Explain your answer.?ANSWER:??Amphibians have the simplest lung – it is not convoluted and thus has a low surface area. In addition, air is pushed into their lungs which limits flow. Mammals have far more convoluted lungs to increase surface area and have the anatomy to draw air into the lung. However, there is still a delay as air comes in and then goes out.

Their hypoxic blood stimulates the kidneys to secrete erythropoietin which leads to increased levels of red blood cells. At altitude, these red blood cells are necessary to carry sufficient oxygen levels. However, these additional red blood cells will benefit the athlete by allowing them to carry more oxygen to their muscles when they compete.?DIFFICULTY:??Bloom's: AnalyzeREFERENCES:??38.8 Respiratory AdaptationsLEARNING?OBJECTIVES:??UDOL.STES.16.38.12 - Examine the adaptations that help organisms respire in extreme environments. ................
