Question

select the correct word(s) using the drop - down list that correctly complete each statement. (not all labels will be used.) 1. when looking through to make observations, the condenser magnifies the image 10x. 2. if the specimen is appearing too dark, the light entering the condenser can be adjusted by opening the diaphragm using the iris diaphragm lever. 3. the coarse adjustment knob is used to get scanning and low - power objectives in focus. 4. the click to select objective provides the greatest magnification, while the scanning objective provides the least magnification. 5. the eyepiece is also called the ocular lens, and it is used to calculate total magnification of an objective lens. 6. scanning and then low - power objectives are used to get a specimen in focus before using high - power. 7. 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. 8. the flat surface that supports the microscope is the base, and it, along with the arm requires one hand on each part to help carry the microscope. 9. when observing the spinal cord in a prepared slide, the low - power magnification would be used to see the largest amount of the specimen in the field of view

Explanation:

1. The answer for the first blank should be "objective lens" (not condenser as condenser doesn't magnify 10x typically for observation).
2. The light - entering the "condenser" can be adjusted by the iris diaphragm lever. This is correct as stated.
3. The coarse adjustment knob is correctly used to get scanning and low - power objectives in focus.
4. The "high - power" objective provides the greatest magnification while the scanning objective provides the least.
5. The eyepiece is also called the ocular lens, which is correct.
6. Scanning and then low - power objectives are used to get a specimen in focus before using high - power, which is correct.
7. If the slide is moving, check that you have secured the slide to the stage using the "stage clips".
8. The flat surface that supports the microscope is the base, and it along with the arm requires one hand on each part to help carry the microscope, which is correct.
9. When observing the spinal cord in a prepared slide, the low - power magnification would be used to see the largest amount of the specimen in the field of view, which is correct.

1. Condenser focuses light, not magnifies 10x for observation. Objective lenses do the magnifying.
2. Iris diaphragm lever controls light entering condenser.
3. Coarse adjustment knob is for initial focusing with low - power objectives.
4. High - power objective gives highest magnification.
5. Eyepiece and ocular lens are the same.
6. Standard procedure to focus with scanning and low - power first.
7. Stage clips hold the slide in place.
8. Base and arm are used for carrying microscope.
9. Low - power shows more of the specimen in the field of view.

Answer:

1. objective lens
2. condenser
3. coarse adjustment knob
4. high - power
5. ocular lens
6. low - power
7. stage clips
8. arm
9. low - power
