  In the first part of the present paper we give an analysis of the ontic
nature of quantum states to be intended as potentialities and of the central
role of spin to be considered as the basic essence of quantum mechanical
reality: using an algebraic quantum like structure we give mathematical proof
on the transition from potentiality to actualization : we recall here what was
recently given by us in arXiv quant-ph/0607196. However, as may be expected, it
is not so easy to introduce examples containing an adequate description of
ontic potentialities through detailed models of systems. The central aim of
this paper is to attempt to reach this objective giving direct cases of systems
in which ontic potentialities act jointly to actualization. Our aim is to
provide evidence for the possible importance of potential states in the sphere
of the biological dynamics giving detailed examples of interest for biological
studies. We outline the possible implications of potentialities at the level of
linear and non linear biological dynamics.
