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.

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.
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
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'.
How many fossil kits with 12 samples each have the same number of fossils as 30 fossil kits with 8 samples each?
20
Microscope is an indespensable tool why?
A microscope (literally ~ 'see small') is a device to aid our natural eyesight. A low power microscope (<40 times) is very useful in inspection of samples, and in dissecting small structures. Such as parts of a flower. Stereo microscopes are good in this region. From here you go up to medium power 'scopes, up to a few hundred times. You'll now be looking at the grains of sandstone and similar small items. A binocular microscope will be useful, but you'll no longer have stereo presentation. Much more than a few thousand becomes difficult for a light microscope, for your subjects themselves approach the wavelength of light in size. Beyond this, electron microscopes rule, and they may not actually look at the specimen directly. They fire a beam of electrons at the specimen, and display the results on a video screen. But you can have much more fun here, for if the electrons are sufficiently energetic, they can cause secondary emission from the sample, and analysing these emissions can identify the elements in the sample. You'll now be looking at part of an individual grain of a sandstone. And with an EM microscope it is simple to copy the picture from the video screen.
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.
What is a tool that magnifies samples?
A lens, magnifying glass, microscope.
What microscope provide 3D images of samples?
My black Dick
Are samples for compound light microscope prepared on glass slides?
Yes
Which microscope is often used to view metal surfaces?
Metal samples among others can be viewed by a light microscope. The light microscope, also known as an optical microscope, can view microorganisms.
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 does the base do on a microscope?
The microscope base provides a steady mount for the microscope and samples, minimizing giggle and wobble. It also provides a foundation for the lighting, traversing, and focusing mechanisms.
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
What is a ken a vision microscope?
Ken vision microscope is a brand of microscope which OS used to look at cells, blood sAmples or small particles microscopes are.used generally by scientists.
What does a scanning tunneling microscope allow scientists to see?
The scanning tunneling microscope scans samples using a very fine metallic tip.
What technology can be used to capture images of blood samples and other fluids?
a telemedicine microscope
When each data value in one sample is matched with a corresponding data value in another sample the samples are known as?
Matched Samples
