  • 1. Welcome to Biology Room A101 Mrs. O’Hara  Please have a seat
  • 2. Branches of Biology
  • 3. The Molecular Level  Study the molecular units of life.
  • 4. The Molecular Level  Study the molecular units of life. – Investigate the workings of DNA.
  • 5. The Molecular Level  Study the molecular units of life. – Investigate the structure of DNA. – Study basic organic molecules (protein, fat, carbohydrate…)
  • 6. The Molecular Level Study the molecular  units of life. – Investigate DNA. – Study basic organic molecules (protein, fat, carbohydrate…) Example: studies the drugs on DNA.
  • 7. The Cellular Level Studies cells. 
  • 8. The Cellular Level Studies cells.  – Studies how cells divide
  • 9. The Cellular Level Studies cells.  – how cells divide – structure and function of a cell
  • 10. The Cellular Level  Studies cells. – Studies how cells divide – Studies the structure and function of a cell Example: what happens to cancer cells exposed to tobacco.
  • 11. The Multicellular Level Studies Multicellular  Organisms. Zoologists set up bat traps

  • 13. The Multicellular Level Studies Multicellular  Organisms. – Animal Anatomy – Plant Physiology. Zoologists set up bat traps
  • 14. The Multicellular Level  Studies Multicellular Organisms. – Animal behavior – Plant and animal structure and function. Example: How do roses reproduce. Zoologists set up bat traps
  • 15. The Population Level Studies groups of  organisms. Zoologists set up bat traps
  • 16. The Population Level Studies groups of  organisms. – How does a population interact with the environment. Zoologists set up bat traps
  • 17. The Population Level Studies groups of  organisms. – How does a population interact with the environment. – What is the effect of humans on nearby life. Zoologists set up bat traps
  • 18. The Population Level Studies groups of  organisms. – How does a population interact – What is the effect of humans on nearby life. Example: How does bees communicate? Zoologists set up bat traps
