Which of the following solutions, if you place REd Blod cell in it, will not harm it? Hint: the solution must be Isotonic A. 10.%NaCl Solution B. 5.0% glucose Solution C. 2.5 % glucose Solution D. 0.90%NaCl solution

Step 1
An isotonic solution has the same concentration of solutes as the inside of the red blood cells, which prevents the movement of water in or out of the cells, thus maintaining their shape and function. Show more…

A red blood cell placed in a hypertonic solution will shrink in a process called crenation. A red blood cell placed in a hypotonic solution will swell and potentially burst in a process called hemolysis. To prevent crenation or hemolysis, a cell must be placed in an isotonic solution such as 0.9% (m/v) NaCl or 5.0% (m/v) glucose. This does not mean that a cell has a 5.0% (m/v) glucose concentration; it just means that 5.0% (m/v) glucose will exert the same osmotic pressure as the solution inside the cell, which contains several different solutes. A red blood cell is placed into each of the following solutions. Indicate whether crenation, hemolysis, or neither will occur. Solution A: 3.21% (m/v) NaCl Solution B: 1.65% (m/v) glucose Solution C: distilled H2O Solution D: 6.97% (m/v) glucose Solution E: 5.0% (m/v) glucose and 0.9% (m/v) NaCl Drag each solution to the appropriate bin.
