The tail, if one is speaking of the frogs body only.
A frog's metamorphosis is from a tadpole to a froglet, and a butterfly is from a caterpillar to, well, a butterfly.
The life cycle of the frog begins as a fertilized egg, which then turns into a tadpole. The tadpole grows legs and eventually loses its tail, becoming an adult frog. This process is called metamorphosis, which is any process of transformation, such as that of the immature frog (tadpole) to the adult frog.
The tail of a froglet is absorbed into the body as it undergoes metamorphosis into a frog. The cells in the tail break down and are reabsorbed, allowing the frog to fully transition into its adult form without the tail falling off.

The weight is zero because metamorphosis is a concept of the transformation of a tadpole into a frog. It is an abstract thought, not a physical, tangible object.
A young frog is a tadpole and has a tale and no legs while the adult frog has legs, but no tail.
Metamorphosis.
Metamorphosis is the change of form such as that occurs when a tadpole changes into a frog.
They go through metamorphosis and change into a frog.
Aquatic larva, terrestrial juvenile and adult. Tadpole, froglet (small frog with small tail) and adult frog.
