Answer:

The electron microscope uses electrons to form images for this reason does not allow to observe living cells because they need to work in a high vacuum atmosphere, the samples require preparation through a long fixation process, which means that it is not possible to observe living cells. To observe a cell with this microscope, dead cells must be observed, after being fixed and stained with heavy metal ions.

In these microscopes it is not possible to observe the cells carrying out their normal behaviors (for example, migrating or dividing) under the microscope

Which type of Electromagnetic waves on the spectrum has the highest<br> energy? Why?
Marina CMI [18]

Explanation:

Each section of the electromagnetic (EM) spectrum has characteristic energy levels, wavelengths, and frequencies associated with its photons. Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum.
