Question

sufficient amount of water moves into a red blood cell, the membrane will rupture and vent its contents. This process is called hemolysis and is characterized by clarification of the cell suspension. For the following solutions indicate if they are isosmotic with the intracellular fluid of a red blood cell (ass ed blood cell osolarity is 300 mOs). Als idicate if red blod lls would srell or shrink if placed in given solution. Hemolysis (Yes or No) osmolarity(Osm) | Osmolarity (hyper, iso,hypo) Solution onicity (hyper, iso, or hypo) 150 mM NaCl ddH:0 100 mM NaCI 50 mM NaC 300 mM sucrose 150 mM CaC 300 mM urca 900 mM Nac 150 mM NaCI 3D) mM urea Discuss brietly the movement ot water tor each of the solutions and your rationale for the appearance of the red cell suspension.
