Which of the following is true?
1 Human hands and bats wings are analogous organs
2 Flipper of seal and wing of birds are homologous organs
3 Wings of birds and insects are homologous organs
4 Human hands and birds wings are analogous organs
Explanation:
Flipper of seal and wing of birds are homologous organs i.e they are having same structure but different function. Both the flipper of seal and wings of birds are modified limbs, but Flippers are helpful in swimming while the wings are meant for flying.

Which one of the following pairs of items correctly belongs to the category of organs mentioned against it?
1 Wings of honey bee and wings of crow - Homologous organs
2 Thorn of bougainvillea and tendrils of cucurbita - Analogous organs
3 Nictitating membrane and blind spot in human eye - Vestigial organs
4 Nephridia of earthworm and malpighian tubules of cockroach - Excretory organs
Explanation:
Wings of honey bee and wings of crow Analogous organs Thorn of Bougainvillea and tendrils of cucurbita - Homologous organs Nictitating membrane and blind spot in human eye - Both are not vestigial organs

Tendrils of cucurbita and thorns of bougainvillea are examples of
1 Vestigial organs
2 Analogous organs
3 Homologus organs
4 Atavism
Explanation:
Thorns of Bougainvillea and tendrils of Cucurbita are examples of homologous organs. They arise from the axillary buds. They perform different types of functions. The thorn is for providing protection against the grazing animals. The tendrils help in providing support while climbing. They are anatomically similar. But the functions are different.

Evolution by anthropogenic action tells us
1 Evolution is not a directed process in the sense of determinism.
2 It is a non- stochastic process based on chance events in nature and chance mutation in the organisms.
3 It is a stochastic process based on chance events in nature and chance mutation in the organisms.
4 Both 1 and 3
Explanation:
Anthropogenic actions refer to the activities that are caused by human beings. Anthropogenic action also referred to as human activities has commenced to the evolution of a number of new species in a short time scale. This hastens the method of evolution.
