3. The complexity of structure and function varies widely across the animal kingdom. Despite this variation, animals exhibit common processes. These include the following. • transport of materials
• response to stimuli
• gas exchange
• locomotion

(a) Choose two of the processes above and for each, describe the relevant structures and how they function to accomplish the process in the following phyla.
Cnidaria (e. g., hydra, jellyfish)
Annelida (e. g., earthworm)
Chordata (e. g., mouse)

(b) Explain the adaptive (evolutionary) value(s) of the structural examples you described in part a.
