Suppose you have a culture of bacteria, where the density of each bacterium is 2.0 g/cm³. a. If each bacterium is 5µm × 5µm × 20µm in size, find the number of bacteria if their total mass is 30 grams. Recall that 1µm = 10−6 meters. b. Suppose that you learn that the sizes of bacteria range from 4µm × 5µm × 15µmto5µm × 6µm × 25µm. What is the range of the possible number of bacteria making up the total mass of 30 grams?
Suppose that the bacteria in a colony grow unchecked according to the Law of Exponential Change. The colony starts with 1 bacterium and
triples
in number every
12
minutes. How many bacteria will the colony contain at the end of
24
hours?
Suppose a species of bacteria divides once every 20 minutes. You start with a single bacterium on your unrefrigerated ham and cheese sandwich at 8:00 am. Show that when you sit down to lunch at noon, there will be 4096 bacteria on your sandwich.
