Microvilli of intestinal epithelium are similar in function with
1 Typhlosole in earthworm
2 Hepatic caecae in cockroach
3 Intestinal caecum in earthworm
4 Malpighian tubules in cockroach.
Explanation:
A Microvilli helps in the absorption of nutrient in the small intestine. - Thousands of microvillus forms a brush border structure that is present on the apical area of epithelium intestine. - Digestive system of earthworm instead of coiling the mid dorsal wall of the intestine forms a longitudinaltongue like fold which is known as typhlosole. - This structure helps in making the absorption of nutrientmore efficient.

Which one of the following correctly describes the location of some body parts in the earthworm (Pheretima)?
1 Four pairs of spermatheca in 4-7 segments
2 One pair of ovaries attached at intersegmental septum of \(14^{\text {th }}\) and \(15^{\text {th }}\) segments
3 Two pairs of testes in \(10^{\text {th }}\) and \(11^{\text {th }}\) segments
4 Two pairs of accessory glands in 16-18 segments
Explanation:
C In pheretima (earthworm) two pairs of testes are present in the \(10^{\text {th }}\) and \(11^{\text {th }}\) Segments. -Each testis is sac of the \(10^{\text {th }}\) segment encloses a testis and seminal Funnel. Each testis sac of the \(11^{\text {th }}\) Segment encloses a testisa seminal vesicle and seminal funnel. - A pair of spermathecae are located in each segment from \(6^{\text {th }}\) to \(9^{\text {th }}\) segments. They are structures that receive sperms after mating. - One pair of ovaries is attached to the intersegmental septum of the \(12^{\text {th }}\) and \(13^{\text {th }}\) segments.

Which one features is common to leechcockroach and scorpion?
1 Nephridia
2 Ventral nerve cord
3 Cephalization
4 Antennae.
Explanation:
B The ventral nerve cord is a cord of nervous tissue that runs the length of the animal in the lower part of its body. It is the common characteristic of lower Chordates likeleechcockroachScorpion. - Nephridia are the excretory organs in annelida like in earthworm and leechcockroachand scorpion. anterior

1 gills of prawn
2 trachea of insects
3 nematoblasts of Hydra
4 flame cells of Planaria
Explanation:
D The nephridiain earthworm are analogous to flame cells of planaria. A pair of nephridia is present on each segment of the earthworm. - A flame cell is specialized excretory cell. These are the simplest animals to have an excretory system flame cells function like a kidney. - Removing waste material flame cells are called protonephrdia.
