Answer:
Endothermic
Explanation:
Heat is retained while exothermic means heat is released
That table salt has a high melting point and mercury's melting point is low.
Answer:
The principal physical properties of milk include its density, redox properties, colligative properties, surface activity buffering capacity, rheological behaviour, conductivity, thermal properties and color.
Explanation:
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.
The statement in option B is not correct. B is the correct answer. This is because nuclear fission usually occur in large unstable isotopes, which are bombarded with high speed particles like neutrons, which make them to split into smaller particles. The statement in option A, C and D are true about nuclear fission.
