  1. Human & the Biological World L100 Dr. Susan Hengeveld Lectures: T&Th 9:30-10:45 A106 Labs: T - 1:25-4:25pm JH 122 (not 122A)

  2. “The Process of Science” • see pg. 10-15 • hypothesis: • theory: • correlation: fig 1.8 • experiment:

  3. Biology: The Study of Life Common Properties of all Living Organisms: • cellular organization • metabolism • homeostasis • growth & reproduction • respond to stimuli

  4. Biology: The Study of Life Common Properties of all Living Organisms: • heredity • capacity to adapt • all organisms posses • populations of organisms

  5. Classification of living things: • hierarchical categories place all living things into a classification groups. • Domains • Kingdoms fig 1.5

  6. Living Organisms interact with each other than the world around them! • Biology is the study of life. • understanding individuals • understanding how individuals interact with others & their physical world fig 1.6

  7. fig 1.7 • Understanding Biodiversity: • Population • Community • Ecosystem

  8. Four Underlying Theories of Biology: • The Cell Theory: Organization of Life -- all living organisms are -- understanding how • The Gene Theory: Molecular Basis of Inheritance -- all organisms share -- genetic code determines

  9. (3) The Theory of Heredity: Unity of Life • Unity: • genes of an organisms are • characteristics are passed • shared characteristics

  10. (4) The Theory of Evolution: Diversity of Life • diversity • populations evolved - • variation in fig 1.8
