What is a feature of the scanning electron microscope and is not a feature of the light microscope?
It uses electromagnets.
What feature of an electron microscope allows it to achieve resolution at much higher magnifications compared to a compound microscope?
Light microscopes depend on light being reflected by the particles of the substance being studied. However, sometimes the particles are too small to noticeably reflect the light. Electron microscopes function by sending a beam of electrons through a subject; electrons are so tiny that anything can reflect them.
Which feature of a substrate can be accommodated by an enzyme's active site?
The shape, size, and electron configuration of the substrate.
What feature is common to all microscopes and how is this feature related in the word microscope?
All microscopes have lenses. Some types of lenses are eyepiece lenses, objective lenses, and condenser lenses.
Feature of the electron cloud model of an atom?
The electric cloud is the probability of where you can find an electron.
What is a feature of the scanning electron microscope and is not a feature of the light microscope?
It uses electromagnets.
Which feature is featured in the transmission electron microscope and not featured on the light microscope?
it uses electromagnets
What is a feature transmission electron microscope has but not light microscopes?
It can produce images of objects within a cell.
Features of scanner?
There is one main feature of a scanner, which is scanning documents. Scanning documents allows a paper document to be viewed as a computer document.
What is the limiting feature of the light microscope?
the study of earth
What is Scanning and indexing?
Scanning: "to look at all parts of (something) carefully in order to detect some feature(s)" Indexing: "the action or process of compiling an index"

What is an electron feature characterized by specific energy?
Orbital
Advantages and disadvantages of SEM and TEM?
In SEM (Scanning Electron Microscopy) you look at either backscattered or secondary electrones whereas in TEM (Transmission Electron Microscopy) you look how much of your electron beam makes it through the sample onto your phosphor screen or film camera. Usually SEM is used for surface analysis and TEM for analyzing sections.
What can you see under a electron microscope?
An electron microscope can only operate inside a vacuum chamber. A good vacuum, needed so that electrons do not collide with air molecules or dirt before reaching the sample and the detector coming back, would be 1e-7 Torr or below. Your sample (the object of interest) has to be small enough to be mounted on a pedestal, which is inserted into chamber where the electron beam will be. The pedestal has to have multiple degrees of freedom so the e-beam can interrogate at various angle and position. The last requirement would be that your sample does not charge up too easily, which will distort the image. Charging can be lessened with a flash of gold. Hence, if your sample meets the requirements listed, you should be able to see its image on a monitor just as clearly as you see an object of a much larger scale, with an optical microscope. Any items that are detrimental to a vacuum formation (moist, spongy materials, for example) should probably be avoided. From an electron microscope, I have seen something as big as the compound eyes of a fly or a feature as small as 1 nm.
