Presentation Transcript

  1. Do Not Copy: • I will be able to explain feedback mechanisms and their role in maintaining homeostasis. 10-15 minutes Warm up 11/6 & 11/7 Answer What do proteins and nucleic acids have in common? Compare the structures of cells and viruses?

  2. 5 minutes Needs to be turned into the box by end of day today • From Last Class • Active Transport Practice • Exit Ticket • From Today • Feedback Mechanisms Questions (from reading) • Cell Transport Practice Independent Practice • Exit Ticket

  3. Do Not Copy: • With your elbow partners discuss the following. 10 minutes What do you think? Answer When repairing damaged cells like a burn on your finger how does your body know when to stop producing cells? What are some examples of how your body maintains homeostasis?

  4. 10minutes Feedback Reading • Use this time to quietly read the reading on homeostasis and answer the questions for Part 1.

  5. 5 minutes Homeostasis Notes • Write these in your notebook under the title homeostasis notes

  6. Homeostasis • Body’s ability to maintain a balance or an equilibrium • Examples: • Body Temp • Blood Glucose • Calcium Levels

  7. Receptor- receives info • Control Center- controls the response • Effector- carries out response Feedback Loop

  8. 10 minutes • Read Part 2 and Answer the questions Feedback Reading Part 2

  9. Negative Feedback- works to keep conditions constant (temp, glucose, etc.) • Positive Feedback- will go beyond normal range (blood clotting) 5 minutes Feedback Notes

  10. External- Happening outside the body • Internal- Happening inside the body Feedback Notes cont.

  11. You have 5 minutes to summarize the notes from today • Write the main points in your own words 5 minutes Summary

  12. Do Not Copy: • With your elbow partners discuss the following. • Look at the feedback loop on the reading page 10 minutes What do you think? Answer What type of feedback loops do you see in the picture positive or negative? How do you know? What type of feedback loops do you see in the picture (internal or external)? How do you know?

  13. Cell Transport Independent Practice 15 minutes • Complete the cell transport independent practice and turn in by the end of the period • If you have any questions please ask

  14. 10 minutes Exit Ticket 11/6 & 11/7 • 1. Describe a negative feedback loop in your body. • 2. Describe a positive feedback loop in your body? • 3. Which type of feedback loop do you think there are more of in your body. Explain how you came to that conclusion. • Turn it into the box when leaving w/ your name on it
