Question

Approximately how many watts does a 50,000 gram human at rest (about 110 lbs) generate from metabolic heat? If kangaroo rats were moved from the desert to northern tundra, where temperatures are much colder, and then allowed to evolve for many generations, which of the following adaptations might you expect for heat retention? A larger body size. A smaller body size and lower movement rate. A lighter skin color that reflects more sunlight. The development of sweat glands. Where would you expect a freshwater fish to get most of its water from? Secretion Absorption Metabolism of food Evaporation

Explanation / Answer

Answer 37- We know that Heat production at rest is equal to 1 W/ Kg

For a weight of 50 Kg the Heat Production is equal to –

= 1* 50 W

= 50 W

Answer 38- Option B

A smaller body size and lower movement rate will help in conservation of energy hence the correct answer.

Answer 39: Option b

Fresh water fish gets water by the way of absorption
