LEARNING ACTIVITY SHEET GRADE 10 SCIENCE Part C: POSITIVITY AND NEGATIVITY Read each situation below and complete the negative and positive feedback loops using the phrases in the box. Write the letter of your answers in the box provided. SITUATION 1: After doing a strenuous activity, you feel that your temperature increases. | A. The skin and brain sense change. STIMULUS B. There is a decrease in body temperature. RECEPTOR. C. The skin produces NEGATIVE FEEDBACK sweat. SIGNAL D. There is a command from the brain. E. There is an increase in body temperature. RESPONSE Response leads to AS RICH SITUATION 2: When labor begins, the head of the baby is pushed downward, and this results in contraction of the cervix. A. The receptor cells send a chemical STIMULUS signal to the brain. Oun CLLENCE B. There is a release of 3 / 4 охytocin. RECEPTOR C. There is more contraction of the cervix. POSITIVE FEEDBACK SIGNAL D. The birth of the baby is successful. RESPONSE. Response leads to E. There is increase pressure on the cervix. Think About It! 1. Based on the first situation, how does the feedback mechanism regulate homeostasis in body temperature? 2. In the second situation, does positive feedback result in homeostasis? Why or Why not? Specific Weeks: 1-3 (LAS 1) Target Competency: Explain the role of hormones involved in the female and male reproductive systems (S10LT-Ilb-34)
