Transcript

  • 1. CHAPTER ONE BIOLOGY AND YOU
  • 2. THEMES OF BIOLOGY
    • HOW DO WE KNOW AN ORGANISM IS ALIVE?
  • 3. THEMES OF BIOLOGY
    • CELL STRUCTURE AND FUNCTION
      • SMALLEST UNIT OF LIFE
      • SINGLE AND MULTICELLULAR LIFE
  • 4. THEMES OF BIOLOGY
    • REPRODUCTION
      • ALL LIVING THINGS REPRODUCE
      • ESSENTIAL TO THE SURVIVAL OF THE SPECIES
  • 5. THEMES OF BIOLOGY
    • METABOLISM
      • ALL THE CHEMICAL RXNS CARRIED OUT BY THE BODY
      • CHEMICAL RXNS=ENERGY=LIFE PROCESSES
  • 6. THEMES OF BIOLOGY
    • HOMEOSTASIS
      • MAINTAINING STABLE INTERNAL CONDITIONS
      • CHILLS, SWEATING, FEVERS
  • 7. THEMES OF BIOLOGY
    • HEREDITY
      • LIVING THINGS PASS ON THEIR TRAITS TO OFFSPRING
      • LIVING THINGS HAVE GENES/DNA
  • 8. THEMES OF BIOLOGY
    • EVOLUTION
      • THE CHANGE IN HERITABLE CHARACTERISTICS OVER TIME
      • POPULTAIONS EVOLVE
  • 9.
    • NATURAL SELECTION
      • NATURE “SELECTS” INDIVIDUALS THAT HAVE TRAITS THAT BEST FIT THE ENVIRONMENTAL CONDITIONS
      • “ SURIVIAL OF THE FITTEST”
  • 10. THEMES OF BIOLOGY
    • INTERDEPENDENCE
      • ORGANISMS IN A COMMUNITY DEPEND ON EACH OTHER AND THE NON-LIVING FACTORS
        • SUN, TEMP., WATER, MINERALS
  • 11. BIOLOGY IN YOUR WORLD
    • HOW HAS SCIENCE IMPROVED OUR LIVES?
  • 12.
    • SAVING THE ENVIRONMENT
      • Rainforests, Extinction, Recycling
    • FOOD SUPPLY
      • Genetic engineering
        • Herbicide resistance, vitamins
  • 13.
    • HUMAN GENOME PROJECT
      • GENOME: Complete genetic material of an organism
      • Read Genes and Find Where Mistakes Have Been Made
  • 14.
    • FIGHTING DISEASE
      • AIDS VACCINE
      • CANCER TREATMENTS
      • EMERGING DISEASES
        • WEST NILE, MAD COW
      • GENE THERAPY
        • REPLACING DEFECTIVE GENES WITH NORMAL ONES
        • CYSTIC FIBROSIS
  • 15. SCIENTIFIC PROCESSES
    • SCIENTIFIC PUZZLES ARE SOLVED BY:
      • MAKING OBSERVATIONS
      • ASKING QUESTIONS
      • COLLECTING DATA
      • Ex. Rocky Mountain Amphibians
  • 16. DSIGNING AND EXPERIMENT
    • HYPOTHESIS
      • AN EXPLANATION THAT CAN BE TESTED
      • PREDICT WHAT WILL HAPPEN
    • PLAN THE EXPERIMENT
  • 17.
    • CONTROL GROUP: RECEIVES NO EXPERIMENTAL TREATMENT (PLACEBO)
    • DEPENDENT VARIABLE: WHAT WE ARE MEASURING
    • INDEPENDENT VARIABLE: WHAT IS MANIPULATED IN THE EXPERIMENT
  • 18.
    • EXPERIMENTS ARE REPEATED TO VALIDATE THE HYPOTHESIS
    • ONCE THE HYPOTHESIS HAS BEEN CONFIRMED NUMEROUS TIMES IT MAY BECOME THEORY
  • 19.
    • THEORIES ARE WELL SUPPORTED BUT NOT ABSOLUTE
