Animals that are not isotonic with their environment and have developed mechanisms to regulate their internal solute and water concentrations are:
Correct answer: B. Osmoregulators
- A. Osmoconformers
- B. Osmoregulators
- C. Thermoregulators
- D. Both (A) and (B)
Explanation
Osmoregulators are organisms that actively regulate and maintain a constant internal osmolarity, independent of the external environment. They adjust their internal solute concentration to cope with varying external conditions, ensuring stable cellular function.

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.
