Suppose interest rates rise in the United States, but they don't rise in other nations. What is the impact on the flow of financial capital, the value of the dollar, and U. S. net exports (based on the changing value of the dollar)

Net Inflow / Appreciate / Decrease

Explanation:

When interest rates rise in an Economy relative to the rest of the world ceteris paribus, it has the effect of increasing the value of the Currency of the country in question.

This is because more people will want to invest in the country to take advantage of the higher interest rates. This Net Inflow of Financial Capital will lead to more demand for the American dollar which will as earlier mentioned, cause it to appreciate according to the laws of Demand and Supply.

As a result of the Dollar being stronger, US exports will be more expensive as they are quoted in dollars. Less people will buy it so US exports will decrease leading to a Decrease in Net Exports.

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.'
