Assume, for Canada, that the domestic price of tomatoes without international trade is higher than the world price of tomatoes. This suggests that, in the production of tomatoes, a. Canada has a comparative advantage over other countries and Canada will export tomatoes. b. other countries have a comparative advantage over Canada and Canada will import tomatoes. c. other countries have a comparative advantage over Canada and Canada will export tomatoes. d. Canada has a comparative advantage over other countries and Canada will import tomatoes.

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.'

a. primarily outdoors, responding to emergencies and protecting people.
