What are The important uses of the microscope?
A microscope's general use is high powered magnification; it can also be used for forensic purposes(fingerprints, DNA samples, etc.); or scientific purposes (I.E. disections); or health.
What is an advantage of using an electron microscope?
Answer: Using an EM (electron microscope) you can look INSIDE a cell and take photos. This is different to an ordinary (or Light microscope) where you generally only see the outside of the cells - or at best can only see vague shapes inside the cell. Answer: The scanning electron microscope provides a number of advantages over an optical microscope. Primarily this centers around the fact that the wave lengths used are much smaller than the wavelengths of light. What you can see is, in par,t dependent on the relative size of the object and wavelength of the light you are using. For very small objects, like individual atoms, light just wont work. Secondly the electron microscope can be fitted out with equipment and analytical sensors to identify the atomic composition of materials in the field of view. These Scanning Electron Microscopes (SEM) are extremely useful in identifying trace contaminants. The standard microscope still has advantages. It can detect the polarizing capacity of organic compounds, it is cheap and easy to use, it can be used in the analysis of stained samples in microbiology, it can use transmitted light and reflected light to examine an object. A major advantage is that the surface of the viewed object does not have to be prepared by being covered with a very thin layer of metal to permit viewing.
Inclination joint in microscope?
An inclination joint of a microscope is where the arm of the microscope connects to the base of the microscope. Many microscopes have a pin to hold these to objects together. If the microscope is equipped with the pin you can place one hand on the base and with the other hand you can grab the arm and rotate it back and forth. The inclination joint allows the microscope to tilt back for more comfortable viewing. Please note, there is no way to contain liquid specimens if you tilt your microscope back the liquid will spill to the ground or all over.midfielder_francis@yahoo.com
Why do agricultural inspectors check samples of grain with a microscope before permitting the grains?
Because the grains might have fungus diseases and a few of these diseases change the kernels of growing grain into bags of useless fungal spores. Farmers and gardeners spend millions of dollars on fungicides each year because of these diseases.
We were sent following samples through TNT on 01.04 this sentence is correct or not?
Better to say: We were sent the following samples through TNT on ..................(the date should be clear, 01.04 isn't very clear). After this sentence there would be a list of the 'samples'.
Are samples for compound light microscope prepared on glass slides?
Yes
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
How does a compound microscope use lenses to magnify an object?
the optical microscope is a type of microscope that uses visibal light and a system of lenses to magnify images of small samples
What are the use of compound microscope?
To examine blood samples, stools, small part of plant's bodies,etc
How is tularemia diagnosed?
Samples from the skin lesions can be prepared with special stains, to allow identification of the causative bacteria under the microscope.
How must samples be prepared by observation by an electron microscope?
They must be preserved and dehydrated. Once this is accomplished, put the specimen onto a slide, and then the slide is ready to be viewed under the microscope.

Why do biologists continue to use the light microscope since the invention of the electron microscope?
Because you can examine living samples, the electron microscope can only examine killed samples.
When is a 'real world' situation where a compound microscope would be essential?
To check fecal samples in animals for worms, To check for bugs in breaking water, etc.
How is brightfield used?
Brightfield microscopic illumination is used mainly to examine stained specimens, ie blood samples, cellular details, etc. It can also be used to examine unstained specimens that are not transparent......... Zeiss Guy
What is one advantage of using the dissecting microscope instead of a compound light microscope?
A dissecting microscope has a lower magnification than a compound microscope. A dissecting microscope has a bigger work area so you can use it to magnify and still move around what ever your looking at. A compound microscope would be used to look at cells that you could not see with out intense magnification You would have to use a microscope slide for whatever you wanted to look at. Example: A dissecting microscope would be used to figure out the sex of Fruit flys. While a compound would be used if wanted to see the cells of a the fly's eye
What is a micoscrope?
A microscope is an optical instrument used for viewing very small objects, such as mineral samples or animal or plant cells, typically magnified several hundred times.
