Solution
True; Standard metabolic rate is use for ectotherms. False, SMR is dependent upon temperature because ectotherms rely on temperature. False; post absorptive and active animals have not digesting capacity as the endotherms have. True, they have lower resting metabolite rate because of temperature dependency. Thermoregulation occurs in hypothalamus which placed in ventral part of the diencephalon. So sensors for thermoregulation are in the diencephalon part of the brain. Heat loss may associate to vasoconstriction, countercurrent exchanger, sweating, moving out of the wind on a cold day. Evaporation is the method of heat loss but NOT heat gain.
