3) A robin has difficulty pulling an earthworm from its earthen burrow because of small chitinous bristles called

1. A) parapodia.
2. B) segments.
3. C) annuli.
4. D) metanephridia.

4) The circulatory system of earthworms is

1. A) open with blood “washing” through the coelomic cavity.
2. B) half closed with hearts pushing blood toward the head but washing posteriorly through an open cavity.
3. C) closed with dorsal and ventral blood vessels joined by five paired “hearts” forcing circulation flow dorsal-ventrally.
4. D) absent and they rely solely on diffusion to absorb gases through the epidermis.

5) Considering the age of the various segments of an annelid such as an earthworm,

1. A) they are born with all segments present and these merely grow in size; this allows segment count to be a major feature in their identification.
2. B) new segments are added just behind the prostomium, so the oldest segments are at the posterior end.
3. C) new segments are added just in front of the pygidium, so the oldest segments are at the anterior end.
4. D) segments grow and duplicate in a haphazard fashion preventing their use in identification.

6) The body wall of an annelid consists of

1. A) an epidermis and longitudinal muscles only, as is the case with nematodes.
2. B) a non-living cuticle, and inner circular muscles to squeeze the cuticle.
3. C) an epithelium that secretes cuticle, and layers of both longitudinal and circular muscles.
4. D) a bare epidermis with inner circular muscles and outer longitudinal muscles.
5. E) a soft exoskeleton to hold up in the absence of inner fluids, with outer circular muscles and inner longitudinal muscles.
