Question
Chapter 33.8, Problem 2LO
Summary Introduction
To explain: The life cycle of a nematode and how it produces disease in humans.
Introduction: Bilaterians are animals with bilateral symmetry, which means the left and right sides of the embryo are mirror images. The bilateral symmetry allowed these animals to achieve high levels of specialization within parts of their bodies, such as the concentration of sensory structures at the anterior phores is truly bilateral.
