Heat fixing a smear kills the bacteria with minimal distortion, allows for better staining, and firmly affixes the bacteria to the slide. Chemical fixing is used to preserve fine cellular structures and might stop internal processes in place, protect the cell from damage, or strengthen the cell's structure.
you can fix a smear by either heat fixing or chemical fixing.heat fixing preserves the morphological characteristic of the cell while chemical fixing preserves the subcellular characteristics of a cell though it can destroy the enzymatic n protenious contents of such cell.
Take a glass slide and smear [or lay down a thin section of] at least a portion of your/the sample upon the slide. Drying will proceed immediately so to stop this we must apply a fixative agent; thereby af[fix]ing a 'smear'.
The two methods for fixing a smear are: heat fixation and alcohol fixation.
The smear is fixed by passing the glass slide over the flame.
So that during washing with water or treating with alcohol the sample did not flush away.

This paper will aid in keeping the stain over the bacterial smear.
Smear are made for preparing slides for staining which are used in microscopy. The main purpose of smear is to seprate cluster of microbial cells so that we can see them seprately which is helpfull in studying there morphology, and arrangement in colony
adv..... heat fixing inactivates enzymes that would normally disrupt cell morphology and structure during staining and observation. dis....... if not done well much of the specimen can be destroyed in heat fixing.
To avoid denaturing and destroying the smear.
the purpose of boiling of smear in malachite green is to forces a stain to penetrate the endospore wall, it is necessary to heat the slide and the stain to prod the wall to allow the stain to enter.

It is used to fix because to make the cell inactive or immoblie, but the main purpose is to fix the smear so that when we put stain and then flush it out with water ( or some time with alcohol) the smear should not wash out with dye.
methanol for fixing the smear and acetone free to avoid cell membrane lysis

Slight heating helps in fixing the cells on to the surface of the glass slide
A pap smear can't detect pregnancy. A pregnancy test is required for that purpose.

Unless your cervix was removed at the time of your hysterectomy then YES as the purpose of the smear is to find cancerous cervical cells before cancer sets in.

by application of heat and a mordant, the cell can be stained. the purpose of heating is to soften the waxy material of the cell wall and allow the stain enter the cell. rock on University of Luzon!
