The segments of a tapeworm consisting primarily of eggs, which hang in bags as a long chain behind the head, are called scolexes. cercariae. glycocalyxes. proglottids. sporocysts.

The answer is proglottids.

When tapeworm infect the intestine, it will attach a segment that consist of a part with many eggs called proglottids. The proglottids will constantly produce eggs. If the worm is removed but some of the proglottid leave behind, the infection would be recur, so it is important to remove all proglottid

the fossil record provides evidence of a common ancestor to many species.
