A microbiologist inoculates E. coli into a fresh nutrient broth and records the density of bacteria (# of cells per mL) over time. At first, there is little to no increase in cell number. Then, the population grows rapidly and exponentially. After several hours, growth levels off. The microbiologist adds glucose during this plateau, and cell numbers rise briefly before stabilizing again. A day later, the number of living cells declines even though some nutrients remain. Explain the following (2 points each): Why the cells did not grow immediately after inoculation. Why adding glucose only temporarily increased growth. Why the population eventually declined.
