you begin your observations using the ____ lens and the ____ adjustment knob.
a midrange - power, fine
b highest - power, fine
c midrange - power, coarse
d lowest - power, coarse

Explanation:

When starting microscope observations, it is standard practice to begin with the lowest - power lens to get an overall view of the specimen and use the coarse adjustment knob to make large - scale focus adjustments. As the lowest - power lens provides a wider field of view and the coarse adjustment knob moves the stage up and down more rapidly for initial focusing.

Answer:

D. lowest - power, coarse
