What is the function of ecdysone in molting: (a) initiates the process in response to stretch receptors, (b) regulates the process of shedding the old exoskeleton (ecdysis), (c) causes hardening of the new exoskeleton, (d) directs the epidermis to secrete a new exoskeleton, (e) controls the type of exoskeleton that is produced

The correct answer is B and D

Explanation:

Ecdysis is the molting of the cuticle in many invertebrates of the clade ecdysozoa since the cuticle of this animals typically forms a largely inelastic exoskeleton. it is shed during growth and a new larger covering is formed. the remnant of the old empty exoskeleton are called exuviae.

After molting an arthropod is described as teneral, a callow it is fresh, pale and soft bodied. within one or two hours the cuticle hardens and darkens following a tanning process analogous to the production of leather.
