Chapter 44.3, Problem 1CC
Summary Introduction
To compare: The ways in which the
Concept introduction: The excretory system varies in the flatworm, earthworms and the insects. The earthworms have metanephridia, protonephridia in flatworms and Malpighian tubules in insects are present for excreting the metabolic wastes.
