PLEASE ANSWER ASAP I AM BEING TIMED!!!
gayaneshka [121]

Answer:

Apart from poisoning the fish, this toxic fishing activity kills animals that are essential to the aquatic environment, such as corals, and provide food and shelter for a number of marine species. One square meter of coral reef is lost with every fish captured using this method. Also, overfishing has the potential to deplete main reef habitats and damage coral habitat. In many places, rapid human population growth, increased demand, the use of more advanced fishery technology, and insufficient maintenance and regulation have resulted in the extinction of key coral species and habitat damage.

Vikki [24]

Answer:

The correct answer is- iodine

Explanation:

Thyroid glands is an important endocrine gland of the body which release hormone called thyroid hormone in the blood. It plays an important role in metabolism, brain development, and function, muscle control, etc.

The active form of thyroxine is triiodothyronine and the formation of thyroid hormone requires the availability of iodine. Four iodine atoms are present in thyroxine and 3 is present in triiodothyronine. Without iodine, they can not be produced.  

Therefore iodine is the essential element that is required for the manufacturing of thyroxine and triiodothyronine.
