Homework Answers
Answer 1- c) time required for a population to double.
Reason- Generation time is the time that takes a cell to double. It is also called as doubling time. The generation time varies with the different organisms, for example:- The generation time of E. Coli is 20 minutes, i.e it divides at 20 minutes.
