Calculate the Q10 (see introduction) for the change in heart rate between 0°C–10°C; 10°C–20°C and 20°C–30°C of Daphnia magna. Use the mean heart rate from all the Daphnia measured in the class at each temperature for your calculations.
Question 1 (10 marks) 1. Desert animals experience large daily variation in environmental temperature, with high temperatures during the day and low temperatures during the night. What effect do you expect a drop in temperature from 25°C to 0°C would have on the heart rate of an ectotherm (e.g. a lizard) compared with an endotherm […]
