Answer:
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.
