7. what are the two parts used to carry the microscope?
8. what is the purpose of the coverslip?
9. what is the objective lens used to locate the specimen and first focus?
10. what are the chemicals called that are sometimes used to make the specimens visible?
11. what should you do if the high power objective lens touches or breaks the coverslip?

Explanation:

1. When turning the high - power objective into place, remember to move slowly to avoid crashing into the slide.
2. When using the coarse adjustment, always remember to use it only on low - power magnification to avoid crashing the objective into the slide.
3. Adjust the diaphragm when you need to control the amount of light passing through the specimen, such as when the image is too bright or too dark.
4. When handling microscope slides, always remember to hold them by the edges to avoid getting fingerprints on the glass surface which can affect the view.
5. The purpose of the stage clips is to hold the slide in place on the stage of the microscope.
6. In terms of your eyes, you should try to learn to keep both eyes open while using the microscope to avoid eye strain.
7. The two parts used to carry the microscope are the arm and the base.
8. The purpose of the coverslip is to protect the specimen and the objective lens, and also to flatten the specimen for better viewing.
9. The objective lens used to locate the specimen and first focus is the low - power objective lens.
10. The chemicals sometimes used to make the specimens visible are called stains.
11. If the high - power objective lens touches or breaks the coverslip, immediately stop using the high - power objective, lower the stage, and check for damage to the slide and objective lens.
