Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why is it necessary to carefully place the cover slip on top of the specimen on the glass slide? Choose two answers.
A
To prevent air bubbles
B
To prevent you from getting any stain on your hands
C
To make your results more accurate
D
To be able to see the cells
Explanation: 

Detailed explanation-1: -The coverslip protects the specimen, stopping it from drying out. It holds the specimen in place and also protects the objective lens from the stain. It has to be placed carefully onto the specimen to prevent trapping air bubbles beneath it, which would spoil the image you see of the specimen.

Detailed explanation-2: -The slides should not be viewed wet. When viewing any slide with a microscope, a small square or circle of thin glass called a coverslip is placed over the specimen. It protects the microscope and prevents the slide from drying out when it’s being examined.

Detailed explanation-3: -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.

Detailed explanation-4: -In the lab, histologists know that placing cover slips onto slides is a way of protecting the integrity of the tissue samples they are tasked to closely study. It is vital that tissue samples needed to be examined –or held onto for any amount of time-are safely, and properly, mounted under a cover slip.
