Question

Which of the following would be an example of osmosis?

A) the smell of ammonia spreading through the room
B) the shriveling of a small after salt is poured on it
C) water being poured into a glass
D) the absorption of water by a sponge

Answer 1

B) the shriveling of a cell after salt is poured on it

Step-by-step explanation:

During osmosis, water moves from a low concentration to a high concentration. Since the salt is outside the cell membrane, it makes the outside have a higher concentration than the inside of the cell; causing the water to move from the cell and the cell shriveling.

Answer 2

D

Step-by-step explanation:

An example of osmosis occurs when a sugar solution and water, top, are separated by a semipermeable membrane. The solution's large sugar molecules cannot pass through the membrane into the water. Another good example of osmosis would be dipping a sponge into water, because there is a higher concentration outside, so the water goes in and makes the sponge expand
