Answer:
A) 12 hours approximately
Duplication times vary depending on the microorganism in question.
Step-by-step explanation:
Bacterial growth is the division of a bacterium into two daughter cells in a process called binary fission. Assuming that no case of mutation occurs, the resulting daughter cells will be genetically identical to the original cell. In this way the duplication of the bacterial population takes place. The bacterial population experiences exponential growth.
