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 would be used to study a specimen smaller than 0.2 micrometers?
The maximum magnification of a light microscope is 2000x. Anything requiring more than 2000x magnification requires an electron microscope.
What are applications of uncertainty principle?
Uncertainty Principle can be used to give a drawback to Bohr's Model of an atom. In that atomic model Bohr said that electrons exist in certain well defined energy levels, to give a contradiction to this statement uncertainty principle may be used.
What organism requires a second organism of the opposite sex in order to reproduce?
The penis requires a vagina in order to reproduce.
What are the differences between a light microscope a compound microscope a stereoscopic light microscope a transmission electron microscope and a scanning electron microscope?
A light microscope uses a series of lenses to focus light allowing small objects to appear larger. A compound microscope works as a light microscope except it uses more than two lenses to increase magnification. A stereoscopic light microscope can be simple (one lens) or compound (more than one lens) and uses two eyepieces.A transmission electron microscope requires the object be in a vacuum and stained (usually with a heavy metal). The microscope fires electrons at the target and measures the diffraction allowing for a computer to generate an image.A scanning electron microscope uses an electron beam to scan the target. It then generates an image by analyzing the variety of signals produced such as secondary electrons released, electromagnetic radiation, and electron deflection.Also an electron microscope can observe a centriole, a tiny structure found in animal cells. Also to break down what a compound light microscope does is that it uses light and a curved piece of glass to make tiny structures appear larger. We can also see many other objects throw a microscope by taking a piece of cut Glass taking for example a piece of string and adding a drop of water then adding a small plastic thing and putting it under a COMPOUND LIGHT MICROSCOPE!!!!!!
Which type of microscope requires a nonmetal sample to be prepared for viewing by coating it with a thin layer of a conductive material?
transmission electron microscope

Give one advantage of a scanning electron microscope over a transmission electron microscope?
The SEM has become more popular than the TEM as it can produce images of high resolution, greater clarity and three dimensional quality and requires less sample preparation.
Why might a microscopist who specializes in the use of microscopes to examine specimens use a light microscope instead of an electron microscope?
An electron microscope requires that the subject be dead to function. In order to receive a picture, the specimen must be coated in chemicals and put into a vacuum, a process which will kill any living specimen. A light microscope, although not as detailed, will allow the scientist to observe living specimens.

Compare and contrast a compound light microscope and an electron microscope?
Light microscope: 1. Uses a beam of light that is focused using glass lenses. 2. Magnification is moderate -- not as much as electron microscope 3. Produces a color image since it uses light 4. Can look directly at the specimen with our eyes Electron microscope 1. Uses a beam of electrons that is focused using magnets. 2. Magnification can be extremely high and show details that are not possible with the light microscope 3. Produces a grey-scale image because color requires visible light 4. Image must be seen on a monitor or in a photograph because we don't see electrons.
What organism requires a second organism of the opposite sex in order to reproduce?
The penis requires a vagina in order to reproduce.
What objective on the microscope requires the most light?
scanning

Can the electron microscope be used to study a live specimen and why?
Not really. An electron microscope requires that the specimen be placed in a vacuum for viewing. It would most certainly kill any living creature placed inside it. No, the specimen being viewed is incapible of life after being placed into the slit.
How are scanning electron vs transmission electron microscopes different?
Transmission electron microscopeMagnification: A series of electrostatic and electromagnetic lenses act on an electron beam to produce up to 50 million times magnificationDepth of field: Very small.Uses: Microbiology, pathology, crystallographyAdvantages: Very high resolution.Disadvantages: Requires extensive specimen preparation, including staining and sectioning with an ultramicrotome. Cannot observe the surface of objects.Very specialized equipment that requires a partial vacuum.Scanning electron microscopeMagnification: Electrostatic and electromagnetic lenses, as with a TEM. Magnification ranges from 25x to 250,000x.Depth of field: Large compared to that of a transmission electron microscope.Uses: Biology, microbiology, geology, nanotechnology, crystallographyAdvantages: Can view objects' three-dimensional surface. Also, an SEM can provide information about the specimen's elemental composition.Disadvantages: As with TEM, requires specialized equipment and a partial vacuum. Cannot be used on living specimens.
