1. If a cell has an internal concentration of 0.8% salt and is in a solution that has a 0.8% salt concentration, the solution is considered to be __________ and the net water movement will be __________.

a. isotonic, at equilibrium

b. hypotonic, into the cell

c. hypotonic, out of the cell

d. hypertonic, into the cell

e. hypertonic, out of the cell

2. If a cell has an internal concentration of 2% salt and is in a solution that has a 0.8% salt concentration, the solution is considered to be __________ and the net water movement will be __________.

a. isotonic, at equilibrium

b. hypotonic, into the cell

c. hypotonic, out of the cell

d. hypertonic, into the cell

e. hypertonic, out of the cell

3. If a cell has an internal concentration of 0.8% salt and is in a solution that has a 25% salt concentration, the solution is considered to be __________ and the net water movement will be __________.

a. isotonic, at equilibrium

b. hypotonic, into the cell

c. hypotonic, out of the cell

d. hypertonic, into the cell

e. hypertonic, out of the cell

Solution

1) answer is a. isotonic as (osmotic) salt concentration is same at both sides so water will move at equilibrium.

2)answer is b. - the internal concentration of cell is 2% so it is greater than outside solution so the solution is said to be hypotonic and movement will be into the cell to dilute it and try to make the concentartion same.

3)answer is e. the outside concentration is high then internal concentration of cell so the solution is said to be hypertonic and the movement of water will be out of the cell to try to dilute it to attain same concentartion at both sides.
