Document Summary
Acid breaks down material in the bone and nutrients transferred. 90% of organisms in marine environment have yet to be recognized. Cell - defining property of life; all living things are made of cells. Cell biologist vs virologist definition of life. Scientists can"t agree on an absolute definition of life. Erwin schrodinger - defined living matter as that which avoids the decay into equilibrium . Refers to 2nd law of thermodynamics - entropy always increases. Entropy ~ often referred to as chaos/disorder, but is really the spreading out of energy towards a state of uniformity. B/c of this trend toward equilibrium universe is eventually characterized by complete lack of structure. Schrodinger argued living things could postpone this trend ^^ Living things resist entropy by taking in nutrients, expelling waste products the body maintains its structure through metabolism (a sign of life)
