Answer:

A) Longitudinal but no circular muscles;

B) Separate male and female individuals;

C) Shedding of the integument;

D) A tough, collagen-based cuticle

  • The posses longitudinal muscles in their body walls
  • They exhibit sexual dimorphism, that is, male and female occur separately
  • They posses tough cuticle/integument which periodically moults
  • They exist as either free-living or parasites of man and various animals. E.g Ascaris lumbricoides
