Assume that Australia has a comparative advantage in producing surfboards and New Zealand imports surfboards from Australia. We can conclude that: a. Australia also has an absolute advantage in producing surfboards relative to New Zealand.
b. Australia has a lower opportunity cost of producing surfboards relative to New Zealand.
c. New Zealand has an absolute disadvantage in producing surfboards relative to Australia.
d. Labor costs are higher for surfboard producers in New Zealand than in Australia.

answer; ///the correct answer is (organizational effectiveness);

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.'
