Question

Please answer the 3 questions, please provide brief explanation. Urgent, thanks.

31. Why does metabolic rate in endotherms change in a much more linear fashion than ectotherms?

A. evolution in endotherms favors enantiostasis, while evolution in endotherms does not
B. endotherms are better at homeophasic adaptation of membranes, while ectotherms are better at homeoviscous adaptation of membranes
C. endotherms use counter current exchange for thermoregulation, while ectotherms use bidirectional exchange for thermoregulation
D. metabolic rate in ectotherms is physiologically regulated, while that in endotherms is based largely on ambient temperature
E. metabolic rate in endotherms is physiologically regulated, while that in ectotherms is based largely on ambient temperature
