Exercise 3: Membranes

______________________________________________________________________________Response of Single Celled Organisms to Environmental StimuliLiving organisms respond to outside stimuli. Their ability to sense and respond to the localenvironment increases their survival rate. In this exercise, you will design an experiment toexamine the response of an Amoeba to a particular environmental stimulus.31. Choose the stimulus that you would like to test (e.g. temperature, light, salinity, acidity) andrecord it below.32. Formulate hypotheses (H o and H a) about your predictions on how you expect the Amoeba toreact in response to the stimulus. Write your hypotheses in the space provided.33. Decide how to test your hypotheses. Describe your experimental design in the space below:18
