The resolving power of the earliest electron microscopes was at least ten times higher than that of the light microscopes, mainly because the wavelength of electrons is much shorter than the wavelength of light.
The electron microscope uses a beam of accelerated electrons to magnify the object whereas the light microscope uses visible light for this purpose. Unlike the light microscope, the electron microscope uses electromagnets as lenses.
The magnification of the electron microscope is much higher as compared to the light microscope and it produces high-resolution images. However, the Specimen preparation of an electron microscope takes several days while the Specimen preparation of the light microscope takes only a few minutes.

Answer:
They are all called bacterium. Which is the scientific word for bacteria. This is just what all bacteria is called. But there are 5 types of bacteria.
An endangered species is a type of species in which this type of organism has decreasing numbers and are dangerously close to going extinct. Invasive species are species in which an organism invades an environment where it is not native to, and take over the ecosystem. Local species are species in which the organism is native to that environment and plays a key role in that ecosystem. A keystone species is a species in which the organism is a key part of that ecosystem to thrive; without it, the ecosystem would collapse
Answer:
A 0.9% solution of NaCl (saline) is isotonic to animal cells. When exposing animal tissues to solutions, it is common to use an isotonic solution such as Ringer's buffered saline so as to prevent osmotic effects and consequent damage to cells.
