← Nature & AnimalsWhich outcome occurs when amphibians transition to terrestrial environments?
A)Urea concentration reduces in tissues
B)Active salt uptake by gills decrease
C)Reduced skin permeability to gas
D)Increased secretion of uric acid✓
💡 Explanation
Increased secretion of uric acid happens, because amphibians transition to conserve water using the osmoregulation mechanism, which synthesizes less toxic wastes requiring minimal water for excretion. Therefore, uric acid concentration increases, rather than urea; this adaptation minimizes water loss more effectively.
