Answer:

Those who grow in iodine-deficient water cannot grow into frogs because they (ta) need enough iodine to grow. Therefore, I concluded that t cannot grow in iodine-deficient water.

The growth and development of the animals like tadpole is controlled by the hormone called thyroxine produced by the thyroid gland. Thus, if the water in which tadpole is living is deficient in iodine, it retards its growth and metamorphosis. Therefore, it cannot develop into an adult frog.

Answer:

in short

the tadpoles has a gland in their brain which is called pituitary gland that is also called master gland so tadpoles grows through thyroxine hormone which is released by thyrod gland. the salt contain salt so therefore salt gives us iodine which is necessity of the tadpoles to grow because to keep the tadpoles growing to frog the thyroid gland is more important and it was balanced by salt so therefore tadpoles need salty or iodine water to grow if sufficient amount of thyroxine is not produced if there is no salt in water

the then the growth hormone {GH} Will does not occur in tadpoles and growth stip
