They are in some way dependent on physiological and physical conditions.

This, I think, is the physiological condition of the young person, John.

This is not like the case of hunger and other physiological stimuli which are conditioned from within.

Modern physiology sets forth as its chief ends: Firstly, the ascertainment of the facts and conditions of cell-life in general.

One deviates thus from the conditions of practical physiology.

And physiologically the form of the vibrations depends upon the condition of the entire vocal apparatus.

The waves can be measured on an electroencaphalograph, and vary with the physiological and psychological condition of the individual.

It has also been established that their physiological efficiency is, under certain conditions, quite equal to that of starch.

It is an abnormal condition of the nervous system giving rise to certain physiological and psychical manifestations.

The screening distance provided by these counterions and water is the Debye length and, in the case of microtubules, its value is typically 0.6-1.0 nm under physiological conditions.
Quantum Computation in Brain Microtubules? Decoherence and Biological Feasibility
He observed that, independently on the past history of the solution, when this is driven back to physiological conditions, a protein (characterized by a given amino acid sequence) folds always to the same equilibrium conformation.
Simple models of protein folding and of non--conventional drug design
Under physiological conditions, these molecules are dissolved in salt solutions with Debye lengths of less than 1 nm.
Screening of hydrodynamic interactions for polyelectrolytes in salt solution
However other proteins (e.g. structural proteins) are almost insoluble under physiological conditions and prefer to form aggregates .
Heteropolymers in a Solvent at an Interface
Under physiological conditions, the double layer potential has an interaction range with a typical length scale of a nanometer, much shorter than the molecule lengths of interest to us; the van der Waals attraction, too, is weak on long scales .
