Answer:
Adult tape worm
Step-by-step explanation:
An adult tapeworm consists of a head, neck and chain of segments called proglottids. When you have an intestinal tapeworm infection, the tapeworm head adheres to the intestinal wall, and the proglottids grow and produce eggs. Adult tapeworms can live for up to 30 years in a host.
Intestinal tapeworm infections are usually mild, with only one or two adult tapeworms. But invasive larval infections can cause serious complications.
