Answer 1

Insufficient production of thyroxine in the tadpoles lead to their incomplete development.

Explanation:

• Tadpole, also known as pollwog is a larval stage in the life cycle of Amphibians especially in frogs and toads.
• In Tadpole stage, the young one doesn't show any resemblance with the adult.
• It is the second stage of the life cycle.
• Tadpoles have big head with long tails and gills for breathing under water.
• The Pituitary glands and the thyroid glands play a main role in the metamorphosis of frog.
• The thyroid gland secretes the hormone callled thyroxine which helps in the change of tadpole into frog.
• The low level of thyroxine or the absence of thyroxine leads to the stunt growth  of the organism.
