2. Describe one way in which osmosis is similar to simple diffusion and one way in which it is different.
3. Solutes are sometimes measured in milliosmoles. Explain the statement, “Water chases milliosmoles.”
4. The conditions were 9 m M albumin in the left beaker and 10 m M glucose in the right beaker with the 200 MWCO
membrane in place. Explain the results. How well did the results compare with your prediction?

Experiment Results
Predict Question:
Predict Question 1: What effect will increasing the pore size of the filter have on the filtration rate?
Predict Question 2: What will happen if you increase the pressure above the beaker (the driving pressure)?
Stop & Think Questions:
The reason none of the solutes were present in the filtrate was that
What does an increase in the driving pressure correspond to in the body?
