In earthworms, inability to produce offspring might be associated with:a) lack of a true coelomb) the inability of a worm to fertilize its own eggsc) a malfunction of the nephridiad) a malfunction of the clitellum

slide11

Most Flatworms are small and very thin. Therefore, they can supply their cells with oxygen and remove metabolic wastes by means of:a) simple diffusion between body surface and the environmentb) an open circulatory system without a heartc) an open circulatory system with one heartd) a closed circulatory system with one heart

in annelids nitrogen containing wastes are eliminated by a clitella b parapodia c nephridia d gills
In annelids, nitrogen-containing wastes are eliminated by:a) clitellab) parapodiac) nephridiad) gills
slide15

One way to distinguish a roundworm from an annelid is to:a) count their germ layersb) examine their body symmetryc) compare the structure of their body cavitiesd) determine whether they have cephalization

slide50

Two echinoderms that are in the same class area) brittle stars and sea starsb) sea stars and sea cucmbersc) sea cucumbers and sea urchinsd) sea urchins and sand dollars

slide52

The plates of the endoskeleton are reduced and contained inside a soft, muscular body wall ina) sand dollarsb) sea cucumbersc) sea urchinsd) brittle stars

slide54

The water-vascular system of echinoderms is involved with each of the following body functions EXCEPTa) respirationb) circulationc) movementd) reproduction

slide56

slide63

Cephaliziation refers to the a) division of the body into upper and lower sidesb) concentration of sense organs and nerve cells in the front of the bodyc) joining together of specialized cells to form tissuesd) formation of a body cavity

slide67

The blastula is a stage of development of an embryo that consists ofa) a solid ball of cellsb) a hollow ball of cellsc) a flat sheet of cellsd) a folded sheet of cells
