A. classification up to class is only spelling practice B. classification up to class applies only to plants C. classification up to class replaces observation D. classification up to class helps identify representative diversity
Correct Answer: D. classification up to class helps identify representative diversity

While comparing invertebrate groups, a phylogeny lecture uses sea stars to explain invertebrate links with vertebrate ancestry. The feature being tested is:

A. echinoderms are protozoans B. echinoderms are molluscs C. echinoderms are cnidarians D. echinoderms are closer to chordates than arthropods in deuterostome relationships
Correct Answer: D. echinoderms are closer to chordates than arthropods in deuterostome relationships

A diagram in the course handout shows that a teacher asks for one developmental clue linking molluscs with annelids. Identify the related structure or process.

A. molluscs and annelids share trochophore larvae in many groups B. molluscs and annelids both have cnidocytes C. molluscs and annelids both lack mesoderm D. molluscs and annelids both have water vascular systems
Correct Answer: A. molluscs and annelids share trochophore larvae in many groups

In a specimen-based viva, the examiner describes this case: a museum practical asks students to compare sponges, cnidarians, flatworms, molluscs, annelids, arthropods, and echinoderms. Choose the concept that fits it best.

A. representative phyla show only colour variation B. representative phyla remove need for taxonomy C. representative phyla show major body plans D. representative phyla are chosen randomly
Correct Answer: C. representative phyla show major body plans
