Question

2 multiple choice 1 point suppose you a viewing a slide using the low power (10x) objective lens. which adjustment knob(s) can you safely use when this objective is in place? only the coarse adjustment knob only the fine adjustment knob both the coarse adjustment knob and the fine adjustment knob

Explanation:

When using the low - power (10x) objective lens on a microscope, the coarse adjustment knob can be used to quickly bring the specimen into approximate focus, and then the fine adjustment knob can be used for sharp focusing. The coarse adjustment knob is safe to use with the low - power lens as the working distance (the distance between the lens and the specimen) is relatively large, so there is less risk of crashing the lens into the slide.

Answer:

C. Both the coarse adjustment knob and the fine adjustment knob (assuming the options are labeled A, B, C as "Only the coarse adjustment knob", "Only the fine adjustment knob", "Both the coarse adjustment knob and the fine adjustment knob" respectively)
