By using 2-dimension graphs (in MS WORD) for PRICE and QUANTITY, demonstrate the effect that each of the following will have on the demand for gasoline in a competitive market? State what happens to demand. Explain your reasoning in each case and relate it to a demand determinant. If you are not able to use MS-WORD, just draw on a piece of paper, take a picture, and submit it as a PDF file. If you cannot use MS Word tools, just use your pen and paper and upload images or screenshots.

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.'
