What else can I help you with?
Why are stained or dyed before being looked at with a light microscope?
because the dye goes into the cracks of the cells and makes it easier to see each individual one.
Was stained glass invented before or after the middle ages?
stained glass was first developed?
What should be done before viewing through a compound microscope?
you should make sure the microscope is clean and ready. and that it is set on the right setting. i actually have no clue . suckerrr
Why are cells stained or dyed before being looked at with a light microscope?
Cells are stained or dyed before being viewed under a light microscope to enhance their visibility by adding color to specific parts of the cell, making it easier to identify different structures. Staining can help researchers distinguish between different cell types, visualize cellular structures more clearly, and highlight specific components of interest within the cell.
What is a contrast phase?
A phase-contrast microscope (or phase-difference microscope or phase microscope) allows better viewing of clear specimens that usually need to be stained before you can make out the various parts. Staining is a time consuming process and kills the cells being viewed. With a phase-contrast microscope, living cells can be studied as they go through the cell division cycle.HOW IT WORKSAs light goes through a transparent specimen, there may not be anything interesting to see. However, the light undergoes phase changes as it passes through the different parts of the specimen. Unfortunately, the human eye does not notice phase changes. A phase-contrast microscope converts these unnoticed phase changes into differences in brightness, which the human eye sees very well. The darker and lighter parts of the specimen make it very visible.This also works on reflected light microscopes.

The darker and lighter parts of the specimen make it very visible - and it is still alive!This also works on reflected light microscopes.
Were cells discovered before or after the invention of compound microscope?
it was form in1665 by robert hooke through his self desing microcope
Why should you watch from the slide before you lower the objectives of your microscope?
Movements viewed through the microscope are exaggerated quite a bit. As such, it's best to attempt to line up the object on the slide by looking at the slide directly, rather than through the objective.
Why are bacterial blood cells stained before examination?
transparent
How must samples be prepared for observation by an electron microscope?
Samples for observation by an electron microscope are typically prepared by fixing the specimen in a chemical solution, dehydrating it, and then embedding it in a resin for stability. The sample is then sliced into ultrathin sections using a microtome before being stained to enhance contrast. Finally, the prepared sample is placed inside the electron microscope for imaging.
Why do you have to pull apart a stained tissue with needles before putting it on a cover slip during mounting?
It sounds like what you are really asking is why one hast to separate stained animal or human tissue using needles before putting it on a glass microscope slide. If that is the case, the answer is so that you do not contaminate the delicate tissue by touching it with your hands.
What is the first and foremost thing to know before you can use a microscope?
the first and foremost thing to know before you can use a microscope is how to use it?
