Molecular comparisons place nematodes and arthropods in clade Ecdysozoa. What characteristic do they share that is the basis for the name Ecdysozoa? a. a complete digestive tract b. body segmentation c. molting of an exoskeleton d. bilateral symmetry

Verified step by step guidance

1. Identify the key term in the question, which is 'Ecdysozoa'. Understanding what this term means will help in determining the shared characteristic between nematodes and arthropods.
2. Recall the definition of 'Ecdysozoa'. This clade includes organisms that grow by molting, a process known as ecdysis, which involves shedding their exoskeleton to allow for further growth.
3. Analyze the answer choices in relation to the definition of ecdysis. Look for an option that directly relates to the process of molting or shedding an exoskeleton.
4. Eliminate the options that do not specifically relate to the process of molting. Options that mention other general biological features like digestive tracts, body segmentation, or symmetry should be considered less likely.
5. Select the answer that specifically mentions molting or an exoskeleton, as this directly correlates with the defining characteristic of the Ecdysozoa clade.
