Q1. Suppose that after washing your hands, you leave ten bacterial cells on a new bar of soap. You next decide to do a plate count of the soap after it was left in the soap dish for 24 hours. You dilute 1 g of the soap 1:10 6 and plate it on standard plate count agar. After 24 hours of incubation, there are 168 colonies. How several bacteria were on the soap? How did they get there?

Q2. Unlike squamous cells, cuboidal and columnar cells have large, open cytoplasms. Which functions of epithelial tissue are supported by having such big cells?
