A small mammal has an optimum body temperature of 38.0 °C.
At 0 minutes, the temperature of its surroundings was increased from 20 °C to 35 °C. A body temperature control system was active in Trial 1 and blocked in Trial 2.
| Time in minutes | Body temperature in Trial 1 in °C | Body temperature in Trial 2 in °C |
|---|---|---|
| 0 | 38.0 | 38.0 |
| 5 | 39.1 | 39.1 |
| 30 | 38.0 | 40.8 |
Use the data to explain how the control system carries out homeostasis.
Predict and explain what could happen to the rate of reactions in the mammal's cells if its body temperature continued to increase in Trial 2.
