Question

label the image to review the components of a compound light microscope.
labels ①
drop zones ← reset all
coarse focus
objective lens
stage adjustment
base

Explanation:

To label the compound light microscope components:

1. The topmost drop zone (pointing to the knobs on the eyepiece arm) is for "Coarse focus" (used for initial focusing).
2. The next drop zone (pointing to the eyepiece - objective lens area) is for "Objective lens" (lenses near the stage for magnification).
3. The third drop zone (pointing to the stage adjustment area) is for "Stage adjustment" (controls stage movement).
4. The fourth drop zone (pointing to the base - like the lower, stable part) is for "Base" (supports the microscope).
5. The right - side upper drop zone (pointing to the main body's vertical part) is for "Base" (or the main support, but more accurately, the "Base" is the bottom, and the vertical part is the "Arm", but from the labels given, "Base" fits the lower vertical/stable part here).
6. The right - side lower drop zone (pointing to the stage) could be related to stage, but from the labels, the stage adjustment is for stage movement, and the stage itself might be implied, but with the given labels, we match as above.

Answer:

1. Top drop zone: Coarse focus
2. Second drop zone: Objective lens
3. Third drop zone: Stage adjustment
4. Fourth drop zone: Base
5. Right upper drop zone: Base (or the main support structure, matching the label)
6. Right lower drop zone: (If considering stage, but with given labels, the stage adjustment is for stage movement, so the stage - related drop zone would correspond to stage adjustment's function area, but with the labels, we assign as per the above steps.)

(Note: The exact labeling depends on the standard compound light microscope component positions. Typically, the coarse focus knobs are on the eyepiece arm, objective lenses are near the revolving nosepiece above the stage, stage adjustment controls stage movement, and the base is the bottom - most stable part. The right - side parts: the vertical part is the arm, but if "Base" is a label, it might refer to the lower vertical/stable section. The stage is the platform for the slide, and stage adjustment moves it.)
