Question

You'l calculate growth rates from the graph below. In this experiment, the number of yeast cells in a lab culture was measured over time. Use the graph below, and it's data to answer the following que

Answer 1

To calculate the growth rate from the given graph of yeast cells, you need to determine the slope of the log phase. Select two points within the log phase and use the formula (change in y / change in x) to calculate the growth rate. For example, if you select two points as (4 hours, 5000 cells) and (7 hours, 12000 cells), the growth rate would be 2333.33 cells/hour.

Step-by-step explanation:

The graph provided represents the growth curve of yeast cells over time. The curve can be divided into four phases: lag, log, stationary, and death. To calculate the growth rate, you can determine the slope of the log phase. For example, you can select two points on the graph within the log phase and use the formula (change in y / change in x) to calculate the growth rate.

Let's say you select two points: (4 hours, 5000 cells) and (7 hours, 12000 cells). The change in y is 12000 - 5000 = 7000 cells, and the change in x is 7 - 4 = 3 hours. Therefore, the growth rate is 7000 cells / 3 hours = 2333.33 cells/hour.
