Has an absolute advantage in the production of alfalfa, and has an absolute advantage in the production of barley. Musashi's opportunity cost of producing 1 bushel of barley is
bushels of alfalfa, whereas Rina's opportunity cost of producing 1 bushel of barley is
bushels of alfalfa. Because Musashi has a opportunity cost of producing barley than Rina, has a comparative advantage in the production of barley, and has a comparative advantage in the production of alfalfa

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
