The question is: A patient has arrived at the doctor complaining of acute respiratory symptoms (cough, runny nose, fever). The patient explains to the doctor that he was at a concert the night before and shared a water bottle with a friend who had similar symptoms. The doctor tells the patient that he has a virus. a.) What form of replication do you think this virus does use? How do you know? b.) Can the doctor prescribe an antibiotic for this patient? Explain.

Observing Bacteria in Colonies In fresh or saltwater habitats, cyanobacteria will appear (without a microscope) as very small green lines (as can be seen in this video). Observe the following images of cyanobacteria colonies under 100x and 400x magnification with a light microscope: Anabaena sp. 100x magnification Anabaena sp. 400x magnification As you can see, cyanobacteria grow as two different types of cells: those that are photosynthetic (fixing carbon dioxide to make sugars), and heterocysts (that fix nitrogen to make proteins and nucleic acids). Although these cells are genetically identical, each is able to accomplish this via differences in gene expression, a key concept in biology you will continue exploring this quarter. In the 400x magnification image, you should be able to clearly see two…
