Question

jeremy loves looking at all of the different slides of common things. he is excited to view one after the other. he first looked at the \canary feather\ slide under low, medium and then high power. when he was done viewing the slide he quickly pulled the slide out from under the high power objective and moved on to the next slide. what did jeremy do wrong? how should he have removed the slide?
○ he should have moved the body up so he could carefully remove the slide.
○ he should have moved the body down more.
○ he should have left the slide on the stage for the next class to use.
○ he should have used the inclination joint to get a better angle to remove the slide.

Explanation:

To safely remove a slide from under the high - power objective, the body tube (where the objective lenses are attached) should be moved up. This prevents the objective lens from scratching the slide or getting damaged. The other options are incorrect: moving the body down would increase the risk of damage, leaving the slide on the stage is not the correct procedure for removal, and using the inclination joint is for adjusting the angle of the microscope for viewing, not for slide removal.

Answer:

A. He should have moved the body up so he could carefully remove the slide.
