Question 11

Refer to the scenario below, and then answer the following question(s).
As part of your field biology independent study, you visit a small lake with an extremely high salt concentration. Searching with nets and other sampling devices, you find no fish, plants, algae, or any visible signs of life in the lake. Still, you decide to take a few samples of the water back to the lab. You find the sample teeming with very small cells, hundreds of times smaller than a typical human cell. These cells have cell walls, which you analyze chemically and find they are not made of peptidoglycan or cellulose.
