Q: How do humans adapt to very cold temperature ?
  • A. By reducing the production of red blood cells, lowering the binding affinity of hemoglobin and increasing the breathing rate.
  • B. By increasing the production of red blood cells lowering the binding affinity of hemoglobin and increasing the breathing rate
  • C. By hibernating.
  • D. By increasing the production of white blood cells, lowering the binding affinity of hemoglobin, and increasing the breathing rate.
Correct Answer: Option B - Humans have various physiological and behavioral adaptations to cope with cold environment . Some of these adaptations are : • By increasing the production of red blood cells, humans can increase the oxygen-carrying capacity of their blood. • By lowering the binding affinity of hemoglobin, humans can facilitate the release of oxygen from the blood to the tissues. • By increasing the breathing rate, humans can increase the intake of oxygen and the removal of carbon dioxide.
