1. After centrifuging the sample, the laboratory scientist removes the serum and places it into a new, labeled tube for further processing. He decides to make the 1:100 dilution by making a serial dilution. He labels his first dilution tube 1:10. He has a 10-mL pipette. How much saline should be put into this first tube to make 10 ml of a 1:10 dilution? Choose the best letter and give a brief explanation A. 11 mL. B. 10 mL C. 9 mL 2. Now that the laboratory scientist has a 1:10 dilution, what dilution should he make next to create a 1:100 dilution? Choose best letter answer and give a brief explanation. A. 1:2
