Answer Details

Tapeworms are a type of parasitic flatworm that infect livestock such as cows, sheep, and pigs. They possess proglottides, which are segments that make up the body of the tapeworm. Each proglottid contains reproductive organs and can produce eggs, which are shed in the feces of the host.
Proglottides enable tapeworms to reproduce and increase their population within the host's digestive system. They can grow up to several meters long and cause various health problems, including malnutrition and reduced productivity in livestock.
