By "retroaction" every bond changes in the higher whole [i.e. when the whole increases (in size), the nature of the chemical bond between that whole's constituents, its atoms, changes. The changed whole retroacts on its constituents, especially on the bonds between them]. Only in the case of crystalline periodicity and amorphous homogeneity the retroaction becomes uniform and the change with increasing size soon approaches zero [Growth, i.e. increase in size, in both periodic and homogeneous bodies, does not change the qualitative content of such a body, whereas in true molecules (dead or alive) addition (or subtraction) always brings with it a qualitative change]. A satisfactory answer clarifying the nature of the bonding condition is not to be expected. Especially the easily measurable energy states are bad qualitative indicators if one cannot determine relevant difference values from sophisticatedly contrived exchange reactions under coapplication of approximated boundary-type representatives. With truly living substance one virtually cannot, in this sense, experiment at all.
