What happens during human reproduction?

Fertilization happens high up in the Fallopian tube. If a sperm penetrates the egg, an embryo will begin to form. This happens through cell division: one cell becomes two, which become four, which become eight, and so forth. i hope this is helpful!

If I'm incorrect please comment below :P

a scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. a scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.

fumikage isn't really a bird, and tsuyu does have teeth. tsuyu has a transformation quirk which still allows her to be partially human. otherwise we'd have a large frog running around. fumikage has teeth because again, he isn't a bird. his head was a quirk mixture if i'm correct.
