Biology Insights for Informed Decisions

Enhance your understanding of biology to make informed decisions about health, environment, biotechnology, and unanswered questions in science. Discover the impact of genetics on health, biotechnology pros and cons, and the importance of biodiversity. Explore how biology raises questions, including memory storage, virus mutations, and extraterrestrial life possibilities. Gain insights on pseudoscience, biology's role in advances, and the ethical considerations of biotechnology applications.

Presentation Transcript

  1. KEY CONCEPTUnderstanding biology can help you make informed decisions.

  2. Objectives for section 1-5 (page 28) • Describe how yours and the environment’s health depend on biology • Give pros and cons of biotechnology. • Explain why science creates more questions than it answers.

  3. Your health and the health of the environment depend on your knowledge of biology. • Knowledge of biology helps you understand your health. • food allergies • potential effects of obesity

  4. Knowledge of biology helps you understand your health. • cancer • effects of alcohol, tobacco, and other drugs Smoker’s damaged lung, black by tar Non-smoker lung

  5. Knowledge of biology can help you understand environmental issues. • interactions in ecosystems • pollution • biodiversity

  6. Biotechnology offers great promise but also raises many issues. • Biotechnology is the use and application of living things and biological processes.

  7. Exxon Mobil Cool Animation - Blue-Green Algae + Red Prototype Car Commercial

  8. Biotechnology is the use and application of living things and biological processes. • DNA testing in medicine and forensics • transgenic (genetically modified) crops • transgenic bacteria

  9. Questions are raised about the use of biotechnology. • safety of genetically modified crops (GMOs) • spread of undesirable genes • decrease in biodiversity • ethical considerations

  10. Biology presents many unanswered questions. • Over the past 50 years, biological knowledge has greatly increased.

  11. There are still many questions to answer in biology. • How are memories stored in the brain???

  12. Clip from Disney’s Inside Out How are memories stored in the brain?

  13. capsid nucleic acid lipid envelope surface proteins • There are still many questions to answer in biology. • How do viruses mutate? • Does life exist on planets other than Earth?

  14. Science vs. Pseudoscience! • Science NOTTUS (Natural, Observable, Testable, Tentative, Uncertain, Social.) • Pseudoscience  false science (astrology) • Protoscience  Emerging or near science • Nonscience  does not meet NOTTUS, usually based on belief or philosophy

  15. Quick Quiz Time  • Each question will be worth 2 points • You may NOT talk and/or communicate with a classmate • Scores will be collected and recorded at the end of the chapter

  16. 18. Knowledge of biology can promote advances by helping all people make • Strong opinions • Informed decisions • Profitable products • Individual values

  17. 19. The use and application of living things and biological processes is known as • Medical research • Human biology • Epidemiology (study of disease) • biotechnology

  18. 20. Which is a true statement about biology’s unanswered questions? • Unlikely to change anything • Many remain unasked • Few existed in the past • Rarely depend on technology

  19. Trade your paper with a non-lab partner
