6. "Place the slide on the stage, and locate the cells at the lowest power. You will probably want to dim the light with the iris diaphragm to provide more contrast for viewing the lightly stained cells. Furthermore, a wet mount will dry out quickly in bright light because a bright light source is hot." The answer I believe is 'to provide more contrast'

Which type of microscope allows the viewing of living cells?
scanning tunneling electron microscope, or STM
A tiny unicellular living thing from a local pond takes up a quarter of the fielf of view of a microscope on low power what is the actual size of the living thing you are viewing?
im a house cat and i took a dump in that pond
Which invention allowed us to discover cells?
Robert Hooke is credited for discovering and naming the cells found in both living and dead organisms. Using the bark of a cork tree, he was the first to see cells under a microscope.
What type of microscope do you use to view living organisms?
light microscope
What type of microscope can only be used to view nonliving specimen?
The light microscope and the electron microscope refers to the type of microscope that is used to view the non- living specimen. The non-living specimen is usually placed in a slide.

What medical term describes tissue being removed from a living body and viewed through a microscope?
A biopsy is the medical term that describes the procedure of removing tissue from a living body for examination under a microscope. This procedure helps in diagnosing diseases and determining the characteristics of the tissue sample.
What is the Medical term for to remove the tumor?
flargenerman biopsy - live tissue sample. microtomy or histotomy - the making of thin tissue samples for viewing under a microscope.
What type of microscope do you use to view living organisms?
light microscope
What type of microscope can be used to view non living specimens?
The light microscope and the electron microscope refers to the type of microscope that is used to view the non- living specimen. The non-living specimen is usually placed in a slide.
What is the main disadvantage of the electron microscope over a compound microscope?
You can only view non-living things under the electron microscope, while with the compound you can view living organisms
What is a phase microscope?
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.
What type of microscope can only be used to view nonliving specimen?
The light microscope and the electron microscope refers to the type of microscope that is used to view the non- living specimen. The non-living specimen is usually placed in a slide.
What microscope provides the greatest magnification of preserved living specimens?
Transmission electron microscope
What microscope is used to observe a small living organism in a lab?
A contrast or optical microscope.
