Problem Set: Did I tell you I just got a Golden Lab?

A. If you take a sample of Red Blood Cells placed in distilled water, and try to look at the sample in the microscope, you will likely see nothing. Why?

B. Which will sediment smaller organelles? - A centrifugation at 3000 g for 5 hours, or one for 10,000 g for 1 hour? Why?
