Thermoregulation In Humans
Questions: Part 1. Consider the following experiment (reference below). It has long been thought that antioxidants decrease risk for developing cancer. This was tested by giving either the antioxidant Vitamin E or placebo at random to 35,000 men, and measuring how many were diagnosed with prostate cancer 5 years later. There was no statistically significant difference in prostate cancer rate between the groups at the end of the study. 1. What was their hypothesis? (Be specific) 2. What was their treatment group? 3. What was their control group? 4. What was the dependent variable? 5. Can they broadly conclude that ALL antioxidants do not prevent ALL cancers? Why or why not? **Careful, this is tricky. Reference: Lippman SM et al. Effect of selenium and vitamin E on risk of prostate cancer and other cancers. JAMA. December 9, 2008. Part 2 Design an experiment that you could do to test homeostasis of body temperature. Do not make a big deal about this. Think about the things that might make the human body heat up. 6. Explain your hypothesis 7. Explain your treatment 8. Describe your control 9. What is the dependent variable? 10. How could your experiment be strengthened?
