2. Consider a lizard and a bird, each of 20g body mass and each with optimal body temperature of 40°C. Discuss in detail the thermoregulatory strategies (physiologic and behavioural) they employ to survive the SoCal winter (minimum night temp 2°C, maximum day temp 10°C) and summer (minimum night temp 25°C, peak day temp 50°C). Remember that these ambient temperatures are reported for shade! For each species, draw a graph how the body temperature and metabolic rate change over the course of 24 hours in each season.

What if one of Dr O’s six-footer Komodo dragons got loose and went on the lam on CSUSB campus? How would its thermoregulation differ from that of the 20g lizard? (assume same optimal temperature)

a) Consider a person of 70 Kg. 0.20% of the body mass is potassium and it is a vital nutrient. Natural potassium (mostly 39K and 41K) also contains 0.012% 40K with a half- life time of 1.3 billion years. 40K emits a β- of average energy of 58.5 keV in 89.3% of its decays and a 1.461 MeV γ-ray in 10.7% of the decays. How many of these high-energy γ-rays is generated in the person per second? b) If you...

suppose a bird has a mass of 30 grams. What is the minimum mass of glucose that it must consume to fly from the ground up to a branch 10.0m in height? Assume the glucose is oxidized in the body by O2 to the usual products. You need delta G for this reaction.

Question 2 The Body Mass Index (BMI) is a value calculated based on the weight and the height of an individual. In a small European city, a survey was conducted one year ago to review the BMI of the citizens. In the sample with 200 citizens, the mean BMI was 23.3 kg/m2 and standard deviation was 1.5 kg/m2 . It is reasonable to assume the BMI distribution is a normal distribution. (a) Find the point estimate of the population mean...
