Question

A red blood cells is taken from the body and placed in a beaker containing a hypertonic solution. From this information you KNOW that: A) The solute concentration is significantly higher in the solution than it is in the cell causing water to enter the cell. B) There solute concentration of the solution is lower than the solute concentration within the cell, which causes water to exit the cell. C) The rate of water movement into the cell is equal to the rate of water movement out of the cell. D) The solutes found within the red blood cell are incapable of exiting the plasma membrane. E) None of the above. Which of the following are nitrogenous bases of the purine type? A) uracil and cytosine B) thymine and uracil C) guanine and adenine D) adenine and thymine E) cytosine and guanine

Explanation / Answer

22. e. None of above. The correct answer is that the solute concentration of the solution will be higher and hence water will exit the cell leading to shrinking of RBC.

23. C. Guanine and adenine. Purines are double ring nitrogenous bases.
