Question

what will happen if the water in which tadpoles are growing does not contain sufficient iodine?

Answer 1

Heya friend,


A hormone released by the thyroid gland is a signal for metamorphosis in many amphibians like frogs. This hormone requires the presence of iodine in water for its production. If the water in which tadpoles are growing is deficient in iodine , the tadpoles fail to grow and cannot become adult frogs.



Thanks

Answer 2

Answer:

Tadpoles cannot mature into adults if the water they are growing in does not contain enough iodine.

Explanation:

• The hormone thyroxine, which is made by thyroid glands, regulates metamorphosis in frogs. Iodine must be present in water for the formation of thyroxine, and metamorphosis cannot occur if iodine is absent or present in insufficient amounts.
• Many amphibians, including frogs, have a thyroid hormone that serves as a signal for metamorphosis. Iodine in water is necessary for the formation of this hormone. If the water in which tadpoles are developing lacks iodine, the tadpoles will not develop and will not be able to become adult frogs.
