Document Summary
Chapter 5: the nature of life on earth. Six key properties shared by most or all living organisms on earth: order, reproduction, growth and development, energy utilization, energy utilization, repose to the environment, evolutionary adaptation. Order the idea that life tends to be non-random, is seen in the compartmentalization of the human body. And, if multicellular, groups of specialized cells. Cells of different purposes are spread throughout your body non-randomly, performing tasks in an ordered manner. Order alone fails to categorize life, as order can be found in books, crystals, clocks, roads, and more. Order is a necessary condition, though not a sufficient condition, for life as order alone does not make a living thing. All life reproduces or are the product of reproduction. Reproduction:celldivision (almostexactcopy), sex (semi-random combination of genetic codes) Insufficient for life: a mule is the offspring of a horse and a donkey. Mules are sterile and cannot reproduce (yet are a product of reproduction. )
