The model dependence of the concept of "nucleon in nuclei" is emphasized, starting from the example of the ground state of nuclear matter. How to reconcile this model dependence with the necessary model independence of predictions for observables is discussed. As an illustration, the deuteron ...
What does the nucleus do in a cell? What is the purpose of the mitochondria? Explain. Why is the nucleus considered the control center for the cell? What is the role of the nucleus in cell division? How is the form of the nucleus related to its function?
The nucleus is found in every cell of the living organism except in a few such as in prokaryotic cells. It is referred to as the director of the cell. It performs various functions at the molecular level. The membrane that covers the nucleus is called the nuclear membrane....

Nuclear energy is the energy held in the nucleus of an atom. This is released through nuclear reactions like fission and fusion. Nuclear power is a term commonly used to describe electricity made from nuclear energy. However, in science, energy and power are different units of measurement. ...
which is caused by particles being shot out of the nucleus. It was known that a great deal of energy is locked up in the nucleus, but, until just before the outbreak of the Second World War, there was no way of releasing this energy in any large quantity. A revolutionary discovery was...
The Nucleus: In eukaryotic cells, the nucleus holds the DNA. DNA is arranged in long strands, each being called a chromosome. The normal human nucleus has 46 chromosomes. These chromosomes are identical in each cell, thanks to the process of cell division. ...
Apoptosis is characterized by a series highly regulated biochemical events that lead to significant changes in cellular morphology and ultimately cell death (Table 1). In the earlier phases, a cell undergoing apoptosis loses cell contacts and changes shape. Chromatin condenses in the nucleus and move...
A nucleon is a collective term for protons and neutrons inside an atomic nucleus, while the nucleus is the core of an atom, containing nucleons and thus most of the atom's mass.
