Which of the following is the reason why John’s body is better able to acclimate to temperature than his new baby?
  1. Age
  2. Size
  3. Composition
  4. All of the above
Explanation
Answer - D - Infants have less ability to acclimate to temperature than do adults because of immature organ processing. In older adults, lessened ability is also noted as a result of failing organs. Body size and composition, specifically fat composition, can also be reasons for differences that different people have at being able to acclimate to temperature.
