I need help with these following questions if you could help me I would appreciate it so much.   1)In adapting to a parasitic lifestyle, parasites develop extremely fertile reproductive systems.  Why? 2)Endoparasites also have simple sensory systems.  Why? 3)Why does Paragonimus westermanni have such a complex reproductive system and such a huge reproductive potential? 4)Why is it that the developed countries of the world have fewer problems with parasitic diseases than the underdeveloped countries? Consider economics, technology, and the biology of the parasites as part of your answer.
