BIOL 1010 Lecture Notes - Lecture 6: Decomposer, Autotroph, Mixotroph
Document Summary
Scientists assume : physical world exists, natural causes explain natural phenomena, evidence gathered provides the information to form explanations of the natural world. Science must be: based on evidence, verified (from experiments, falsifiable. Scientific classification: scientists classify in order to . Systems of classification: compare and contrast. Splitting separate for differences: ambiguity refine classification system, dichotomy either/or. 2 mutually exclusive categories no ambiguity. Can be schematic (flow chart) or numeric (arranged like a table of contents) Biological classification: biosphere (large) biochemicals (small) Astronomy and earth science are big, chemistry and physics are smaller. Biodiversity: classical taxonomy naming of organisms, evolutionary divergence. Taxonomy: used to be what things looked like. Relied more on morphology (the study of form and function: now based on things like . Nucleation (if they have a membrane-bound nucleus or not) Plants autotrophic, animals and fungi heterotrophic, protists can be both (mixotrophic) Dna of humans and chimps are so similar, but they"re still not classified together.
