When nations impose currency controls on their economics some firms benefit and some are hurts?

True

Explanation:

I can explain this question using a current example of currency manipulation by a foreign government. In Argentina different governments set the exchange rate between the Argentine peso and the US dollar. Sometimes the peso is devaluated by the government which makes Argentinean products and services cheaper to export but makes all imports more expensive. These actions favor economic growth but also increase the inflation rate.

On other occasions the government will appreciate the Argentinean peso against the dollar which makes imports cheaper and exports more expensive. Supposedly this is done to control high inflation rates.

If you wonder why the Argentinean government does that, probably no one really knows. Its been happening since the 1990s and different political parties have governed the nation but this practice of artificially setting the currency value never stopped.

answer is i don't know

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.'
