Questions:

Question 1 _ Avery thin, hollow filament, 10 um long and 0.1 pm in diameter, is placed on a wet microscope slide. A dye is introduced into the water. The size of the dye molecules are such that they are just able to fit within the hollow filament. This allows the dye molecules to travel along it but all other movement is negligible. The moment at which the dye first encounters one end of the filament is noted. Which equation governs the progress of the dye through the filament? (g, and pjare the mean square distances traveled in time t, and D is the diffusion coefficient of the dye molecules in the water.) OE=8Dt =20t 15:=6Dt =4Dt Question 2 Only one of the statements below is correct; which one? Q A red blood cell placed in a hypotonic solution will shrink. O A red blood cell placed in a hypertonic solution will swell. O A red blood cell membrane will prevent diffusion of glycerol into the cell. 0 Two solutions are isosmotic when they have the same osmotic pressure
