Question

in the solution of salt and water, if the concentration of salt molecules is greater outside a cell than inside, the water molecules will.....
A. move into the cell, and the cell will shrival
B. move into the cell, and the cell will burst
C. move out of the cell, and the cell will shrival
D. move outside the cell, and the cell will burst

Answer 1

i will give medal to best answer

Answer 2

plz help me.....!

Answer 3

Well I can give you insight into osmosis and diffusion, and then you'll be able to answer this yourself. In nature, things typically like to reach some sort of equilibrium--in this case, we're talking about concentrations: the concentration of water and of salt.

The concentrations "want" to be the same on both sides of that cell's membrane,
so to reach equilibrium, what are two things which can happen?

Answer 4

Either the salt moves in or the water moves out, but the cell's membrane won't very easily allow the salt to diffuse into the cell.

We'd call the cell membrane "semi-permeable."

The random movement of particles will eventually lead to water being diffused OUT of the cell, then.

oh ok thx, now i get it. :3
