Biological Science I -BSC 2010 Spring 2019Unit IDr. Charrel-DennisUNIT 1THEMES IN THE STUDY OF LIFE [Chapter 1]1.New properties emerge at each level in the biological hierarchya.Life can be studied at different levels from molecules to the entire living planetb.The study of life can be divided into different levels of biological organization2.Emergent Propertiesa.Emergent properties result from the arrangement and interaction of parts within asystemb.Emergent properties characterize non biological entities as welli.A functioning bicycle emerges only when all of the necessary parts connect inthe correct way

A growingorganism increases in size in all of its parts, rather than simply accumulating matter.e.Adaptation: The ability to change over a period of time in response to theenvironment. This ability is fundamental to the process of evolution and isdetermined by the organism's heredity as well as the composition of metabolizedsubstances, and external factors present.f.Response to stimuli: A response can take many forms, from the contraction of aunicellular organism to external chemicals, to complex reactions involving all thesenses of multicellular organisms. A response is often expressed by motion, forexample, the leaves of a plant turning toward the sun (phototropism) and by
