answer the following questions
Questions 1) Plot the OD600 readings and cell concentration for each time point on a scatterplot with a line connecting the points. Have the measured data (OD600 and cell concentration) on the y-axis against the time on the x-axis using Excel (or other computer based data/graphing program). It is helpful to set the y-axis on a log scale for the cell concentration measurements. 2) Can you...

Procedure: You will follow the growth of E. coli over the course of the period (3 hrs) by making direct counts of the bacterial suspension by measuring the turbidity of a sample at a given time with a spectrophotometer. The data obtained from the direct counts will be used to plot a partial growth curve. Summary: Turbidity Counts with the Spectrophotometer to measure absorbance at 600. Direct Counts...

p. If you accidentally forgot to inoculate your organism in an OF-glucose tube with oil, and only had one yellow “no oil” tube, what type of carbohydrate catabolism would describe that organism (fermenter, oxidative, neither)? Explain your answer. q. What are two other results from the OF-glucose tubes other than their type of carbohydrate catabolism? r. How can organisms that don't use starch grow on a starch agar plate? Carbohydrate Catabolism...
