15. You are given a series of 10 tubes. In the first is placed 9 milliliters of saline. In each of the others is placed 5 mL of saline. One milliliter of serum is added to the first tube. Five milliliters from this tube are transferred to the second tube, and 5 ml are transferred throughout the remaining tubes. Discard the last 5ml transferred. Give the following: a. Tube dilution for tubes 1 and 6 b. The solution dilution for tubes 1,4, and 7 c. The amount of serum present in tube #3 after transfer.
