| (a) | Stimulates the process of bone resorption. |
| (b) | Decreases Ca2+ level in blood. |
| (c) | Reabsorption of Ca2+ by renal tubules. |

Normal sleep-wake cycle in a human body is maintained by the secretion of:
1. Thyroid gland
2. Thymus gland
3. Pineal gland
4. Pituitary gland
| Statement I: | On the basis of their chemical nature, hormones can be divided into group i. Peptide, Polypeptide, protein hormones ii. Steroids iii. Iodothyronines iv. Amino acid derivatives |
| Statement II: | underproduction of hormones by adrenal cortex alters carbohydrate metabolism causing acute weakness and fatigue leading to disease called diabetes mellitus |
| Assertion (A): | FSH which interacts with membrane bound receptors does not enter the target cell. |
| Reason (R): | Binding of FSH to its receptors generates second messenger (cyclic AMP) for its biochemical and physiological responses. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | (A) is False but (R) is True. |
| Assertion (A): | Apart from the organised endocrine glands, hormones are secreted by other parts of the human body as well. |
| Reason (R): | Hormone is any non-nutrient chemical which acts as intercellular messenger and is produced in trace amounts. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
