BIOL 105 Lecture Notes - Systems Biology, Prokaryote, Eukaryote
Document Summary
Evolution accounts for the diversity and unity of life. Scientists form and test hypotheses to study nature. Science benefits from a cooperative approach and diverse viewpoints. Biology is the scientific study of life. We recognize life by what living things do. New properties emerge with successive levels of biological organization. Life can be studied at different levels of complexity. Enormous range can be divided into different levels of biological organization. Reductionism - the approach that reduces complex systems into more simple components. Simpler components are more manageable to study. Emergent properties result from arrangement and interaction of parts as complexity. Functioning machine only emerges when all necessary parts connect in the correct way. Systems biology analyzes interactions among parts of the biological system. Used to study life at all levels. Each level of biological hierarchy correlates structure and function. Analyzing biological structure gives clues to physiology. Analyzing function gives clues to structure and organization.
