🔍 Step-by-step Solution:

We are given 13 labeled parts in the key, and we need to match them correctly to the blank boxes on the diagram. Let’s identify each part based on its location and function.

#### 📌 Key Parts:
1. Eye Piece (Ocular Lens) – The lens you look through at the top.
2. Coarse Adjustment Knob – Larger knob used to move the stage up/down quickly.
3. Fine Adjustment Knob – Smaller knob for precise focusing.
4. Arm – The curved support connecting the base to the head.
5. Stage – The flat platform where the slide is placed.
6. Stage Clip – Clips that hold the slide in place on the stage.
7. Base – The bottom part that supports the microscope.
8. Body Tube – The tube connecting the eyepiece to the objective lenses.
9. Revolving Nosepiece – The rotating part holding the objective lenses.
10. High Power Objective Lens – The larger objective lens (usually 40x).
11. Low Power (Scanning) Objective – The smallest objective lens (usually 4x).
12. Diaphragm – The adjustable opening under the stage that controls light.
13. Light Source – The light at the bottom that illuminates the specimen.

✔ Now, let's label the diagram:

We’ll go from top to bottom, following the lines.

#### 🔹 Top of the Microscope:
- Topmost black cylinder → 1. Eye Piece (Ocular Lens)

#### 🔹 Right side of the head:
- Large knob near the eyepiece → 2. Coarse Adjustment Knob
- Smaller knob below it → 3. Fine Adjustment Knob

#### 🔹 Connecting the head to the base:
- Curved metal support → 4. Arm

#### 🔹 Stage area:
- Flat platform → 5. Stage
- Small clips on the stage → 6. Stage Clip
- Below the stage, circular opening → 12. Diaphragm
- Bottom of the microscope → 7. Base

#### 🔹 Body Tube & Nosepiece:
- Tube connecting eyepiece to objectives → 8. Body Tube
- Rotating part with lenses → 9. Revolving Nosepiece
- Larger objective lens → 10. High Power Objective Lens
- Smaller objective lens → 11. Low Power (Scanning) Objective

#### 🔹 Bottom:
- Light source under the stage → 13. Light Source

🖼️ Diagram Labeling (by position):

Assuming the lines point as follows:

- Top line pointing to eyepiece: Eye Piece (Ocular Lens)
- Line pointing to large knob on right: Coarse Adjustment Knob
- Line pointing to small knob below it: Fine Adjustment Knob
- Line pointing to arm: Arm
- Line pointing to stage: Stage
- Line pointing to stage clips: Stage Clip
- Line pointing to base: Base
- Line pointing to body tube: Body Tube
- Line pointing to revolving nosepiece: Revolving Nosepiece
- Line pointing to high power lens: High Power Objective Lens
- Line pointing to low power lens: Low Power (Scanning) Objective
- Line pointing to diaphragm: Diaphragm
- Line pointing to light source: Light Source
