Which of these is NOT an advantage of the arthropod exoskeleton?
A
Offers structural support for muscle attachment
B
Prevents desiccation in terrestrial environments

Provides protection against predators
D
Allows for unlimited growth without molting
Verified step by step guidance
1
Understand the function of an exoskeleton: The exoskeleton in arthropods serves multiple purposes, including providing structural support, protection, and preventing water loss.
Consider the process of molting: Arthropods must molt, or shed their exoskeleton, to grow. This is because the exoskeleton is rigid and does not expand as the organism grows.
Evaluate the options: The exoskeleton offers structural support, prevents desiccation, and provides protection, but it does not allow for unlimited growth without molting.
Identify the incorrect statement: Since the exoskeleton requires molting for growth, the statement 'Allows for unlimited growth without molting' is not an advantage.
Conclude that the correct answer is the statement that contradicts the known limitations of the exoskeleton, which is the need for molting to accommodate growth.
