Dialysis Tubing Post-Lab - Kate Turner | Library

Instructions

Do not start this until we do the lab in class. You can talk to other students but you should write your own answers. Be sure to use the class data for your post lab questions. This is graded on correctness.

Some of the questions ask you to include vocabulary in your answers. Here are examples of vocabulary that I might be looking for in your answers - high/low concentration, hyper/hypotonic, passive transport, simple diffusion, osmosis, dynamic equilibrium, etc.
