12/5/2015 11:55 PM A 0/100 Gradebook Calculator -d Periodic Table Question 28 of 30 Mapof Cell membranes are semipermeable, and osmosis is an ongoing process in the body. Differences in osmotic pressure inside and outside a red blood cell can result in crenation (shriveling) or hemolysis (rupture) (a) The diagram below shows three solutions: an isotonic solution, a hypertonic solution, and a hypotonic solution. Place the appropriate red blood cell in each solution. isotonic solution hypertonic solution hypotonic solution (b) Given that blood exerts the same osmotic pressure as a 0.15 M NaCl solution, which of the following could be the contents of the second beaker? 0 O O 0.68 M NaCI solution 0.008 M NaCI solution 0.15 M NaCI solution Previous Give Up & View Solution e Check Answer (0 Next Exit- Hint

Explanation / Answer

a)

first blood cell in hypertonic solution

second in isotonic

third in hypotonic

b)

In hypertonic solution, concentration of solute is higher in solution than in blood cell.

So content of second beaker can be 068 M NACL solution
