1. The toco toucan possesses the largest beak relative to body size of all birds. The large surface area of their beaks may be an important mechanism for radiating heat (and thereby cooling the bird) as outdoor temperature increases. Shown in the graph are data for beak heat loss as a percent of total body heat loss, at various temperatures in degrees Celsius. 70 60 50 40 20 10 5 10 15 20 25 30 35 TEMPERATURE (°C) a) Would it be appropriate to use the correlation, r, to help describe the strength and direction of this relationship? Explain. b) Which of the following might be a reasonable value for r? i) r = -0.9 ii) r = 0 iii) r = 0.15 iv) r = 0.9 c) What can we conclude about the role of the toco toucan's beak in cooling the bird as outdoor temperatures rise?
