Higher prices of imported resources will: A. shift the aggregate supply curve to the left B. move the economy downward and to the right along the aggregate demand curve C. make the aggregate demand curve steeper D. shift the aggregate demand curve to the left

A. shift the aggregate supply curve to the left

Explanation:

This is because, the higher the prices of imported resources, the higher the quantity supplied while at the same time the quantity purchased would be lower.

yup the answer is

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.'
