A cells internal structure in fine details
The book says "a tem such as the one of sperm cells shown in figure 4 can reveal a cells internal structure in fine detail"
The arrow would likely point to the cylinder lens, which is the objective lens of the microscope. This lens is responsible for magnifying the specimen being observed.
The likelihood of locating an electron at the nucleus is very low, as the electron probability distribution in an atom shows that the electron is most likely to be found in regions farther away from the nucleus.
The transition of an electron between energy levels in an atom shows that the position of the electron is quantized because only specific energy levels are allowed for the electron to occupy. This means that the electron can only exist at certain distances from the nucleus, corresponding to discrete energy levels, and cannot be found in between these levels.
Mechanical advantage is calculated by dividing the output force by the input force. The correct formula is: mechanical advantage = output force / input force.
To calculate mechanical advantage, divide the output force by the input force. The formula is MA = Output Force / Input Force. This gives you an indication of how much a machine amplifies or reduces the input force.
It is black and white.
a TEM (transmission Electron Microscope) shoots electrons through the specimen and shows internal features of the cella SEM (scanning electron microscope) Electrons bounce off of the surface of the specimen, and show a 3d image of the surface on the specimen.a STEM (scanning tunneling electron microscope) uses a needle like probe shoots electrons from the inside out, shows 3D surface image CAN be used on living specimens
Transmission Electron Aberration-Corrected Microscope (TEAM) is the only one capable of resolving individual atoms. Scanning Electron Microscopes can resolve a good amount of macromolecules.
A microscope that shows black and white images is called a monocular microscope. It typically uses a single eyepiece and objective lens to magnify and view samples in grayscale.
electron microscopes...According to my course in OK Virtual Highschool.."Hi-tech electron microscopes are used to study very small objects such as viruses. They can also be used to view the smallest of molecules that make up cells such as DNA in the nucleus. Unlike a compound microscope, an electron microscope can produce a three-dimensional image"

it increased your knowledge you every detail of the cell .it shows you like the inside and every other little detail
A stereo microscope shows two slides side by side at the same time and is used for comparison. A compound microscope only shows one slide.
Electron microscopes are they only type of microscope capable of seeing objects that small. They can be used to look at structures that would normally be too small to see. The following link shows a picture of carbon nanotubes from an electron microscope. These tubes are only a few nanometers wide (approximately 1/50,000th of the width of a human hair).

The second image shows the letter E under the microscope.
In what directions do images move under a microscope?
A scanning tunneling microscope can show detailed surface structures but the organism must be prepared by being plated with a very thin layer of metal. Most organisms can't survive this process. To see a three dimensional image of a living organism you should select a stereo microscope.
