Bacteria divide at a constant time interval called the
a. growth rate
b. exponential rate
c. log phase
d. growth time
e. generation time

e. generation time

Explanation:

The generation time is the time that is required by the bacterial cell or cell of the any other organism required to be doubled in number during a specified or constant period of time. The generation time can vary in different organisms.

For example, the E.coli cell divides in every 20 minutes, hence, the generation time of the E.coli is 20 minutes and for the Staphylococcus aureus it is seen as 30 minutes.

i am going to guess that it is co2.

the correct answer is:

a population changes in response to a change in the environment.
