Is an electron microscope used to magnify a living specimen?
An EM is basically of 2 types. Scanning Electron Microscope and Transmission Electron Microscope. Yes definitely it is used to magnify and resolve specimens but a living specimen cannot be used. Only dead are used. This is due to certain disadvantages that come along with this microscope. If need further details over the microscope uses and types then let me know.yea...i completely agree wif yuh... :)
Why electron microscope cannot be used to study life processes?
because an electron microscope has a vaccum chamber which cannot allow oxygen to pass
Can you detect ribosomes if you're using an up-to-date light microscope to examine animal cells?
No, you cannot.
Which organelles are visible under an electron microscope but not under a light microscope?
all i know is that the ribosomes cant be seen and i dont think mitochondrion can be seen either... help me out people! The electronic microscope provides a 3-D vision on the speciman.
What organisms cannot be viewed by using the compound microscope?
Viruses. They are smaller than the average wavelength of light and as such are not viewable unless an electron microscope is used.
What are the Kinds of microscopes and their uses?
There there are many. Simple microscope, compound microscope, light microscope, scanning electron microscope, TEMicroscope, Dissection microscope, etc and most of them are used to see small cells that cannot be seen by the naked eye.
What microscope is used for observing yeast mitochondria?
Light microscope cannot be used. An electron microscope houl b used

Does an electron microscope need electricity?
Yes, an electron microscope cannot operate without a source of electrical power.
One limitation of the scanning electron microscope is that it cannot be used to?
One limitation of an SEM is that it can't observe living things while still alive. Biological samples must be coated in gold before observation.
Can colors be seen with an electron microscope?
No, they cannot due to the fact that the electron microscope does not use light rays to illuminate the object; therefore, colors cannot be see since they are a reflection of light.
Summarize information about electron microscopes using five or six bullet points?
1. electron microscope could magnify until 200,000 and have high resolution 2. they cannot be used on living organisms because it enters a vacuum so electron don't bounce off a gas molecule 3. it allow you to view molecule 4. electron microscope is a beam that hits a specimen and hitting back to draw the molecule in the fluorescent screen this is called transmission electron microscope 5. there is a scanning electron microscope that scans specimen coated by a thin layer of metal ions that bounce back forming 3-D image
Can you see the atoms of elements with a powerful school microscope?
No, you cannot see individual atoms of elements with a school microscope. Atoms are much smaller than the wavelength of visible light, so they cannot be resolved by optical microscopes. Specialized techniques such as scanning electron microscopy or atomic force microscopy are needed to visualize atoms.
How much magnification is needed to see a nanometer?
You cannot see down to the nanometer scale with light microscopes, you have to use something like a scanning tunneling microscope or an electron emission microscope. And since those don't use light I'm not sure you can really define the magnification.

No, you cannot.
