Question
7. Why might you observe different values for the normal range of a measurement on different days or at different times (even for the same person)? 8. What factors might determine the differences seen in heart rates? These are variables that might influence our data. 9. What steps could we take in our experimental design to control some of these variables? 10. Suggest a possible hypothesis for differences in heart rates and describe briefly how we might test this. Apply your knowledge: 11. The hormone calcitonin is released from the thyroid gland in to increased levels of calcium ions in the blood. If this hormone is part of a negative feedback loop, what effect would calcitonin have on blood calcium levels? 4
