a-ii-r Syphilis is a sexually transmitted disease caused by bacterium Treponema pallidum. b-iv-p Reversible sterilization is a surgical technique that prevents the passage of sperms through vasa deferentia in males. It is called reversible because by another surgical procedure the passage-way can be restored. The technique is called vasectomy. c-i-s Geitonogamy is a type of self-pollination where the transfer of pollen to the stigma takes place between two flowers of the same plant. d-iii-q Air layering is a method of propagating new plants from stems still attached to the parent plant. It is a type of vegetative propagation which can be seen in pomegranate plant. Sl.Order Column I Sl.No Column II Serial Order Column III (a) STD (ii) Syphilis r.
