The spot rate for the Argentine peso is $0.3600 per peso. Over the year, inflation in Argentina is 10 percent and U. S. inflation is 4 percent. If purchasing power parity holds, at year-end the exchange rate should be approximately dollars per peso.

The exchange rate should be approximately 0.340364 dollars per peso.

Explanation:

Spot rate = 1 Argentina Peso = $0.3600

Inflation in Argentina = 10 %

U.S. inflation = 4 %

Hence Expected rate =

1Peso (1.10) = $0.3600(1.04)  

Hence

1 Peso = $0.3600(1.04) / 1.10

1 Peso = 0.340364

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.'
