Select the correct route for the passage of sperms in male frogs:
1. | Testes → Vasa efferentia → Kidney → Seminal Vesicle → Urinogenital duct → Cloaca |
2. | Testes → Vasa efferentia → Bidder's canal → Ureter → Cloaca |
3. | Testes → Vasa efferentia → Kidney → Bidder's canal → Urinogenital duct → Cloaca |
4. | Testes → Bidder's canal→ Kidney→ Vasa efferentia → Urinogenital duct→ Cloaca |
Which type of tissue is correctly matched with its location?
Tissue | Location | |
1. | Areolar tissue | Tendons |
2. | Transitional epithelium | Tip of nose |
3. | Cuboidal epithelium | Lining of stomach |
4. | Smooth muscle | Wall of intestine |
The function of the gap junction is to?
1. | Perform cementing to keep neighbouring cells together |
2. | Facilitate communication between adjoining cells by connecting the cytoplasm for rapid transfer of ions, small molecules and some large molecules |
3. | Separate two cells from each other |
4. | Stop substances from leaking across a tissue |

1. Without nucleus but with haemoglobin
2. Nucleated and with haemoglobin
3. Very much smaller and fewer
4. Nucleated and without haemoglobin

Which of the following animal is correctly matched to their corresponding respiratory organ ?

haemoglobin
2. Cockroach - Three pairs of spiracles in each
thorax
3. Frog in water - Skin and lungs

Which of the following statements is not correct with respect to the epithelial tissue?
1. It covers the external surface of the body and the internal surface of many organs.
2. The neighbouring cells are held together by cell junctions and there is very little intercellular material.
3. The epithelial cells rest on a cellular basement membrane that separates it from underlying connective tissue.
4. There is no blood vessel supplying the nutrients to the epithelial cells.

3. cardiac muscle
4. skeletal muscle
Which of the following is mismatched?
1. matrix - extracellular material in connective tissue
2. cardiac muscle cells - uninucleate.
3. chondrocytes - cartilage cells
4. ligaments - bind muscles to bone
