Unformatted text preview: Lecture notes: Book notes: see summary plus the following: Chapter 1 : The Nature of Science and Characteristics of Life Nanobes: smallest living organisms? Biology: the study of life Scientific method: observations, hypothesis, predictions, experiments (observe, hypothesize, predict, test) Theory: proved hypothesis Fact: direct and repeatable observation Cell: smallest and most basic unit of life, DNA: hereditary (genetic) material that transfers information from parents to offspring Evolution: change in genetic material or DNA over time Species: organisms that can interbreed to produce fertile offspring Populations: groups of organisms within a species that live and interact with one another Virus: contain DNA, but not made up of cells, lack structures within cells necessary to perform nearly all activities that living organisms do, RNA: not living molecule, tissue, organ, organ systems, individual, community (population of species that live and interact with one another), ecosystem (communities with physical environments they inhabit), biomes (large regions of the world defined on land by the plants that grow there, ie artic tundra), biosphere (all worlds living organisms and places they live) producers, consumers, decomposers Chapter 2 : Organizing the Diversity of Life, see notes shared derived features (ancestors pass on) vs convergent features (happen to evolve) Linnaean haierarchy: o Genus, (ie homo sapien) o family, order, class, phylum, kingdom o Domains: bacteria, archaea (bacteria like organisms known for living in harsh environments), eukarya (rest of living organisms) o Bacteria (bacteria), archaea (archaea), (protista, plantae, fungi, animilia: eukarya) DNA studies: suggest that we are closely related to fungi and plants (chimpanzee is most common) Horizontal gene transfer: genes being passed vertically (normal, from one generation to the next) and moving across from one lineage to another Chapter 3 : Major Groups of Living Organisms (see summary) eukaryotes: contain organelles, compartments that perform specialized functions...
