Cells are communicating, Agobot. Not molecules. The molecules are used
to communicate.
A water molecule in the human body is not different in any way from a water molecule in the ocean. It's still 2 Hydrogen atoms and 1 Oxygen atom. The bond holding the molecule together is identical. Their behavior is identical. There is no difference.
An iron atom in your body is no different from an iron atom in a bridge in the same way. There is nothing intrinsically different between then two.
This is how the sensation of touch is transferred between atoms, through electrical signaling. This is offtopic but we are much closer to being an electromagnetic phenomenon, than a body of solid matter, despite the illusion created by your brain.
First you say molecules are communicating, and now you say atoms are communicating, while your source says that cells and organs are communicating.
And then you start your "electromagnetic phenomenon" and illusion gibberish.
Once again Agobot, you're the only one speaking nonsense in this thread. You have absolutely no diea what you're talking about.
