Animals that are unable to adjust their internal salt concentration according to external environments is:
Correct answer: D. Osmoconformers
- A. Anhydrobiosis
- B. Osmoregulators
- C. Thermoregulators
- D. Osmoconformers

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.
