- Two solutions are separated by a semipermeable membrane that is permeable only to water. The two solutions are: Solution A = 150 mM KCl Solution B = 150 mM Angiotensin (a 7 amino acid polypeptide) Which of the following would best explain the net movement in this situation? - water will move from the KCl side to Angiotensin side - water will move from Angiotensin side to KCl side - The Cl- ion will move to the angiotensin side until there is 75 mM Cl- on each side - Since Angiotensin is not an ion, it can move through the membrane - There is no net water movement as the concentrations are the same on both sidesarrow_forwardSevere vomiting and diarrhea cause a loss of water and solutes from extracellular fluids. If the person was given only water, what effect would this have on the solute concentration of the extracellular fluids? Would osmosis results in water entering or leaving cells?arrow_forwardThe concentration of ______ is higher in the intracellular fluid than in fluid surrounding the cell. A K+ B Ca+2 C Na+arrow_forward
- Make a chart comparing the composition of the intracellular fluid and extracellular fluid.arrow_forwardA dehydrated runner drinks a lot of water after a race. His cells become rehydrated after drinking water because (a) The bloodstream is hypotonic compared to the contents of the digestive tract. (b) The contents of the digestive tract are hypotonic to the bloodstream. (c) The contents of the bloodstream and digestive tract are isotonic to each other. (d) Water will diffuse from a low concentration to a high concentration. (e) The contents of the digestive tract are hypertonic to the bloodstream. Explain your answerarrow_forwardBlood volume must be restored in a person who has lost large amounts of blood due to serious injury. This is often accomplished by infusing isotonic NaCl solution into the blood. Why is this more effective than infusing an isoosmotic solution of a penetrating solute, such as urea?arrow_forward
