Answer:
The correct order starting from next to the object is
1. coverslip
2. objective lens
3. revolving nosepiece
4. body tube
5. body tube
Explanation:
The correct order starting from next to the object is
1. coverslip
2. objective lens
3. revolving nosepiece
4. body tube
5. body tube
A cover slip is a glass that is used to cover the specimen before observing through a microscope. Thus it is the nearest to the object.
Objective lens is the one which is near to the object hence it comes after the coverslip.
Revolving nose piece is a setup to which the objective lenses are attached thus it will come after the objective lens
Body tube is the hollow and tubular structure that forms the upper part of microscope.
While ocular lens also known as eyepiece are the farthest from the object , hence they come at the last.
