TEMPERATURES: If the temperature of an endothermic homeotherm falls below the ____________, its metabolic rate increases.

Mallard ducks do not produce metabolic heat at temperatures greater than 30℃

B. splendens hemoglobin is bound by more oxygen than T. trichopterus hemoglobin is at P02=50mmHg.  

The value of UCT-LCT (Upper Critical Temperature minus Lower Critical Temperature) will INCREASE.

HEMOGLOBIN: Suppose that an adult’s hemoglobin genes had a mutation that rendered their hemoglobin protein unable to bind to carbon dioxide.  The mutation did not affect the binding of oxygen to hemoglobin, or any other functions or actions of hemoglobin.  Which of the following would NOT occur?

INSECTS: Two insects have the same maximum metabolic rates.  Both are ectotherms, but one is a stenotherm and the other is a eurytherm. Which of the following will always be greater in the stenotherm than in the eurytherm?
