What else can I help you with?
Does a light microscope used to view live or dead samples or its range of magnification?
A light microscope can be used to view both live and dead samples. The range of magnification for a light microscope typically falls between 40x to 1000x, depending on the specific lens and microscope configuration.
Do you use the scanning tunneling microscope for live or dead samples?
The scanning tunneling microscope (STM) is typically used for imaging surfaces of materials at the atomic level, regardless of whether the sample is alive or dead. The STM works by scanning a sharp metal tip over the sample surface and detecting the tunneling current between the tip and the surface, allowing for atomic-scale resolution imaging. It is commonly used in both materials science and nanotechnology research.
Who was the first person to witness a live cell under a microscope?
The first person to witness a live cell under a microscope was Antonie van Leeuwenhoek in the 17th century. Using a simple microscope he designed, he observed single-celled organisms in various forms of life.
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.
How can one observe tardigrades in their natural habitat?
To observe tardigrades in their natural habitat, one can collect samples of moss, lichen, or soil from areas where tardigrades are known to live. These samples can then be placed under a microscope and searched for the tiny, water-dwelling tardigrades. It is important to handle the samples carefully and use proper microscopy techniques to avoid harming the tardigrades or their environment.

What are the advantages of an phase-contrast microscope over a compound light microscope?
Can view live samples and observe motility and responses to stimuli

Why do biologists continue to use the light microscope since the invention of the electron microscope?
Biologists continue to use light microscopes because they are versatile, easy to use, and cost-effective for observing live samples. Light microscopes are better suited for visualizing large-scale structures and dynamic processes in living organisms. Electron microscopes are mainly used for high-resolution imaging of smaller structures at the subcellular level.

One limitation of the scanning electron microscope is that it cannot be used to?
One limitation of the scanning electron microscope is that it cannot be used to observe live samples or biological materials in their natural state. The high vacuum environment and the electron beam can damage or alter the 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 is the difference between live vaccine and dead vaccine?
Vaccines are usually small amount of the disease you are trying to prevent. Introducing small amounts of the virus or bacteria, whether it is live or inactive, stimulate your immune system to strengthen its defenses against that germ.
What major advantage of the transmission electron microscope have over a compound light microscope what is the major disadvantage?
The major advantage of a transmission electron microscope (TEM) over a compound light microscope is its ability to achieve much higher resolution, allowing for visualization of cellular structures at the nanometer scale. This is due to the use of electrons instead of light, which have shorter wavelengths. However, the major disadvantage of TEM is that it requires extensive sample preparation, often resulting in the destruction of the specimen, and it cannot be used to observe live samples.
When is it better to use a light microscope rather than an electron microscope?
When you need to observe a live specimen
