The wings of bat, locust and pigeon are the examples of
1 vestigial organs
2 analogous organs
3 homologous organs
4 exoskeletal structure
Explanation:
The wings of bat, locust and pigeon are the examples of analogous organs. The organs which have similar functions but are different in their structural details and origin are called analogous organs. The analogous structures are the result of convergent evolution.

Birbal Sahni worked on
1 alage
2 bryophytes
3 fossil plants
4 angiosperms
Explanation:
Birbal sahni was an Indian paleobotanist, worked on fossil plants of Indian sub-continent. He also took an interest in geology and archaeology. He is known as 'Father of Indian paleontology'. He studied anatomy and morphology of Paleozoic ferns and also worked on fossil plants of Indian Gymnosperms, the Pentoxylales.

Select vestigial organs from the following.
1 Vermiform appendix, wings of bat and coccyx of man.
2 Vermiform appendix, nictitating membrane and coccyx of man.
3 Forelimbs of whale, lizard and bat.
4 Wings of bat, nictitating membrane and wings of insects.
Explanation:
The organs which are present in reduced from and do not perform any function in the body but correspond to the fully developed functional organs of related animals are called vestigial organs. They are believed to be remnants of organs which were complete and functional in their ancestors. Human body possess about 90 vestigial organs. Some of these are nictitating membrane (Plica semilunaris), auricular muscles (muscles of Pinna), segmental muscles of abdomen, ponniculus carnosis (subcutaneors muscles), vermiform appendix, caudal vertebrae (also called coccyx or tail bone), third molar (wisdom teeth) hair on body, and Nipples in male.

Cosmozoic theory was proposed by :
1 Helmholtz
2 Richter
3 Pasteur
4 Arrhenius
Explanation:
The theory was proposed by Richter (1865). According to this theory, protoplasm reached the earth in the form of spores or germs or other simple particles from some unknown part of the universe with the cosmic dust, and subsequently evolved into various forms of life. Arrhenius (1908, Nobel prize winner of 1903 in chemistry) postulated the Panspermia theory and stated that organisms existed throughout the universe and their spores etc could freely travel through space from one star to the others. In fact, panspermia theory is the alternative name of cosmozoic theory.
