Question

which trace mineral found in fish and shellfish is important for normal thyroid function and its lack can cause hypothyroidism? a.) iron b.) manganese c.) iodine d.) fluoride

Explanation:

Iodine is a trace mineral crucial for thyroid hormone synthesis. Thyroid hormones regulate metabolism, growth, and development. Hypothyroidism occurs when the thyroid gland doesn't produce enough hormones, often due to iodine deficiency. Fish and shellfish are good dietary sources of iodine. Iron is for red blood cells (anemia if deficient), manganese for enzyme functions, and fluoride for teeth/bones.

Answer:

C. Iodine
