Passage I
Bacteria reproduce by a process in which a single cell divides into two cells. The average time required for bacteria to divide and their population to double is called the generation time. Table 1 presents the generation time for a variety of bacteria at a given temperature.
Bacterial population growth occurs in a series of distinct steps referred to as a bacterial growth curve. It consists of 4 phases, which reflect changes in the cells' environment and metabolism over time. See Figure 1.
2. The bacterial population increases most rapidly during which of the following phases?
Your Answer is
Correct Answer is G
Explanation
Look at figure 1, in the log phase, the slope of the line segment is the largest, so the growth is the fastest at this time
