Assertion : Moths living in the industrial area became dark to match body colour to the tree trunks Reason : Smoke from industries covers the moths, making them appear dark
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect.
Explanation:
Industrial Melanism is the increase of melanic (black) forms of animals in areas darkened by industrial pollution. Common examples is peppered moth which existed in 2 strains (Black and white)

Which of the following set of structures includes only analogous organs?
1 Hind legs of horse
2 Wings of butterfly, housefly and bat
3 Hands of man, monkey and kangaroo
4 Mandibles of cockroach, mosquito and honeybee
Explanation:
Wings of butterfly, housefly, and bat perform same function but they are different anatomically.

Analogous organs arise due to
1 Divergent evolution
2 Artificial selection
3 Genetic drift
4 Convergent evolution
Explanation:
The organs which have similar functions but are different in their structural details and origin are called analogous organs. The analogous structures are the results of convergent evolution. The wings of an insect are analogous to wings of a bird. It is due the fact that the basic structure of the wings of the insects is different from the wings of bird. However, their function is similar.

Which of the following is used as an atmospheric pollution indicator
1 Lepidoptera
2 Lichens
3 Lycopersicon
4 Lycopodium
Explanation:
Lichens can be used as an atmospheric pollution indicator as they are sensitive to oxides of nitrogen and sulphur can't grow well.
