The pheromones are picked up by receptors on the male beetles and this is how they find the females.
According to Bronsted-Lowry acid concept
an acid is a that donate a proton" and a base is a "proton acceptor."so
will look for that molecule to which <span>H2O</span> "donates" H+to become <span>OH−</span>. so answer will be..
. <span>NH3+H2O→NH+4+O<span>H<span>−
so correct option is NH3
hope it helps</span></span></span>
