An evolutionary pattern characterized by a rapid increase in the number and kinds of closely related species is called
1 convergent evolution
2 divergent evolution
3 adaptive radiation
4 Both (b) and (c)
Explanation:
C In evolutionary biology convergent evolution is defined as the process whereby distantly related organisms independently evolve similar traits to adapt to similar necessities. - Adaptive radiation refers to the diversification of a group of organisms into different from and occupying different ecological niches.

The colour of the body in earthworm is brown due to the presence of
1 Porphyrin
2 haemoglobin
3 blood
4 haemocyanin
Explanation:
A The colour of the body in earthworm is brown due to the presence of porphyrin pigment. - Porphyrins are a group of heterocyclic macrocycle organic compoundscomposed of four modified pyrrole subunits interconnected to their are carbon atoms vill methane bridge.

Four pairs of pulsatile heart in Pheretima are located in segments
1 7912 and 13
2 \(11,14,17\) and 18
3 \(10,13,16\) and 17
4 4510 and 13
Explanation:
A Earthworms belongs to phylum annelida which is triploblastic and has a true coloem. These have segmented body. The hearts in the \(12^{\text {th }}\) and \(13^{\text {th }}\) segements of earthworm are called as lateral esophageal heart. While the anterior pairs in the \(7^{\text {th }}\) and \(9^{\text {th }}\) segment are called as the lateral heart.

In Pheretimalocomotion occurs with the help of :
1 circular muscles
2 longitudinal muscles and setae
3 circularlongitudinal muscles and setae
4 parapodia
Explanation:
C Locomotion in pheretima is carried out by longitudinal and circular muscles. Longitudinal muscles run lengthwise along the body. The circular muscles encircle the body and help in increasing or decreasing the width of the organism.
