Please do Part #3.
Prepare two separate graphs of Escherichia coli and Staphylococcus aureus using the data in Table.
Plot all the data for each organism on a separate graph. •Log of cells/mL on the y-axis and Time (min) on the x-axis. •Include a title, labeled x-axis, labeled y-axis for each of your graphs.•If you plot your data by hand, make sure you choose values on your x-axis that appropriately use the entire graph paper so that you can see the growth phases clearly. Set up your graph so every bold vertical (grid line) represents 20 minutes is a good place to start. c. Calculate generation time for each organism using the graphic method in the space provided on the graph paper. •Draw a “best-fit” line that best represents the log phase data only. You will connect the dots as best you can but will have to balance some points above the line and some below. The line must be one straight line and cannot bend from point to point and cannot use lag or stationary phase data.•Use the “best-fit” line to calculate generation time using the instructions provided in this manual and Figure 1. Biology 158.9 d. Calculate generation time for each organism using the equation method (page 8.3) using the space provided on the graph paper.
