1) All ions are found mainly in the extracellular fluid, except________________.
Calcium
Sodium
All are exceptions.
Chloride
Potassium
None
2) Which one is the correct conclusion for the diffusion acrossa selectively permeable membrane virtual lab?
None
Diffusion occurred with iodine and glucose because theirmolecular movement is less than that of starch.
Diffusion occurred based on molecular size. Iodine and glucoseare much smaller molecules than starch; therefore, they were ableto diffuse.
All are correct.
Diffusion occurred with iodine and glucose because the dialysistubing membrane contained channels for those molecules.
3) Which of the following is mismatched?
Hypertonic solution: Concentration of solution is greater.
All are mismatched.
None
Hypotonic solution: solution is less concentrated Isotonicsolution: concentration of osmotically active solute is the SAME onboth sides of the membrane (osmosis will not occur)
4) Which should be present in order for diffusion to occur?
Both
A concentration difference between the intracellular andextracellular components.
None
A plasma membrane that allows the passage of the molecule.
