Key Concepts and Ethical Practices in Biology: Understanding Life Requirements and Lab Techniques

DESCRIPTION

This review covers essential biology concepts, including the requirements for life such as cellular composition, metabolism, response to stimuli, reproduction, energy utilization, waste production, and growth. It underscores the importance of the metric system for scientific communication and highlights the ethical responsibilities of scientists, including the necessity of accuracy and the treatment of human subjects in experiments. Essential lab techniques and the use of sterile methods for studying microorganisms are also discussed, emphasizing safety and ethical considerations in biological research.

Presentation Transcript

  1. Ch. 1 Test Review Biology

  2. Requirements for Life • Know the properties/requirements for life: • Made of cells • Metabolism (sum of all chemical reactions) • Respond to stimuli -*This includes homeostasis where you maintain stable living conditions. • Reproduce *Includes heredity, passing traits on. • Use energy • Produce waste • Grow & Develop

  3. If a puppy grows into an adult dog this is an example of… • A Homeostasis • B Growth & development • C Metabolism • D Made of cells

  4. Metric system • Needed for scientists to speak a common language. • Based on units of 10 • Know your prefixes and units • p. 14

  5. Example… • 1 kilometer = _________m • 1 kilogram = _________ gm 1000 1000

  6. Terms • Chunk the terms to figure out their meaning. • Ex. Biology is… • The study of • Life

  7. Know what these are… • Hypothesis • Observation Use your ___ _______ • How do you test a hypothesis? 5 Senses Perform an experiment!

  8. Lab Safety • Most important rule… Follow the teacher’s directions & remain calm.

  9. Ethics in Science Ethical behavior is needed in science because… • All scientists rely on the work of other scientists. Scientists must report correct information. • People depend on disease breakthroughs to manage their health. Scientists may use people in their tests/trials. • People used in experiments might be exploited or exposed to known dangers if the scientists do not behave ethically.

  10. Lab Techniques p. 15 • We use microscopes to study microscopic organisms “little critters”. • Because these organisms include bacteria it is much more important to use sterile techniques. • Sterile techniques, are methods that keep unwanted organisms out of a lab to reduce risk of contamination.
