13. Arm (again, for reference in carrying)
14. Base (again, for reference in carrying)

Step2: Answering questions about microscope use

1. Low - power

Starting with low - power objective helps in finding the specimen easily as it has a wider field of view.

1. Fine - adjustment

High - power objectives have a very shallow depth of field, so only the fine - adjustment knob should be used to avoid crashing the objective into the slide.

1. Compound light

Compound light microscopes are commonly used in science classes to view small specimens.
