3 WWK: Dialysis tubing (aka visking tubing)
a type of semi-permeable membrane tubing used in separation techniques that facilitates the removal or exchange of small molecules from macromolecules in solution based on differential diffusion  a form of passive membrane transport

4 In a group of 3, create a diagram of your model.
