the bar-tailed godwit is a type of shorebird that makes an annual migration from alaska to new zealand and back. the birds make each 11,500-kilometer (7,145-mile) trip by flying over the pacific ocean in about nine days, depending on weather, wind speed, and direction of travel. one bird was observed to make the entire journey uninterrupted, a feat that is comparable to a human running a nonstop seven-day marathon at 70 kilometers per hour (43.5 miles per hour). would you expect the flight (breast) muscles of bar-tailed godwits to use mainly aerobic respiration or fermentation? explain your answer.

After frida stops exercising, she continues to breathe heavily. what is most likely occurring in her body? heavy breathing during exercise has produced an oxygen surplus in her muscles. this oxygen is being transported to her lungs. this is a result of aerobic respiration. heavy breathing during exercise has produced a carbon dioxide surplus in her muscles. lactate is being transported to her liver. this is a result of aerobic respiration. strenuous exercise has caused her body to be in carbon dioxide debt, and she is breathing hard while lactate is transported to the liver. this is a result of anaerobic respiration. strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. this is a result of anaerobic respiration.
