Contrary to this the gamma radioactivity is associated with transmutation of the nucleus. It is the consequence of emission by the nucleus, of an electromagnetic radiation such as visible light or X-rays, however, are considered more energetic. (What is radioactivity?)
The energy generated by the process of radioactivity has significant military and industrial utilities. But the rays emitted out of… read more

Chemical Reactions Occur When Atoms Term Paper …
[. . . .]
This reaction pair is important because the phosphate group is strongly electronegative and bonds formed with the phosphate group have the potential to be high energy bonds. Dephosphorylation is the reverse of phosphorylation, removing one of the phosphate groups.
An isomerization reaction occurs when the atoms of a molecule are rearranged, but there is no addition or removal of atoms.… read more

Beginnings of Life on Early Earth Term Paper …
Life on Early Earth
Questions related to the origins of life on Earth have always been a cause for scientific investigation and suppositions. If we refer to the naturalistic approach, than the evolutionary process is a justified explanation of changes and transformations that have occurred. This is a theory that we can successfully apply to the appearance of life on… read more

Conclusion
Hydrogen and helium constitute the Major share of the elements in the stars. (and the universe). There is a continuous fusion reaction in the stars and their life depends on the amount of fuel left. The presence of higher elements and metals are a direct result of fusion of these basic elements. Spectroscopy has been one… read more
