Forelimbs of whatle bat, cheetah and duman do not show- a. Similiarities in the pattern of bones b. Adaptive radiation c. Analogou organs d. Convergent evolution e. Divergent evolution f. Different structuress evolving for sam funstions

Assertion :- Analogous structures are a result of convergent evolution. Reason :- Different strutures evolving for the same function and hence having similarity.

Assertion :- All mammals like whales, bats cheetah and human etc. share similarities in the pattern of bonse of forelimbs. Reason :- Eutherians show good example of divergent evolution.

Read the following statements regarding evolution (A-D)- A. Whales, bats, cheetah, and humans (all mammals) share similarities in the pattern of bones of forelimbs. B. The diversity of life forms on earth has been changing over millions of years. C. About 65 million years ago the dinosaurs suddenly disappeared from the earth. D. A single-step large mutation is called speciation and explained by Herbert Spencer. How many statements from the above is/are correct ?

A. The conditions primitive on earth (before the origin of life) were : low temperature, volcanic storms, reducing atmosphere containing Ch_(4),NH_(3) , etc. B. Cheetah and humans share similarities in the pattern of bones of forelimbs. C. In a collection of moths made in the 1850s i.e., before industrialization set in, it was observed that there were more dark-winged moths on trees than white-winged moths. D. Branching descent and natural selection are the two key concepts of Darwinian theory of evolution. E.

Given below are assertion and reason. Point out if both are true with reason being correct explanation (A), both true but reason is not correct explanation (B), assertion true but reason is wrong ( C ), both are wrong (D). Assertion : Analogous organs are a result of divergent evolution Reason : Eye of Octopus and that of mammals depict divergent evolution.

Eight friends - A, B, C, D, E, F, G and H - are sitting around a circular table facing the centre but not necessarily in the same order. Each of them likes a different cricketers - Dhoni, Yuvraj, Sachin, Dravid, Irfan, Suhail, Ashwin and Michael.

A, who likes Ashwin, sits second to the right of the girl who likes Michael. B and E neither like Michael nor sit adjacent to A. E, who likes Yuvraj, sits second to the left of G, who likes Dravid. C does not like Dhoni. The immediate neighbour of E faces C, who sits third to the left of the one who likes Ashwin. F does not like Michael. Both D and H do not like Dhoni and Sachin. B likes Suhaib while D likes Irfan. Is not an immediate neighbour of A. Four of the following five are alike in a certain way based on the given arrangement and thus form a group .
