← Nature & AnimalsWhich result develops when pit vipers use heat-sensing pits during venom injection?
A)Increased vasoconstriction in prey's peripheral tissues✓
B)Enhanced perception of prey body temperature
C)Heightened metabolism of toxin enzymes injected
D)Weakened immune system avoiding defensive reaction
💡 Explanation
Localized vasoconstriction intensifies blood clotting by concentrating venom via hemostasis, because heat pits target crucial sites. The venom acts more efficiently; therefore, vasoconstriction dominates, rather than immune response or enzymatic activation.
