Chapter 33.9, Problem 3LO
Summary Introduction
To describe: The advantages and drawbacks of an exoskeleton.
Introduction: The members of arthropods are small,usually a few millimeters in length, and the adults range in size from about 80 micrometer long. These organisms consist of segmented body, exoskeleton, and joined appendages. The segments are specialized into
