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. |
