For some organisms, events in this process can include elongation of the imaginal discs and chromosome puffing, which are dependent on ecdysone.
For some organisms, events in this process can include elongation of the imaginal discs and chromosome puffing, which are dependent on ecdysone. In some animals, this phenomenon is marked by a spike in urea cycle enzymes, corresponding to a transition from ammonotelism to ureotelism. The "complete" form of this action is called (*) holometabolism and confers offspring the advantage of not having to compete with imagines, or adults, as they occupy different ecological niches. This process is regulated by prolactin and thyroxine in animals such as Xenopus. Animals undergoing this process are called pupa, and insects may form a chrysalis or cocoon during it. For 10 points, name this process observed in flounders, frogs, and butterflies.
