    Study Notes

    Biology as an Experimental Science

    • Biology involves an inquiry process of asking questions about the characteristics of living organisms
    • Biologists gather information to answer questions and form hypotheses
    • Hypotheses are tested through experiments to validate their accuracy

    The Influence of Biology

    • Biology has a significant impact beyond textbooks and classrooms
    • Biologists have developed various treatments for human diseases through drug discovery
    • Biological technologies have diverse applications, such as:
      • Using microorganisms to produce medical products, like human insulin
      • Genetic engineering of crops to make them resistant to specific insect pests
