| 3. | Lower percentage of protein |
| 4. | (2) and (3) |

| 2. | Both (A) & (R) are true but (R) is not the correct explanation of (A) |
| 3. | (A) is true statement but (R) is false |
| 4. | Both (A) and (R) are false statement |
Milk is produced by which cells?
| 1. | Alveoli | 2. | Lobes |
| 3. | Tubules | 4. | Nipple |
Milk produced by alveoli is stored in
| 1. | Lobes | 2. | Lumen |
| 3. | Duct | 4. | Glandular Tissue |
Mammary glands are not
| 1. | Paired structure |
| 2. | Having glandular tissue |
| 3. | Having defined amount of fat |
| 4. | Characteristic of all female mammals |
The glandular tissue of each breast is divided into
| 1. | 10-12 mammary lobes | 2. | 15-20 mammary lobes |
| 3. | 23-25 mammary lobes | 4. | 25-30 mammary lobes |
Mammary lobe does not have
| 1. | Alveoli | 2. | Mammary tubules |
| 3. | Lumen | 4. | Lactiferous Duct |
Which of the following sequences is correct?
1. Lobes- Mammary Duct- Ampulla- Lactiferous Duct
2. Alveoli- tubules-Lactiferous Duct-Mammary Ducts
3. Mammary Ducts- Lactiferous Ducts- Ampulla- Nipple
4. Mammary lobes- lactiferous Duct- Mammary duct- Nipple
