Document Summary
Life shares the same fundamental physical building blocks. Life is as an emergent property of a collection of specific nonliving things: ex: mitochondria not alive but part of a living cell, put non-living things together in the right way = life. A system with a source of variation. Cells are the unit of life: composed of chains of chemicals. Science that tries to explain complex patterns in the world around us. Complicated behaviors and patterns can often emerge from simple underlying rules: ex: keep an appropriate distance from neighbor, keep aligned with neighbor, avoid predator, etc. Flock of birds or school of fish. Biological systems: cells - brain - behavior. Behavior of molecules based on the rules of chemistry. Life oxygen, carbon, and hydrogen are the most abundant. Carbon forms the backbone of most key molecules of life. Water (h2o) accounts for most of the oxygen. All life forms on earth are carbon-based (organic) - the backbone of biology.
