[Campbell Biology P.1029] Which of the following is NOT described in the text as an adaptatio... | Practice Question

Which of the following is NOT described in the text as an adaptation or strategy used by terrestrial animals to conserve water or survive dehydration?

  • A: Waxy layers of insect exoskeletons.
  • B: Nocturnal activity, especially for desert-dwellers.
  • C: Decreasing metabolic rate significantly during activity to reduce water loss.
  • D: Production of metabolic water through cellular respiration.

Explanation

The text describes various adaptations such as waxy exoskeletons A , nocturnal activity B , and producing metabolic water D . However, it does not mention 'decreasing metabolic rate significantly during activity to reduce water loss.' While camels tolerate a 7°C rise in body temperature to reduce water loss, this is not a general mechanism of decreasing metabolic rate during activity.
