The heating allows the stain to intensify, therefore allowing the chromosomes to be seen more clearly

The rate of heat loss from the hot cup change during the experiment answer?
The rate of heat loss from the hot cup decreased during the experiment.
What will happen if too much heat is applied while heat fixing a slide?
When too much heat is applied during the heat fixing of a slide with a bacterial cell on it, the cell would explode. The membrane of the cell would rupture.
What is a laboratory burner used for?
It is used for production of heat during experiment or during chemical reaction by labouratory users.
Purpose of fixing the bacterial film?
The purpose of heat fixing the bacteria to the slide is so during the gram staining procedure the bacteria doesn't wash off. If you didn't heat fix the bacteria to the slide, it would not stay on the slide.
During the performance of the simple staining procedure you failed to heat fix your EColi smear preparation Upon microscopic examination how would you expect this slide to differ from correct slide?
The bacterial smear will wash away during the staining procedure. This is avoided by heat fixation, during which the bacterial proteins are coagulated and fixed to the glass surface.
What would you expect from a gram stain done on a slide that was heated too hot during the heat-fixed smear?
A Gram stain refers to a staining technique for the identification of bacteria. A Gram stain done on a slide that was heated too hot during the heat-fixed smear will destroy the cell wall of the bacteria.
Why during the experiment the content in the crucible is not weighed while ist is still hot?
heat rises. less mass i think
Why steam heating is done in acid fast staining and not heat fixing?
Actually, both methods are used during the staining procedure (steam & heat fix). Initially, the organism is heat fixed to the slide to prevent the organism from being washed off during subsequent steps. Later in the procedure, the slide with the heat fixed organism is steamed to make the cell wall a little more penetrable - allowing the stain to enter the cell wall.
What would happen if no heat fixing were done?
If no heat fixing was done to a slide with a specimen on it, it would be rinsed off with the gram staining procedure. Heat fixing the specimen does kill specimen but it also locks it in place.
How do you change sedimentary rock into a metamorphic rock?
You squash it and heat it up.
How do a metamorphic rock change into sedimentary rock?
You squash it and heat it up.
What is the conclusion on specific heat capacity of liquid experiment?
The theory of the heat transfer experiment is the transfer of thermal energy between molecules, due to a temperature gradient. The conclusion of the experiment is that thermal conductivity is much higher in metals and does not change within thickness.
