Answer» 1).Wind act as a pollinating agent because pollen grains are very light and wind can carry them away. The wind carriers away pollen from anther and transfer them on stigma of flowers and hence help in pollination. 2) Variation is beneficial for the existence of the species because they play an important role in the adaption to survive in the changing conditions. Variation is not essential for an individual because it doesn't help in the evolution of a human being or a person.. Condoms prevent entry of sperms into the vagina hence it prevents pregnancy |
