| 1. | are all proteins. |
| 2. | can have a long lasting effect on their target cells. |
| 3. | are not transported by blood. |
| 4. | provide a point-to-point rapid coordination among organs |

Consider the two statements:
| 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). |
| 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. | Both (A) and (R) are False. |
