4. Under favorable conditions, bacteria can multiply every 20 minutes. Starting with one bacteria cell, how many bacteria should you expect after 15 hours? Hint: Under favorable conditions, if one bacterium becomes 2 in 20 minutes (1 multiplied by 2), those 2 become 4 in the next 20 minutes, and then those 4 become 8 in the next 20 minutes. That means that 8 bacteria resulted in 1 hour. Now calculate the growth of bacteria for 15 hours.
