BIO SCI 150 1st Edition Lecture 1 Introduction to ClassBiology: Understanding how living systems use stored information to reproduce molecules and structures using chemistry to ‘cheat’ the laws of physics.Theory: All living creatures have cellsEmergent Properties: The whole is much greater than the sum of its parts – living systems show a hierarchy of organization in which novel emergent properties can be seen at each level. At each level new properties emerge that were not present in the previous level.Living systems show:Unity: All living systems derive from a common ancestor – evolutionDiversity: Evolution leads to diversity – there are differences in species and individualsTypes of Organisms:Prokaryote: No nucleus (Bacteria and archaea)Eukaryote: Has Nucleus (mitochondria)Virus: Not living “pure information” (the genetics of a virus are similar to the genetics of the creature carrying the virus)Types of Classification:3 Domains: Bacteria, Archaea, EukaryotesBy Characteristic: Prokaryote: No nucleus, bacteria, archaeaProtista: Unicellular or simple multicellularPlantae: PhotosyntheticFungi: Absorptive eatingAnimalia: Eat by ingestionApproaches to Biology:Holism: Must be intact to be realReductionism: Reduce to simple units to understand the whole organism.Scientific Method: provides framework for gathering, organizing, and expanding knowledge. Is a seven step system that consists of; observation, hypothesis, predictions, experiment, controls, conclusion, and can end in theory.Major Theories in Biology:Cell theory: The cell is the basic unit of living systemsThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Gene Theory: Information, DNA, RNA, protein synthesisTheory of Heredity: Information is passed on to the next generationTheory of Evolution: Decent with
