| 2. | (D) | Smooth muscle tissue | Heart | Heart contraction |
| 3. | (A) | Columnar epithelium | Nephron | Secretion and absorption |
| 4. | (B) | Glandular epithelium | Intestine | Secretion |
Which one of the following is the true description of an animal concerned?
| 1. | Cockroach – 10 pairs of spiracles (2 pairs on thorax and 8 pairs on abdomen) |
| 2. | Earthworm – The alimentary canal consists of a sequence of pharynx, oesophagus, stomach, gizzard, and intestine |
| 3. | Frog – Body divisible into three regions -head, neck, and trunk |
| 4. | Rat – Left kidney is slightly higher in position than the right one |
Which one of the following is not an example of smooth muscle?
(1) Arrector pili associated with hair follicles
(2) Circular muscle in the wall of intestine
