Aspecies is a group of organisms capable of mating and producing offspring, and is the process of forming a new species. one way a new species may form is by geographic isolation. this occurs when members of a population are physically separated, for example, by a river, or a desert. after the separation the two populations, responding to different conditions, will adapt differently, and so their evolutionary paths will be different.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .

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 !         : )
