Last Answer : Which one of the following is NOT a characteristic of phylum Annelida A. Closed circulatory ... Segmentation C. Pseudocoelom D. Ventral nerve cord
Description : Enlist the characteristic features of phylum Annelida.
Last Answer : Enlist the characteristic features of phylum Annelida.
Description : Into which classes is the phylum Annelida divided?
Last Answer : The phylum is divided into three classes: oligochaetes (for example, earthworms), hirudineans (e.g., leeches) and polychaetes (these are mostly marine aquatic with parapodia, like nereis). Image Diversity: oligochaetes polychaetes hirudineans
Description : Concerning the occurrence of separated sexes how are the beings of the phylum Annelida classified?
Last Answer : These beings may be dioecious (the majority of polychaetes) or hermaphrodite monoecious (oligochaetes and hirudineans).
Description : How is the nervous system characterized in beings of the phylum Annelida? How can one compare cephalization in annelids to cephalization in nematodes and platyhelminthes?
Last Answer : Annelids have a nervous system made of two ventral chords and one relatively big nervous cell concentration in its anterior portion resembling a primitive brain. Nematodes have an anterior neural ... is more outstanding than in nematodes or in flatworms. Image Diversity: earthworm nervous system

Description : How is the respiratory system of beings of the phylum Annelida characterized?
Last Answer : Respiration in annelids can be cutaneous or branchial. Cutaneous respiration occurs due to the rich vascularity under the epidermis. The gills, present in aquatic annelids, are located in the parapodia (false claws) that have an extensive capillary net. Image Diversity: annelid respiratory system

Description : What is the morphological characteristic that evolutionarily approximates the beings of the phylum Annelida to arthropods?
Last Answer : The metameric feature, i.e., the body segmentation in metameres, approximates annelids to arthropods since these animals are segmented beings too. (Bristles present in oligochaete and polychaete annelids are also covered with chitin, the same substance of the arthropod exoskeleton.)
Description : Which are the morphological features that differentiate the beings of the phylum Annelida from nematodes and platyhelminthes?
Last Answer : Platyhelminthes are worms with flat bodies (flatworms), nematodes are worms with cylindrical but not segmented bodies (roundworms). Annelids are cylindrical worms with segmented bodies (they are metameric).
