_ are animals that do not adjust their internal osmolarity and are isotonic with their environment.
Correct answer: A. Osmoconformers
- A. Osmoconformers
- B. Osmoregulators
- C. Thermoregulators
- D. Thermoconformers
Explanation
The correct answer is Osmoconformers. These animals maintain an internal osmotic environment that is isotonic to their surroundings, meaning there is no active adjustment of internal osmolarity. This is a passive adaptation strategy. In contrast, Osmoregulators actively regulate their internal osmolarity, keeping it constant despite changes in the external environment. Thermoregulators and Thermoconformers relate to temperature control rather than osmolarity, thus they are not pertinent to the question.

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.
