Why should microscope light be dimmed when viewing living nearly transparent cells?
Human A&P Lab manual (cat version), N. Marieb, Pg. 34
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'

What would be the best microscope for viewing living single-celled organisms in a sample of pond water?
The best microscope for viewing living single-celled organisms in pond water would be a compound light microscope with a high magnification power and a phase contrast or differential interference contrast (DIC) imaging capability. These features allow for clear and detailed observation of the organisms without causing harm to them.
Which type of microscope allows the viewing of living cells?
A compound light microscope is commonly used to view living cells as it utilizes light to illuminate the specimen without damaging it. This type of microscope allows for observation of cells in their natural state, providing valuable insight into their behavior and functions.
Why should he light be dimmed when looking at living nearly transparent cells?
Dimming the light when looking at living nearly transparent cells helps to reduce glare and improve contrast, making it easier to see the cells clearly. Excessive light can wash out details and make it difficult to distinguish fine structures within the cells. Dimming the light allows for better visibility and can enhance the quality of observations when studying transparent cells.
What type of microscope can only be used to view nonliving specimen?
A scanning electron microscope (SEM) can be used to view nonliving specimens such as metals, ceramics, or other inorganic materials. It is not suitable for viewing living specimens due to the vacuum conditions and electron beam used in the imaging process.
What type of microscope do you use to view living organisms?
A compound light microscope is commonly used to view living organisms. This type of microscope uses light to illuminate the sample and allows for observation of live specimens in real time. Additionally, phase contrast microscopy or differential interference contrast microscopy can be used to enhance details in transparent or unstained samples.

What does the phase microscope do?
A phase microscope is used to enhance the contrast of transparent or semi-transparent specimens by exploiting variations in refractive index. It allows for visualization of details that may be difficult to see with a standard brightfield microscope, making it useful for observing living cells and tissues.

A compound light microscope is commonly used to view living organisms. This type of microscope uses light to illuminate the sample and allows for observation of live specimens in real time. Additionally, phase contrast microscopy or differential interference contrast microscopy can be used to enhance details in transparent or unstained samples.
What microscopes can be used to view living samples I. compound microscope II. dissecting microscope III. scanning electron microscope IV. transmission electron microscope?
I and II. Compound and dissecting microscopes can be used to view living samples due to their lower magnification and non-destructive imaging techniques. III and IV. Scanning and transmission electron microscopes are not ideal for viewing living samples as they typically require a vacuum environment and can damage the specimens.
What type of microscope is used to see unstained living microbes and urine specimens for evidence of kidney stones?
A phase-contrast microscope is typically used to view unstained living microbes, as it enhances contrast and allows for visualization of transparent specimens. A polarizing microscope is used to examine urine specimens for evidence of kidney stones, as it can help identify the unique crystalline composition of the stones.
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.
If a scientist wants to look at a small living cell should the scientist use a compound light microscope or an electron microscope?
For viewing a small living cell, an electron microscope would be more suitable as it provides higher resolution necessary to see detailed structures within the cell such as organelles. Compound light microscopes may not have enough magnification power to observe these structures in depth without damaging the cell.
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 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.
