Alcohol is a poison (for yeast as well as for people) and so the yeast is not able to grow when the alcohol content gets too high. This is why wine is never more than about 12% alcohol.
Ideally the strong nuclear force would say how the protons and neutrons are bonded together, but there is a conceptual chasm in this area. It is unclear how the residual nuclear force (at nucleus level) emerges from the strong force (at quark level), except as a general concept that the gluons leak out.
Protons and neutrons are held together in the nucleus by the nuclear force, also known as the residual strong atomic force, also known as residual binding energy. Strong atoâ¦mic force (binding energy) holds quarks together to form protons and neutrons. It is the strongest force in the universe, followed by a factor of about 100 by the electromagnetic force, and then by many orders of magnitude by the weak atomic force, and then by many many orders of magnitude by gravity.
