1 Two pair of testis is present in \(10^{\text {th }}\) and \(11^{\text {th }}\) segment
2 One pair of ovaries in attached at the intersegmental septum of the \(12^{\text {th }}\) and \(13^{\text {th }}\) segment
3 It is hermaphrodite
4 Male genital pore is present in \(14^{\text {th }}\) segment
Explanation:
D A pair of male genital pores are present on the ventro-lateral sides of the 18 th segment. A single female genital pore is present in the mid ventral line of 14 th segment.

In earthwormthe characteristic internal median fold of dorsal wall of the intestine called typhlosole is present in
1 5 to 9 segments
2 9 to 14 segments
3 26 to 35 segments
4 15 to last segment
5 35 to last segment
Explanation:
C 26 to 35 segment is the present of internal median fold of dorsal wall of the intestine called typhlosole. This increases the area of absorption in the intestine.

Specialised chemoreceptors located on the anterior part of earthworms are
1 heat receptors
2 photo receptors
3 taste receptors
4 pressure receptors
5 auditory receptors
Explanation:
C Specialised chemoreceptors located on the anterior part of earthworms are taste receptors indeedearthworms are known to have chemoreceptors principally on the prostonium or on the buccal epithelium that are associated with the nervous system and more particularly with axons and dendrites.

What is common between earthworm and Periplaneta?
1 Both have red coloured blood
2 Both possess and styles
3 Both have malpighian tubules
4 Both have segmented body
Explanation:
D The body of earthworm shows metameric segmentationwhile in periplaneta it is externally segmented. They inhabits the upper layer of the moist soilwhile in periplanetabody is externally segmented and live in damp place both are non-chordates. - Segmentation is mostly external in arthropods and mainly internal in man and other chordates.
