Its urgent
Want relevant answers..
Non sense n stupid answers will be reported!!

Answer 1

Homologous organs: organs which have same basic structure but different function.

Example: The forelimbs of a frog,lizard & bird have same basic design of bones but they perform different functions.the forelimbs of lizard used for running & the forelimbs of bird are modified for flying.hence,all these organisms use their forelimbs for performing different function.

Analogous organ: Organs which hv different basic structure but perform similar functions.

Example: the wings of an insect & a bird hv different structure,but they perform the same function of flying.
