Q. No.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 |
Choose the correctly matched pair:
1. Tendon-Specialized connective tissue
2. Adipose tissue-Dense connective tissue
3. Areolar tissue- Loose connective tissue
4. Cartilage- Loose connective tissue
Choose the correctly matched pair:
1. Inner lining of salivary ducts- Ciliated epithelium
2. Moist surface of buccal cavity- Glandular epithelium
3. Tubular parts of nephrons- Cuboidal epithelium
4. Inner surface of bronchioles- Squamous epithelium
| 1. | Smooth muscles, show branching, found in the walls of the heart |
| 2. | Cardiac muscles, unbranched muscles, found in the walls of the heart |
| 3. | Striated muscles, tapering at both ends attached to the bones of the ribs |
| 4. | Skeletal muscle, shows striations and is closely attached to the bones of the limbs |
Compared to those of humans, the erythrocytes in frogs are:
1. Without nucleus but with haemoglobin
2. Nucleated and with haemoglobin
3. Very much smaller and fewer
4. Nucleated and without haemoglobin
The supportive skeletal structures in the human external ears and the nose tip are examples of:
1. Areolar tissue
2. Bone
3. Cartilage
4. Ligament
Given below is the diagrammatic sketch of a certain type of connective tissue. Identify the parts labeled A, B, C, and D and select the right option for them:
| Part-A | Part-B | Part-C | Part-D | |
| 1. | Mast cell | Macrophage | Fibroblast | Collagen fibres |
| 2. | Macrophage | Collagen fibres | Fibroblast | Mast cell |
| 3. | Mast cell | Collagen fibres | Fibroblast | Macrophage |
| 4. | Macrophage | Fibroblast | Collagen fibres | Mast cell |
The four sketches (A, B, C, and D) given below, represent four different types of animal tissues. Which one of these is correctly identified in the options given, along with its correct location and function?
| Tissue | Location | Function | ||
| 1. | (C) | Collagen fibres | Cartilage | Attach skeletal muscles to bones |
| 2. | (D) | Smooth muscle tissue | Heart | Heart contraction |
| 3. | (A) | Columnar epithelium | Nephron | Secretion and absorption |
| 4. | (B) | Glandular epithelium | Intestine | Secretion |
| 1. | the typhlosole greatly increases the effective absorption area of the digested food in the intestine |
| 2. | the S-shaped setae embedded in the integument are the defensive weapons used against the enemies |
| 3. | it has a long dorsal tubular heart |
| 4. | fertilization of eggs occurs inside the body |
