Step 1
Step 2
Does the answer you gave in part i. coincide with the highest air temperature for the day? Explain.
Answer
No, the highest internal temperature for the lizards does not coincide with the highest air temperature. The peak air temperature occurs at a different time, which emphasizes the lizards' ability to absorb heat from their environment effectively, despite the air temperature fluctuations.
Step 3
Is a lizard likely to detect skin temperature by the nervous system or the hormonal system? Explain.
Answer
A lizard is likely to detect skin temperature by the nervous system. This is because there are receptors present in the skin that can sense temperature changes and provide immediate feedback to the nervous system for quick responses, rather than through hormonal regulation.
