Consider the differences in heart structure between frogs and humans. How might these differences influence the physical activity levels and endurance of each organism?(1 point) Responses The human heart's four chambers and double circulation probably support higher physical activity levels and greater endurance compared to the frog's three-chambered heart and incomplete double circulation. The human heart's four chambers and double circulation probably support higher physical activity levels and greater endurance compared to the frog's three-chambered heart and incomplete double circulation. The frog's heart structure allows for higher physical activity levels and greater endurance than the human heart. The frog's heart structure allows for higher physical activity levels and greater endurance than the human heart. Both heart structures support the same levels of physical activity and endurance. Both heart structures support the same levels of physical activity and endurance. The frog's heart structure supports higher endurance but lower physical activity levels compared to the human heart.

Answer 1

The human heart's four chambers and double circulation probably support higher physical activity levels and greater endurance compared to the frog's three-chambered heart and incomplete double circulation. This is because the human heart efficiently separates oxygenated and deoxygenated blood, allowing for more effective oxygen delivery to the muscles during physical activity. In contrast, the frog's heart has a mixing of blood, which can limit the efficiency of oxygen transport, potentially affecting its endurance and overall physical activity levels.
