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



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
