Answer:
transmission EM (TEM) and the scanning EM (SEM)
Explanation:
Electron microscopy (EM) is a technique for obtaining high resolution images of biological and non-biological samples. It is used in biomedical research to examine the detailed structure of tissues, cells, organs and gross cell bodies.
There are two main type of electron microscope
- the transmission EM (TEM)
- the scanning EM (SEM)
- Transmission electron microscopes are used to see thin specimens so that electrons can produce a projection image. TEM can be adapted in many ways to conventional (compound) light microscopes.
- TEM is used for the internalization of cells , the formation of protein molecules, viruses, and organization of molecules in the cytoskeletal filaments. And arrangement of protein molecules in cell membranes.

Explanation:
<h3><u>Answer</u>;</h3>
No, a precipitate does not form
<h3><u>Explanation</u>;</h3>
- Precipitation involves mixing or combining solutions that contain soluble ionic compounds to form an insoluble ionic compound by a reaction.
- Sodium acetate and ammonium sulfate are both soluble ionic compounds, which implies that they exist as ions in aqueous solution.
- <em><u>When they combine they form NH4CH3COOH and sodium sulfate, Na2SO4, which are both soluble salts, as all salts of ammonium and sodium are soluble.</u></em>
- <em><u>Both ammonium acetate and sodium sulfate are soluble because there are no anions that can form an insoluble solid with NH4+ and Na+ cations. </u></em>
