  1. Emergent Biological Hierarchy
    • The whole > sum of all parts
    • Ex: Memories = emergent properties of nerve networks
  2. Reductionism
    • Sum of parts > whole
    • reducing complex system into smaller easier parts
    • ex: Studying DNA to understand inheritance
  3. Systems biology
    • 1) components working together
    • 2) any level of organization is a system
    • 3) tries to model behavior from interaction of parts
    • 4) predicts how a change in one affects other part or the whole system
    • 5) answers large scale questions
  4. Levels of Organization
    • Biosphere > Ecosystem > Community
    • >Population > Organisms> Organs and systems >Tissues > Cells > ORganelles  >Molecules

  5. Structure & Function....
    correlated at all levels
  6. Negative feedback
    • accumulation of end product(output) slows the process
    • ex: sugar broken down to make ATP, excess ATP inhibits more breaking down
  7. Positive feedback
    • product(output) speeds up production
    • ex: Blood clotting: damaged blood vessels > platelets
  8. Taxonomy
    • names and clasifies species
    • uses shared characteristics to make order
  9. Domains of lyfe
    • Bacteria (prokaryotic)
    • Archaea (prokaryotic)
    • Eukarya (eukaryotic)
  10. Eukarya kingdoms
    • 1) Plantae (photosynthesis)
    • 2) Fungi (absorption)
    • 3) Animalia
    • *distinguished by mode of nutrition
  11. Natural Selection
    • Descent with modification
    • Common ancestors
  12. Types of Data
    • Qualitative
    • QUantative
