(I gave the image since I don't know if that info is needed to solve this question.)It also gives a follow-up, if you can help here too: You work in a lab as a summer student. One of your tasks is to make sure that there is enough cell culture medium containing antibiotics to grow bacteria. One day you realize that there is only 5 ml of 10% Antibiotic stock solution in the freezer. You decide to use it all to prepare the working culture medium with 0.01% antibiotic. In the lab there is plenty of growth medium without antibiotics. (Note: dilution in medium is like dilution in water). You remember the equation to make dilutions of stock solutions. You usually use this formula to calculate the required volume of a stock solution, but you realize it can apply here as well, even though the unknown is the final volume. So, you make that dilution. Given that each bacterial…FOV measured at 100x total magnification is 400 micrometers. What is the FOV at 40X total magnification? 2. If FOV is 5 mm and the number of cells in FOV is estimated at 35, what is the cell size in mm? In micrometers?

Show your work. (MW of X= 225) b)Determine the volume required (mL) from the stock solution X in (i) to prepare 500 mL of MS medium containing 5 mg/L X. Show your work.The standard curve to determine the amount of betacyanin is shown below. You extracted a red pigment from a beet disc (the mass of a disc is 2 g) using 10 ml of 20% ethanol solution. You measured absorbance of the solution above the beet disc every minute for a total time of 20 minutes. The increase in absorbance was linear during a period of time from 1 min to 10 min. The absorbance at 10 min was 0.8. Calculate the amount of betacyanin extracted from 1g of a beet tissue per minute. Explain your calculations. You can use Excel or a calculator.
