Explanation:
Correct option: 2. A-IV, B-III, C-II, D-I.
CCK (A) is secreted mainly by the intestinal mucosa and acts on the pancreas to stimulate enzyme secretion (pancreas) — A with IV. GIP (B) is the gastric inhibitory peptide released by K-cells in the intestine and is associated with the gastric region; NCERT echoes its action on gastric glands, hence B with III. ANF (C) is secreted by the heart and acts on the kidney to promote natriuresis and diuresis — C with II. ADH (D) is released from the posterior pituitary and targets the kidney to increase water reabsorption — D with I.
🧠 Did You Know?
In NCERT, GIP is described as gastric inhibitory peptide because it inhibits gastric secretion and motility, while also promoting insulin release from the pancreas.
💡 NCERT Memory Line:
CCK → pancreas; GIP → pancreas (insulin release) but linked to gastric region in some classifications; ANF → heart (acts on kidney); ADH → kidney.
Which of the following are NOT under the control of thyroid hormone?
A.Maintenance of water and electrolyte balance.
B.Regulation of basal metabolic rate.
C.Normal rhythm of sleep-wake cycle.
D.Development of immune system.
E.Support the process of R.B.Cs formation.

AI-generated explanation. Check against your textbook.
Explanation:
Thyroid hormone mainly controls basal metabolic rate and supports growth and development. It does not regulate the sleep–wake rhythm (which is governed by the hypothalamus/pineal gland and melatonin) or the immune system development. Water and electrolyte balance is maintained by kidneys and hormonal controls like ADH/aldosterone, not thyroid hormone. RBC formation is controlled by erythropoietin from kidneys, not thyroid hormone. So the statements not under thyroid control are C and D.
🧠 Did You Know?
NCERT emphasizes the primary roles of thyroid hormones in metabolism and development, while sleep regulation and immune development involve other regulatory systems.
💡 NCERT Memory Line:
Thyroid hormone regulates metabolic rate and growth, not the sleep–wake cycle or immune system development.
Which of the following are not the effects of
Parathyroid hormone?
A.Stimulates the process of bone resorption
B.Decreases Ca2+ level in blood
C.Reabsorption of Ca2+ by renal tubules
D.Decreases the absorption of Ca2+ from digested food
E.Increases metabolism of carbohydrates
Choose the most appropriate answer from the
options given below:
Match the following columns and select the
correct option.
Column-I
Column-II
(A)Pituitary gland
(I)Grave's disease
(B)Thyroid gland
(II)Diabetes mellitus
(C)Adrenal gland
(III)Diabetes insipidus
(D)Pancreas
(IV)Addison's disease
AI-generated explanation. Check against your textbook.
Explanation:
Match: Pituitary gland – Diabetes insipidus (III) due to ADH deficiency; Thyroid gland – Grave's disease (I) as a common hyperthyroidism; Adrenal gland – Addison's disease (IV) from adrenal insufficiency; Pancreas – Diabetes mellitus (II) due to insulin deficiency or action. Therefore the correct pairing is (A)-(III), (B)-(I), (C)-(IV), (D)-(II).
🧠 Did You Know?
NCERT explains that pituitary hormones regulate water balance, thyroid hormones regulate metabolism, adrenal cortex hormones regulate stress and metabolism, and pancreatic insulin regulates blood glucose.
