- 7. Use each of the words hypotonic, hypertonic, and isotonic correctly in separate sentences. 8. The ICF of a red blood cell is approximately 0.3 OsM (osmolar). Explain what will happen to a red blood cell that is placed in each of the following solutions. Complete the following table to predict what will happen to a red blood cell that is placed in each of the following solutions. Is the solute Osmolarity (answer should be a number). What will happen to a red blood cell placed in this solution? Solution non-penetrating Tonicity or penetrating? 0.3 M Glucose 0.3 M NaCl 0.3 M Urea niek ugni fehbnodbolnThe osmolarity of physiological saline solution is 0.30 osmol/L. Assuming that the cell membrane is not permeable to its ions, is a 0.110 M aqueous solution of magnesium sulfate, MgS04, hypertonic, hypotonic or isotonic to red blood cells? If normal red blood cells were suspended in this MgSO4 solution, what would be the expected outcome? |Please order the following types of solute diffusivity from largest to smallest. 1. D pore: Diffusivity of solute in a pore 2.De: Effective diffusivity of solute through a heterogeneous membrane material 3. D AB: Diffusivity of solute in water 4.

- 2. In the following scenarios, describe how water will move. Please describe why, I am having difficulty understanding osmolarity. Sigma represents the reflection coefficient. Thanks for your help!3. Draw and label a diagram that demonstrates the difference between tonicity and osmolarity. Be sure to label the new solutions in each condition, draw the changes (if predicted) in cell shape/volume, and clearly use arrows to indicate the movement of water relative to the cell. Please start with a red blood cell in an isotonic solution (Figure D) and show what happens to cell shape and water movement when NaCl (remember that the membrane is permeable to neither of these ions) (Figure E) or urea (a permeable ion) (Figure F).2. Oral rehydration therapy (ORT) have save the lives of countless children worldwide. This is done by feeding of an electrolyte solution. One property of this solution is that it be isotonic with human blood. a. Isotonic solutions have definitions that it has the same osmotic pressure as 0.92% w/v aqueous solution of NaCl and has a freezing point of -0.52 °C. Show that these two definitions are in reasonably close agreement given that we are using solution concentrations rather than activities b.
