Answer:
The movement of water from an area of high concentration to an area of low concentration is called osmosis.
The movement of other molecules such as smoke or oxygen from an area of high concentration to an area of low concentration is called diffusion.
Explanation:
Osmosis is the process by which water moves from a place with a low concentration of solutes to a place where the concentration of solutes is higher.
The difference in concentration between two media, separated by a semi-permeable membrane, creates a force called osmotic gradient, which drives the water to move to the place of higher concentration to reach equilibrium. Once equilibrium has been reached, the osmotic gradient disappears.
Diffusion occurs when a substance is found in different concentrations in two media, separated by a semi-permeable membrane. The difference in concentration drives the molecules to move from a medium of higher concentration to the place where it is less concentrated, until they balance. The gradient that is generated is the concentration gradient of that substance
Answer:
1. Osmosis
