Question

1. if the specimen is appearing too dark, the light entering the (click to select) can be adjusted by opening the diaphragm using the iris diaphragm lever.
2. the (click to select) is used to get scanning and low - power objectives in focus.
3. the (click to select) objective provides the greatest magnification, while the scanning objective provides the least magnification
4. the eyepiece is also called the (click to select), and it is used to calculate total magnification of an objective lens.
5. scanning and then (click to select) objectives are used to get a specimen in focus before using high - power.
6. if the slide is moving as you try to center it in the field of view, check that you have secured the slide to the stage using the (click to select).
7. the flat surface that supports the microscope is the base, and it, along with the (click to select) requires one hand on each part to help carry the microscope.
8. when observing the spinal cord in a prepared slide, the (click to select) magnification would be used to see the largest amount of the specimen in the field of view

Explanation:

1. The light - entering the condenser can be adjusted by the iris diaphragm lever to change specimen brightness.
2. The coarse adjustment knob is used to focus scanning and low - power objectives.
3. The oil immersion objective provides the greatest magnification.
4. The eyepiece is also called the ocular lens and is used in total magnification calculations.
5. Scanning and then low - power objectives are used before high - power to focus the specimen.
6. If the slide moves, check the stage clips which secure the slide.
7. The base and the arm of the microscope require one hand on each for carrying.
8. To see the largest amount of the specimen, the lowest magnification (scanning) should be used.

Answer:

1. condenser
2. coarse adjustment knob
3. oil immersion
4. ocular lens
5. low - power
6. stage clips
7. arm
8. lowest
