Answer:
Osmosis is the scientific process of transferring fluid between molecules. When molecules move in and out of a cell to achieve the same concentration of something, like salt, on both sides, then osmosis is happening. ... The fluid might go back and forth a few times until both solutions are equally concentrated.
An example of osmosis is when the water leaves the tubules of the kidney in response to the hypertonic fluid surrounding the tubules. Osmosis in the kidneys is a filtration. Osmosis will filter the water molecules and solutes in the kidneys from the plasma to the tubule. The other choices given are not an example of osmosis. The correct answer to this question is A.
