A test tube is inoculated with 1 × 10³ cells of a bacterial strain that has a generation time of 30 minutes. The carrying capacity of the test tube for this strain is 6 × 109 cells. What will the bacterial population be after 90 minutes of culturing?

Question

Quizplus · Accepted Answer

In 90 minutes, there are 3 generations (90 minutes / 30 minutes per generation). The population doubles each generation, so after 3 generations, the initial population of 1 × 10^6 cells will have doubled three times: 1 × 10^6 × 2^3 = 8 × 10^6 cells.
