Why should one put the coverslip very carefully while preparing a mount?

Explanation

### Step-by-Step Solution:

1. **Understanding the Mount Preparation**: When preparing a mount, we place a specimen on a slide and cover it with a coverslip. This is done to protect the specimen and to allow for clear observation under a microscope.

2. **Importance of the Coverslip**: The coverslip serves to flatten the specimen and keep it in place. It also helps in creating a uniform thickness for better light passage when viewing through the microscope.

3. **Air Bubbles Issue**: If the coverslip is not placed carefully, air bubbles can get trapped between the coverslip and the slide. These bubbles can obstruct the view of the specimen.
