The biochemistry and biophysics are the notes required for life; they conspire, collectively, to generate the real unit of life, the organism. The intermediate level, the chords and tempos, has to do with how the biochemistry and biophysics are organized, arranged, played out in space and time to produce a creature who grows and divides and is.
