What is the working mechanism of electron microscope?
Transmission: A beam of electrons pass a sample and is absorbed in electron-dense structures, which look black in an image. Scanning: samples are coated with metal and scanned with a beam of electrons.
What type of microscope provides the greatest resolution?
Depth of field in a microscope refers to the distance between the nearest and the furthest objects that produce a distinct image of a specimen. It is usually very short and is measured in microns.
What is a working distance of a microscope?
the distance between the specimen and the objective lens
How does the working distance affect the size of objects that can be viewed under a stereo microscope?
As you increase the magnification, you decrease the working distance.
Does the working distance increase or decrease as one moves to higher magnification with the microscope?
decreases

Was the electron microscope invented in Germany?
Yes. German engineers Ernst Ruska and Max Knoll built the first machine in 1931 in Germany. It didn't outperform the best optical microscopes, but it served to demonstrate the ideas. A couple of years later, Ernst Ruska (working for Siemens in one of their German locations) built an electron microscope that surpassed the resolution limits of an optical microscope. Wikipedia has a nice article on the history of the electron microscope, and a link is provided to that post. You'll find it below.

What do microbiologists use while they are working in the lab?
Microbiologists use many job specific tools to complete their investigation. Most importantly , a high end electron microscope with proper mounting wares are a essential.
Can you drive a vehicle without a working transmission?
Of course not. Without a working transmission you are going nowhere.
