6. Under what conditions is water actively transported across a membrane? A. Only from high osmotic pressure to low osmotic pressure B. Only from low osmotic pressure to high osmotic pressure C. Only mammals have evolved the capacity for active transport of water in the kidney D. Many vertebrates have aquaporins that can actively transport water E. None - water always moves by passive transport 7. You are studying two animals from the central Atlantic Ocean, a cnidarian and a...

Intravenous, or IV, solutions used in medicine must exert the same osmotic pressure as blood to prevent a net flow of water into or out of the blood cells. The proper concentration for an intravenous NaCl solution is 0.90 g NaCl per 100. mL of solution (sometimes referred to as 0.90% m/v). If the van't Hoff factor of NaCl is ?=1.8, what is the osmotic pressure of blood at body temperature, 37 ∘C?
