A colony of e coli bacteria asexually reproduce every 20 minutes. If the colony begins with 10 individuals how many individuals will be in the colony after 1 hour?

80 E.coli bacteria are produced in 1 hour.

Explanation:

These bacteria reproduce asexually such as binary fission. In binary fission, the body of organisms is divided into two equal parts and each part becomes a new organism. They have the ability to reproduce after every 20 minutes. In the beginning there are 10 E.coli bacteria. So in 20 minutes, 10 individual becomes 20, in another 20 minutes the 20 bacteria becomes 40 and the last 20 minutes the 40 bacteria reproduce and reach the population to 80 bacteria.
