Question

with____deficiency, thyroid hormone production declines, and the body responds by secreting more thyroid - stimulating hormone (tsh) in a futile attempt to accelerate uptake by the thyroid gland.
o a. lodine
o b. zinc
o c fluoride
o d selenium

Explanation:

Iodine is essential for the production of thyroid hormones. A deficiency in iodine leads to reduced thyroid hormone production, prompting the body to secrete more thyroid - stimulating hormone (TSH) to try to increase iodine uptake by the thyroid gland. Zinc, fluoride, and selenium do not have a direct role in this specific mechanism related to thyroid hormone production and iodine uptake by the thyroid gland.

Answer:

a. Iodine
