will solute move when concentration is outside the system is greater than the concentration inside the system

Solute move when concentration is outside the system is greater than the concentration inside the system due to diffusion and Osmosis.

Explanation:

Diffusion is a movement of substance or material from the area where the concentration is higher to the area where concentration is lower. It is a type of passive transport which means requires no energy for the movement of molecules.

The second is Osmosis. Osmosis is a type of movement of molecules from higher to lower region through a semi-permeable membrane.

the index of refraction of the second medium is higher. i just took the test trust me !
