**2. What should be used to clean microscope lenses? Why?**

1. Use only cleaning materials specifically designed for optical lenses.  
   - Typically, a **lens cleaning solution** (often isopropyl alcohol based) is used in combination with **clean lens tissue** or a **microfiber cloth**.
2. The reason for using these materials is that microscope lenses have delicate, multi‐coated surfaces.  
   - Abrasive materials or harsh chemicals (such as regular glass cleaner) can damage the coatings or scratch the lens surface.
3. The proper procedure is generally as follows:  
   - First, gently blow off any loose dust with a lens blower.  
   - Then, lightly moisten a clean lens tissue with the lens cleaning solution.  
   - Finally, gently wipe the lens in a circular motion starting from the center and moving outward to prevent streaks and avoid rubbing debris into the surface.

**3. Identify the structures on the image above from the list on the right.**

1. Since there is no image provided here, we need to describe a general approach for identifying microscope parts.  
   - Typically, a diagram of a microscope includes parts such as:  
     - **Ocular (eyepiece):** The lens through which the image is viewed.  
     - **Objective lenses:** Multiple lenses of varying power mounted on a revolving nosepiece.  
     - **Stage:** The flat platform where the slide is placed.  
     - **Illuminator (light source):** Located usually at the base, providing light to view the specimen.  
     - **Arm:** The curved part that supports the microscope tube and connects it to the base.  
     - **Coarse and fine adjustment knobs:** Used to focus the image by moving the stage or the tube.
2. To accurately identify the structures in the image:  
   - Compare the parts visible in the image to the list provided.  
   - Look for distinguishing features such as the location (top for ocular, lower part for stage, etc.) and shape of the components.
3. Without the specific image, a precise matching cannot be done, so confirm each label by checking:  
   - The **ocular lens** is usually the tube through which the observer looks.  
   - The **objective lenses** will be grouped together near the specimen area.  
   - The **stage** is the platform centered below the objective lenses.  
   - The **light source/illuminator** is typically found at the bottom or integrated into the base.

If you have the image and the list of names, use these guidelines to match each structure accordingly.
**2. Cleaning Microscope Lenses:** - Use lens cleaning solution and microfiber cloths. - Avoid abrasive materials to protect the lens coatings. **3. Identifying Microscope Structures:** - Refer to the provided list and compare with the microscope diagram. - Look for parts like ocular lens, objective lenses, stage, and illuminator. - Ensure each part matches its description based on its location and appearance.
