The competitive exclusion principle states that a) two species cannot coexist in the same habitat. b) competition between two species always causes extinction or emigration of one species. c) competition in a population promotes survival of the best-adapted individuals. d) two species with the exact same niche cannot coexist in a community. e) species that compete usually coevolve.

The competitive exclusion principle states that D) two species with the exact same niche cannot coexist in a community.

This is because they would be both fighting for the same resource and therefore one species would starve the other species out or destroy the other species.

answer >   yes we do, women; have three holes, urethral opening(pee hole, vagina, and the women pee/girls pee out of the urethra like the men do; only they have a single opening to pee/ejaculate.   (sorry if i'm too forward with this, but this is for a biology class, isn't it? )

hope that !         : )
