a) 5.5% glucose and 0.9% NaCl have the same osmolarity. What is the osmolarity of these solutions? Please show your work. b) If you soak an animal cell that is permeable to both water and glucose in either 5.5% glucose or 0.9% NaCl (both isosmotic solutions), the cell exposed to 5.5% glucose will gain water, while the cell exposed to 0.9% NaCl will not gain water. Predict why this is the case.
What is the independent variable of the experiment?
4. The normal osmolarity and glucose level of plasma are 300mmol/L and 1g/L, respectively. Estimate the difference between the osmotic pressure of the plasma of a diabetic patient, who has a glucose level of 8g/L, and a patient that has a normal glucose level. Provide the result in atmospheres and meters of water. Ignoring possible physiological compensation mechanisms, what would you expect to happen to the body cells? How would the cells compensate if they could?

A phospholipid bilayer separates two chambers. The chambers both contain the same volume of water. The left chamber contains 150 mM of an unknown solute A. Solute B is dissolved in the right chamber also at a concentration of 150 mM. Therefore, the initial osmolarity is the same (isotonic) between the two chambers. However, after a short time, the volume increases substantially in the right chamber. What is the most likely ranking of permeability for the molecules to cause this change? (greater permeability means that the molecule moves first across the membrane)
