7. Why does the speed of lysing change as the concentration of NaCl approaches isotonicity with the cell? CHOOSE the correct one.

A.The osmotic gradient decreases as the NaCl diffuses from the solution to the inside of the RBCs, until the concentration of NaCl inside and outside of the RBCs is equal.

B.The osmotic gradient decreases as the concentration of water in the NaCl solution approaches the concentration of water inside the RBCs.

C.The osmotic gradient increases as the NaCl diffuses from the solution to the inside of the RBCs, until the concentration of NaCl inside and outside of the RBCs is equal.

D. The osmotic gradient increases as the concentration of water in the NaCl solution approaches the concentration of water inside the RBCs.

Solution

B. The osmotic gradient decreases as the concentration of water in the NaCl solution approaches the concentration of water inside the RBCs.
