when observing a slide under a microscope, begin focusing with the ____ - power objective lens in place
a midrange
b highest
c lowest

Explanation:

When using a microscope, starting with the lowest - power objective lens makes it easier to find the specimen and focus initially. The field of view is larger and the working distance is greater with low - power lenses, reducing the risk of crashing the lens into the slide.

Answer:

C. lowest
