"Without engaging in international trade, Freedonia and Lamponia would have been able to consume at the after-trade consumption bundles" is FALSE.

Option: B

Explanation:

Specialization refers to countries' propensity to focus in certain items they exchange for other commodities, rather than to manufacture all the consumer goods on their own. As the PPF production possibilities frontier displays that production is impractical, Freedonia and Lamponia had to engage in international trade.

Both countries are able to consume the goods they produce.When a country is skilled in manufacturing a good, it can manufacture this good at a lower cost of opportunity than its trading nation. For this comparative advantage, both countries benefit from competing and trading with one another.

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.'
