The Steroid Hormone That Coordinates Molting in Arthropods Is

Question

The steroid hormone that coordinates molting in arthropods is
A) ecdysone.
B) glucagon.
C) thyroxine.
D) oxytocin.
E) growth hormone.

Accepted Answer

Ecdysone is a steroid hormone that controls the molting process in arthropods. It is secreted by the prothoracic glands and triggers the production of enzymes that break down the old cuticle, allowing the arthropod to shed its old exoskeleton and grow a new one. Glucagon, thyroxine, oxytocin, and growth hormone do not play a role in the molting process in arthropods.
