Question: Don't the impregnated hosts have to be alive in order to incubate the aliens to term? Lex kills the impregnated Italian guy to prevent him have the Alien rip out of his chest, which would imply that the Alien needs to be in a living environment to survive. Not the case with the Alien/Predator hybrid that emerges at the end of the movie, when it's clear that the Predator had died some time ago . . .

Answer: Killing the host doesn't necessarily kill the Alien. Its like human fetuses - if it is far enough along in its development, it can survive even if the host (mother) dies.
