What are three uses for microscopes?
Three uses for microscopes are forensics, reasearch, and analysis.
What is the difference between the reason that and the reason why and just the reason?
The first is to describe why something HAD TO happen. The second is to describe why something DID happen. Just "the reason" is what it is, and it can be used in three different ways. You used two of them in your question
What is the difference between a normal guitar and a junior guitar?
The difference between a normal guitar and a junior guitar is primarily its size. A Junior guitar is shorter and about three quarters the size of a normal guitar.
What is the difference between a dissecting microscope and a regular microscope?
Microscopes are used both in classrooms and in making important evaluations in medical laboratories and other microtechnologies. The different types of microscopes are designed for these different uses, and therefore will vary based on their resolution, magnification, depth of field, field of view, illumination method, degree of automation, and type of image they produce. There are essentially three categories of microscopes: electron, confocal, and compound. Electron microscopes are extremely sophisticated types of magnification devices. These are used in archaeology, medicine, and geology to look at surfaces and layers of objecs such as organs and rocks. Instead of using light, these devices point a stream of electrons at the specimen and attached computers analyze how the electrons are scattered by the material. The specimen must be suspended within a vacuum chamber. With transmission electron microscopes, a scientist gets a view of 2-D slices of the object at different depths. Of course, with such powerful instruments, both the degree of magnification and the resolution, or sharpness of the image, are very high. Scanning electron microscopes are slightly different in that they scan a gold-plated specimen to give a 3-D view of the surface of an object. This view is in black and white, yet gives an amazing picture of, for example, the minute hills and valleys of a dinosaur bone. A confocal microscope is a step down from the previous types. It uses a laser beam to illuminate a specimen whose image is then digitally enhanced for viewing on a computer monitor. The specimen is often dyed a bright color so the laser gives a more contrasting image. It is mounted on a glass slide just like in high school biology. Confocal microscopes are controlled automatically, and motorized mirrors help with auto-focus. Finally, there are the simplest types of microscopes found in classrooms across the world: compound microscopes. These are entirely operated by hand and use the ordinary ambient light from the sun or a light bulb to illuminate the specimen. Whatever you want to look at is mounted between two glass slides and clipped beneath the main lens. You use a dial to focus the image. These tools use a simple series of magnifying lenses and mirrors to bring the image up to an eyepiece, much like a telescope. Compound microscopes are mostly used in biology. They give a 2-D slice of an object, yet can attain a high enough magnification to see parts of eukaryotic cells, a hair strand, or pond scum. Unfortunately, they do not have excellent resolution, so the image may be blurry. On the other hand, stereoscopic microscopes, as the name implies, provide a 3-D picture of bisected items, like muscle tissue or an organ. In this case, magnification is poor, so you can't make out separate cells, but resolution is much improved.
What is a difference between seasonal and cyclical variations?
seasons change very three months but cycles change rate vary from one to five years
What are three uses for microscopes?
Three uses for microscopes are forensics, reasearch, and analysis.
Why is 1.75 different than 1.34?
They are different numbers, with two out of the three digits different in them. There is a difference of 0.41 between them.
How are light microscopes and electron microscopes alike?
They r alike because they both are able to have the three zooms to different levels and they both focus on small mircoscopic organisms.

they have different enviernments
Why are binocular microscopes necessary for microscopy?
Because the word "stereo" indicates more than one. Like the difference between mono and stereo sound.
