differentiate between physical and biological aspect
Answers
I am somewhat puzzled by your question… not sure what you mean, but will try my best.
If you make a distinction between “physical” and “biological” , than I suppose we need to think about “living” and “non-living” aggregates of matter.
Living system are capable of temporary and localized reversion of entropy, which is a tendency of organized systems to fall into disarray. In absence of external organizing influence atoms, molecules, and things made of them tend to distribute themselves in a way that creates the lowest possible content of free energy (and incidentally also provides the least amount of information about the organization of the system).
Being alive means being able to maintain an organization of an organism, at the level of cells, tissues, organs, and the whole body. capable of performing chemical reactions necessary to support life processes. This requires a constant struggle against Entropy - a constant maintenance, repair, rejuvenation, recycling, and procuring energy. In addition, life processes involve oxidation (even if oxygen is not used), and thus are inherently destructive.
Non-living systems may be capable of reversing entropy - if they are under an influence of some organizing factor. For example, gravity will cause things that have mass to coalesce or sediment - a dusty room left alone for a time will have a layer of dust neatly covering all non-vertical surfaces. Water subjected to removal of heat will become organized in ice crystals; and so on. However, non-living things do not have capability of repairing themselves, or rejuvenating.
Life is quite incredible… and absolutely gorgeous - especially if one looks at it with an informed eye.
