A student made a culture of yeast cells in a test tube by mixing a pinch of dry yeast with
10 mL of distilled water. This test tube was labeled A. The student then took 1 mL of the
resulting solution and placed it in test tube B with 9 mL of distilled water. The student
continued using this method of serial dilution through trial E as shown above in the
picture. Examining the solution in test tube E under a microscope, the student found
, that there were 1,500 yeast cells per milliliter. Which of the following is the concentration
of yeast cells per milliliter in test tube C? –
150,000
