Question

the bacterial population did not have a constant growth rate, so it did not exhibit linear growth. the bacterial population exhibited exponential growth. when a population grows exponentially, its growth rate increases as the size of the population increases. on a graph, exponential growth is modeled by a j - shaped curve. bacterial population order the time periods. start with the period during which the population had the highest growth rate. end with the period during which the population had the lowest growth rate. highest growth rate between minutes 150 and 180 between minutes 120 and 150 between minutes 30 and 60 between minutes 60 and 90 between minutes 90 and 120

Explanation:

Step1: Analyze slope of curve for growth rate

The steeper the curve on the population - time graph, the higher the growth rate.

Step2: Compare slopes for time - periods

Between 150 and 180 minutes, the curve is steepest, so it has the highest growth rate. Then, between 120 and 150 minutes, the curve is also quite steep. Next, between 90 and 120 minutes. Then, between 60 and 90 minutes. And between 30 and 60 minutes, the curve is least steep, so it has the lowest growth rate.

Answer:

1. between minutes 150 and 180
2. between minutes 120 and 150
3. between minutes 90 and 120
4. between minutes 60 and 90
5. between minutes 30 and 60
