| 3. | Trachea | 4. | Fallopian tube | 
| Assertion (A): | Compound epithelium has a limited role in secretion and absorption. | 
| Reason (R): | Their main function is to provide protection against chemical and mechanical stresses. | 
| 1. | Both (A) and (R) are True and (R) explains (A) | 
| 2. | Both (A) and (R) are True and (R) does not explain (A) | 
| 3. | (A) is True but (R) is False |

| 3. | (A) is True; (R) is False | 
| 4. | Both (A) and (R) are False | 
| A. | Microvilli in the proximal convoluted tubule (PCT) of the nephron increase surface area for filtration. | 
| B. | Simple columnar epithelium is composed of multiple layers of tall, slender cells with nuclei at the base, primarily aiding in protection. | 
| C. | Ciliated epithelium is found lining the bronchioles and fallopian tubes, where it moves particles or mucus in a specific direction. | 
| D. | Cuboidal epithelium in the PCT of the nephron mainly facilitates mucus secretion rather than absorption. |

The following histology section depicts the structure of:
| I: | The male frog has a pair of testes which are attached to the kidneys by a structure called mesorchium. | 
| II: | The male frog's sperm travels through the urethra which also carries urine. | 
| III: | External fertilization occurs, and the frog's sperm are released directly into the surrounding water. |
