When exposed to acutely hypoxic conditions, many endotherms lower their body temperature. This response is advantageous because A) there is an associated drop in metabolic rate. B) it causes a decrease in the affinity of haemoglobin for O₂. C) it triggers hyperventilation and increased cardiac output. D) less oxygen is taken from the blood by the myoglobin in muscles.
