Question

In light microscopy, which of the following is used as fixatives prior to the staining technique


O Osmic acid

O Heat

O Glutaraldehyde

O None of the above​

Answer 1

heat

because heat very hot thing

Answer 2

Fixatives used to the staining technique in light microscopy

Explanation:

• Chemicals which are used in fixation process are known as fixatives. Fixation process is the process in which tissues and cells are attached to the surface of a microscopic slide.
• Staining is a technique which usually used to kill the cells in microscopy which is required to enhance contrast in microscopic image.
• The chemical fixatives which are commonly used in staining technique for microscopy includes osmic acid and mainly glutaraldehyde.  
• But heat is most commonly used chemical fixatives for light microscopy.

Therefore, Option Heat is correct.
