Question

Metamorphosis in frog can be accelerated by

• A. $K$
• B. $Ca$
• C. $I_2$
• D. $P$

Answer 1

The correct option is C $I_2$

Metamorphosis is a process in which the physical form of an animal develops and changes after birth or hatching through the process of cell differentiation and cell growth.


Thyroxine plays a significant role in frog’s metamorphosis.

Iodine is an essential component required for the synthesis of thyroxine.

Increased concentration of iodine will therefore, increase the rate of metamorphosis and a deficiency of iodine can retard the growth of a larva to become an adult frog.
