• D. (i) – A, (ii) – C, (iii) – D, (iv) –B

Answer 1

The correct option is D

(i) – A, (ii) – C, (iii) – D, (iv) –B

$\begin{array}{cc}\text{Column A}& \text{Column B}\\ \left(i\right)\text{Lack of iodine}& \left(A\right)\text{Causes goitre}\\ \left(ii\right)\text{Person whose blood glucose is very high}& \left(B\right)\text{Diabetic}\\ \left(iii\right)\text{Lack of growth hormone}& \left(C\right)\text{Causes dwarfism}\\ \left(iv\right)\text{Responsible for puberty in females}& \left(D\right)\text{Estrogen}\end{array}$

(i)An amino acid tyrosine and iodine are involved in the formation of thyroid hormone. The hormones secreted by the thyroid gland are Triiodothyronine (T3) and Tetraiodothyronine or Thyroxine (T4)

(ii)The deficiency of insulin causes Diabetes mellitus. It is characterised by increase in blood sugar level (Hyperglycemia).

(iii)GH promotes the development and enlargement of all tissues of the body. Dwarfism is caused by decreased secretion of growth hormone in children.

(iv)Estrogen is produced by the Graafian follicles of the ovary. It brings about the changes that occur during puberty. It initiates the process of oogenesis.
