A particular species of gecko (a reptile) seeks to maintain a body temperature of between 23°C and 27°C during the day. Below are measurements of a resting gecko's heart rate when the animal's body temperature is 24°C and 26°C. Calculate Q10 for heart rate based on these data. Show your work, and explain if this indicates that heart rate is temperature-sensitive or not. Temp 24 HR 21, Temp 26 HR 23.
a. Q10 = (HR at 26°C / HR at 24°C)^(10 / (26-24))
b. Q10 = (23 / 21)^(10 / 2)
c. Q10 = (1.095)^5
d. Q10 = 1.61

The Q10 value calculated is 1.61, which indicates that the heart rate is temperature-sensitive. This means that the heart rate of the gecko increases by approximately 61% for every 10°C rise in temperature.
