Question

If a red blood cell is placed in a solution that has a greater solute concentration than the cell's interior, what will most likely occur?




A The cell will shrink as water molecules move out of it.
B The cell will swell as water molecules move into it.
C The cell will shrink as solutes move out of it.
D The cell will shrink as solutes move into it.

Answer 1

help me pls

Answer 2

Naturally, the ions are transported towards lower concentration, therefore in this case it would go into the cell, so I'm thinking it should be B.

Answer 3

Students carried out an experiment in which a semipermeable dialysis bag represented a cell membrane. They filled the bag with a 10% starch solution and measured its mass. Then, they placed the bag of starch solution in a large beaker of distilled water.



After one hour, students wiped the dialysis bag dry and measured the mass again. Which statement describes what most likely happened?




A Its mass decreased, because starch flowed out of the bag.
B Its mass increased, because water molecules flowed into the bag.
C Its mass did not change, because water and starch did not flow through the bag.
D Its mass did not change, because starch and water reached equilibrium.

Answer 4

@Iseulde your logic is correct, but the answer you gave is the reverse of what you said.

Answer 5

@Niniguma post only 1 question per thread.

Answer 6

I do really need help from u guys

Answer 7

but salt keeps water in the tissues, as far as I remember...

Answer 8

right, but you placed a cell in a solution with a higher solute concentration.

Answer 9

yep, true :)
the answer to the second question must conform to the same logic then.

Answer 10

A RIGHT
