rjkz [21]

Answer:

a. do not immediately increase in number when placed in a culture

Explanation:

When bacteria placed in a new culture it shows a pattern of growth which is known as sigmoid growth. It has four phases lag, log, stationary, and death.

The lag phase occurs because bacteria do not start dividing immediately just after the placed in the new culture media because bacteria first adapt to the new environment and prepare enzymes needed for metabolizing the new substrate.  

As the bacteria pass this lag phase it starts to divide at an exponential rate. Therefore it is true that most bacteria do not increase in number immediately after placed in a new culture.
