Which one of the following is common in annelida and arthropods?
1 basal nerve cord
2 ventral nerve cord
3 dorsal nerve cord
4 anterior nerve cord
Explanation:
B The nervous system of Annelida resembles that of Arthropoda, both have metameric segmentation. The nervous system is basically represented by ganglia, arranged segment wise on the ventral nerve cord. Ventral nerve cords are found in some phyla particularly in the Nematodes, Annelids, and Arthropods.

Annelids have a central nerve cord that is :
1 impermeable to $\mathrm{K}^{+}$
2 hollow
3 dorsal
4 ventral
Explanation:
D Annelids have a central nerve cord that is ventral. - The ventral nerve cord is a collection of nerve fibers that runs along the longitudinal axis of various phyla of elongated invertebrates and is a component of the invertebrate central nervous system. It is normally a solid double-strand (pair) of nerve cords. - Chordates animals have a dorsal, hollow nerve cord.

Which of the following assists in the locomotion of the organism stated?
1 Epithelium of Pheretima
2 Trichocysts of Paramecium
3 Pedicellariae of Star fish
4 Posterior sucker of Hirudinaria
Explanation:
D The Hirudinaria posterior sucker helped the organism for locomotion. It performed looping and crawling movements with the aid of muscles and suckers. Suckers and muscles are necessary for sttachment. attache

Pheretima and its close relatives derive nourishment from:
1 Soil insects
2 Small pieces of fresh fallen leaves of maize, etc
3 Sugarcane roots
4 Decaying fallen leaves and soil organic matter
Explanation:
D Pheretima and its related species feed on the decomposing organic matter in the soil. They consume the leftover plant and animal materials as well, thus they are omnivorous.

Which one of the following structure in pheretima is correctly matched with its function:
1 Typhlosole-storage of extra nutrients
2 Clitellum-secretes cocoon
3 Gizzard-absorbs digested food
4 Setae-defence against predators
Explanation:
B Clitellum is a girdle which contains gland cells that emit a material that dries up to form the cocoon from which the egg and sperms are released to assure fertilization. The earthworms embryo grows inside the cocoon. - The glandular tissue clitellum present in 14-16 segments forming a thick girdle. The gland secretes mucus and albumin and form cocoon.
