One very special feature in the earthworm Pheretima is that
1 It has a long dorsal tubular heart
2 Fertilization of eggs occurs inside the body
3 The typhlosole greatly increases the effective absorption area of the digested food in the intestine
4 The S-shaped setae embedded in the integument are the defensive weapons used against the enemies
Explanation:
In Pheretima, intestine is long thin walled tube extending from \({\rm{1}}{{\rm{5}}^{{\rm{th}}}}\) segment to the last. \({{\rm{2}}^{{\rm{nd}}}}\) or middle part of the intestine lies between \({\rm{2}}{{\rm{7}}^{{\rm{th}}}}\) segment upto 23-25 segments in front of anus. This is char-acterized by presence of highly glandular and vascular longitudinal ridge, arising as a median in growth of the dorsal aspect of the intestinal cavity. This is called as Typhlosole and it increases the effective absorp-tion area of digested food in intestine.

Blood glands are present on which segments of the earthworm?
1 \({{\rm{1}}^{{\rm{st}}}}\), \({{\rm{2}}^{{\rm{nd}}}}\) and \({{\rm{3}}^{{\rm{rd}}}}\)
2 \({{\rm{3}}^{{\rm{rd}}}}\), \({{\rm{4}}^{{\rm{th}}}}\) and \({{\rm{5}}^{{\rm{th}}}}\)

4 \({{\rm{5}}^{{\rm{th}}}}\), \({{\rm{6}}^{{\rm{th}}}}\) and \({{\rm{7}}^{{\rm{th}}}}\)
Explanation:
Blood glands are present on the \({{\rm{4}}^{{\rm{th}}}}\), \({{\rm{5}}^{{\rm{th}}}}\) and \({{\rm{6}}^{{\rm{th}}}}\) segments of the earthworm. These produce blood cells and haemoglobin, which are dissolved in blood plasma.
