1. In order, list the lenses in the light path between a specimen viewed with the compound light microscope and its image on the retina of the eye.
2. What happens to contrast and resolving power when the aperture of the condenser (that is, the size of the hole through which light passes before it reaches the specimen) of a compound light microscope is decreased?
3. What happens to the field of view in a compound light microscope when the total magnification is increased?

Microscopy and its characteristics

Explanation:

There are many lenses in the light path between a specimen viewed with the compound light microscope are following: specimen,objective lens,scope, ocular,eye and etc.when the aperature is decreased in compound  light microscope then the contrast will increase and the resolving power is decreased. This is due to the aperature related to the contrast by indirectly proportion relationship.the field of view is decreased in a compund light microscope this is because it will cover much smaller area in a higher level of details as details become better to show the object.

Covalent bond is the correct answer

To kill bacteria from our body especially from stomach
