Being that we just put an end to chapter 35 we are drawing nearer and nearer to the end of out course work, this therefore puts pressure on how well you understood the chapters before and including chapter 35. If you...

Questions: 11 | Attempts: 797 | Last updated: Mar 16, 2025

Sample Question 1
Which phylum contains the vertebrates?

Arthropoda

Chordata

Annelida

Mollusca

Porifera

Sample Question 2
A notochord is

A strip of cartilage that forms a back and tail in all vertebrates.

Cells surrounded by a sheath to form a stiff dorsal supporting rod.

A primitive form of bone vertebra that develops into the backbone.

The early nerve structure that becomes the spinal cord.

All of the above are correct.

Sample Question 3
Although several groups have been proposed as the chordate ancestors, embryological evidence indicates the chordates have probably descended from the

Ectoproct larvae.

Trochophore larvae of Mollusca.

Echinoderm larvae.

Primitive forms of Obelia in the phylum Cnidaria.

Ancestors similar to larval dragonflies in the phylum Arthropoda.
