Answer 1

Explanation:

Squeeze your finger and place a drop of blood on a slide and cover with the coverslip. (Use a band-aid to prevent infection.) You may wish to view the lab "Preparing a blood smear" for further information on preparing the slide. Place the slide on the microscope stage, and bring into focus on low power (100X).
