Experiment 8 Exercise 1: Species Interactions: Competition In this exercise you will be evaluating the effect of competition on the population size of two species of microorganisms. Be sure you have read through the readings for Week 8 as well as the introductory information for the Week 8 Experiment. When you are ready to begin,

Experiment 3 Exercise 2: Osmosis – The Movement of Water across a Membrane Before starting, let’s see what you know about the terms hypotonic, isotonic and hypertonic. Examine the diagrams below. Note that the small green circles represent dissolved solutes like salt, glucose, and amino acids. You can assume that the additional space surrounding the

Experiment 3 Exercise 1: Diffusion – Movement of Solutes across a Membrane We will be using dialysis tubing to simulate a semipermeable membrane. This tubing allows small molecules (e.g., water, ions, glucose) to pass while preventing large molecules (e.g., macromolecules like proteins, starch, glycogen) from moving across. Be sure you have read over the suggested
