D Using the picture serial dilution scheme and the following information (plate A has 276 colonies, plate B has 298, plate C has 2, and plate D has 30), calculate the average number of colony forming units per mL in the stock tube. Make sure to only use countable plates. Round your answer to the nearest one. Write only the number with any needed commas or decimals. Do not include units.How would you make two-fold serial dilutions such that the last tube is a 1:32 dilution of the original, concentrated material? Assume that you need to have at least 500 µl of each dilution, and you should be able to perform the dilutions in microfuge tubes with a maximum capacity of 1.5 ml.
