What happens in osmosis?

Question

What happens in osmosis?

A. Water moves through a selectively permeable membrane from an area of low concentration to an area of high concentration.

B. Sodium ions move through a selectively permeable membrane from an area of high concentration to an area of low concentration.

C. Water is pumped through a transporter protein to get from the inside of the cell to the outside.

D. Water moves through a selectively permeable membrane from an area of high concentration to an area of low concentration.

E. Chloride ions move through a selectively permeable membrane from an area of low concentration to an area of high concentration.

Answer 1

A. Water moves through a selectively permeable membrane from an area of low concentration to an area of high concentration.

Remember osmosis is the movement of water. It is a movement towards places of higher concentration. Imagine water wanting to dilute the high concentration of solute.  

Answer 2

The answer is A! :) Thanks for choosing me as your best answer. :)

If you do, I will send you an email LOL :)

Answer 3

A.

D is active transport.

Answer 4

D

The movement of water across a membrane that is freely permeable to water but not to solutes (dissolved substances), from a region of low solute concentration to one where the solute concentration is higher.

Answer 5

The answer is D. The biggest example of this is the transport of water inside the plant. If water would have moved from a region of low to high concentration, all desert plants would have "DIED of THIRST". So there you have it!
