Review Sheet Results Describe two variables that affect the rate of diffusion. Your answer: The size of material and the concentration of gradient are two variables that affect the rate of diffusion. 1 Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? Your answer: The urea was not able to diffuse through the 20 MWCO membrane because the urea was too big to pass through the pores. 2 Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction? Your answer: The Glucose diffused through the 200MWCO membrane, while there was no diffusion of albumin. 3 Put the following in order from smallest to largest molecular weight: glucose, sodium chloride, albumin, and urea. Your answer: sodium chloride, urea, glucose, albumin. 4
