Answer 1

Answer:

Your answer is as follows:

1. Swollen neck is a symptom of goitre, which is caused by iodine deficiency. Since Iodine is essential to thyroxine hormone produced by the thyroid gland, it's deficiency causes the gland to swell up, which appears to us as a swollen neck.
2. Over secretion of growth hormone during childhood causes gigantism, which results in the patient becoming excessively grown in height.
3. Facial hair in boys at the age of 13, is the natural result of the testosterone hormone, secreted during puberty.
