To determine:
The values in the table to be made and the way in which the bacterial population increases when a dish of potato salad is left on the kitchen counter after dinner, the reason for the change of increment of rate over time and to plot a graph for the values to be calculated in the table.
Introduction:
Bacteria are group of organisms that are very versatile in the course of their existence and they have a good and an exponential growth. They do not grow at a normal rate. They are found in almost all the realms of the Earth whether it may be as hot as a hot spring or as cold as a glacier.
Given:
The formula for calculating the number of cells in a population is as follows:
Initial number of bacterial cells =
Time (hours) | Number of generations | Number of bacteria |
0 | 10 | |
1 | 2 | 40 |
2 | 4 | 160 |
3 | 8 | 2560 |
4 | 12 | 40960 |
8 | 16 | 653360 |
10 | 20 | 10485760 |
12 | 24 | 167772160 |
