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.
The nuclear force holds protons and neutrons together. While less than the force of binding energy, it is still more powerful than the electromagnetic force, so the protons with a charge of +1, though tending to repel each other, still stick to each other.he nuclear force holds protons and neutrons together.
