Answer:
A. coarse adjustment knob
(Coarse Adjustment Knob)- The coarse adjustment knob located on the arm of the
microscope moves the stage up and down to bring the specimen into focus. The gearing
mechanism of the adjustment produces a large vertical movement of the stage with only a
partial revolution of the knob. Because of this, the coarse adjustment should only be used
with low power (4X and 10X objectives) and never with the high power lenses (40X and
100X).
