Answer:
Ans.5
In clinical settings, light microscopes are the most commonly used microscopes. There are two basic types of preparation used to view specimens with a light microscope: wet mounts and fixed specimens. The simplest type of preparation is the wet mount, in which the specimen is placed on the slide in a drop of liquid.
Ans.6
The main function of the cover slip is to keep solid specimens pressed flat, and liquid samples shaped into a flat layer of even thickness. This is necessary because high-resolution microscopes have a very narrow region within which they focus. The cover glass often has several other functions.
Ans.7
To prepare the slide:
1) Place a drop of fluid in the center of the slide.
2) Position sample on liquid, using tweezers.
3) At an angle, place one side of the cover slip against the slide making contact with outer edge of the liquid drop.
4) Lower the cover slowly, avoiding air bubbles.
5) Remove excess water with the paper towel.

Answer:
5. A specimen is an induvisual plant or animal
(in ur case its microcsopic)
we use micro scope to view it.
6. a cover slip is a very thin glass plate in two shapes cirlce and square, which is used to keep the spesimen in between glass slide and a cover slip.
7. first take a glass slide.
- then remove a thin membrane or cellular structure.
- after that, dip the specimen in the dye if said to do.
- then keep the cover slip on the membrane.
- make sure that there are no bubbles, or you wont get the required result.
- then place it under the micro scope.
hope its helpful.
