erica [24]

Thyroid hormone contains the mineral iodine (option I). Details about thyroid hormone can be found below.

<h3>What is the thyroid hormone?</h3>

Thyroid hormone is the hormone produced by the thyroid gland of the body, which is a large butterfly-shaped endocrine gland situated on the front of the neck that produces various hormones.

The thyroid hormone is responsible for regulating metabolism, which controls the amount of calories burnt in a day.

One of the major minerals found in the thyroid is iodine. The thyroid gland absorbs iodine from the bloodstream, and then stores it to aid in the production of thyroid hormones.

Therefore, the thyroid hormone contains the mineral iodine.
