Answer 1

Answer:

.....

Cestoda is the class of parasitic flatworms which include tapeworms. They have no gut and no digestive system. They simply absorb nutrients from their host's gut. They are endoparasite and hermaphrodite.

Cestodes are covered with a cuticle (tough but flexible, non-mineral covering), and lack a true circulatory or respiratory system; they do have a bilateral nervous system. They respire anaerobically.
