1. Describe the key structural characteristics that can be used to differentiate microbes in the following categories: archaea, bacteria, protists, fungi, helminths, and viruses.

2. Explain how you would apply "the five I's" and light microscopy techniques to begin a pure culture that likely belongs to the family Bacillaceae before using expensive molecular techniques to identify the species.

3. Describe the key differences between Gram positive and Gram negative bacteria and describe two approaches (one using the light microscope and one using culture media) that might be applied to help determine whether a particular bacterium is Gram negative.

4. Compare and contrast the key structural and genomic characteristics of Papillomaviruses, Influenza viruses, and Coronaviruses.
