Question

What is the role of hormones in metamorphosis?​

Answer 1

Answer:

A hormone is any member of a class of signaling molecules, produced by glands in multicellular organisms, that are transported by the circulatory system to target distant organs to regulate physiology and behavior.

In frogs and insects, hormones play an important role in metamorphosis. The hormone thyroxine is helpful in metamorphosis of frog i.e conversion of tadpole to frog.

Thyroxine Hormones secreted by thyroid gland help in growth of frogs. The production of throxine hormones requires the presense of iodine in water. If Ponds do not have sufficient iodine, thyroxine hormone doesn't form and tadpoles are unable to metamorphize into frogs.
