Correct answer: A. Heterotherm
- A. Heterotherm
- B. Poikilotherm
- C. Ectotherm
- D. Endotherm
Explanation
A heterotherm is an organism that can regulate its body temperature, but not to a constant level. Instead, it may exhibit fluctuations in body temperature based on environmental conditions. This is in contrast to homeotherms, which maintain a relatively constant internal temperature. Heterothermy allows organisms to conserve energy by adjusting their metabolic rate in response to temperature variations.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
