The disease which is caused by the deficiency of thyroxine:
Correct answer: B. Goiter
- A. Grave's disease
- B. Goiter
- C. Hyperglycemia
- D. Dwarfism
Explanation
Hyperglycemia is caused by under production of insulin hormone. Option B is correct as iodine deficiency is the most common cause of goiter. The body needs iodine to produce thyroid hormone. If you do not have enough iodine in your diet, the thyroid gets larger to try and capture all the iodine it can, so it can make the right amount of thyroid hormone.

About Chemical Coordination and Hormones
Chemical coordination uses hormones released by endocrine glands and carried in blood to specific target cells. Coverage includes the pituitary, thyroid, pancreas, adrenal glands, ovaries and testes, feedback control, and the contrast between slower, longer-lasting hormonal responses and rapid nervous coordination.
