Answer 2

Answer:

Vestigial organs are those organs which once were functional but now they don't have any function in human body

Vestigial organs are appendix , nictitating membrane of eyes , wisdom teeth etc.

Appendix in human is non functional but in some domestic animals like buffaloes and cows it's functional because its function is to digest cellulose , which is found in plants cell wall but human can't digest cellulose now because of non functional appendix ｡◕‿◕｡
