Question:I need help with my Biology project, I need to do a side show wiith information pretaining to the Phylum Chordata, but the info is either to vague or just not there. Thanks for the help I really apprieciate it.

Answers:Class Agnatha: (Lamprey and Hagfish) General Characteristics: Absence of jaws. These organisms lack the paired fins (pelvic and pectoral). Skeleton made of cartilage. Round eel-like body with a compressed caudal fin. Soft skin devoid of scales. They lack a swim bladder and gill covers (operculum). 7 gill slits on each side of the head. The lamprey are parasitic and the hagfish are scavengers. Ectothermic (animals that cannot control their body temperature). External fertilization. Oviparous (egg laying) Marine and fresh water species are found. Lateral line Two chambered heart Gills used for respiration No external ears No eye lids

Question:I have a project for school that my group has the Animalia Kingdom for and since our class is pretty big, we have the vertebrate half of the Animalia Kingdom and another group has the invertebrate half. My marine biology teacher is insisting that there are at least 5 phyla that make up the vertebrate part of the kingdom, but I can only find the chordata phylum. Does anyone know of another phylum that makes up vertebrates?

Answers:There's the one Phylum - Chordata - notochord present at some time disappearing early in many forms, either temporary or permanent paired gill slits; dorsal nerve cord. The Vertebrates are one of four subphylums under Chordata. There are seven Classes that make up the vertebrate part of the subphylum Cyclostomata ( example: lamprey eel - no true jaws, scales or fins) Chondrichthyes (Examples-sharks, rays) Osteichthyes ( bony fishes ) Amphibia Reptilia Aves Mammalia

Question:I need information on the phylums... Porifera Cnidaria Platyhelminthes nematoda mollusca annelida arthropoda echinodermata chorodata the meaning of the name, atleast two classes from that phylum, 3 common examples of species from that phylum, major living environments, economic importance of that phylum, unique characteristics ie: reproductive method, body parts, type pf symmetry. please dont give me a web site!!!!!!!!! best answer will be rewarded so try hard!

Answers:1. The correct word is "phyla," not "phylums." 2. You need to do your own homework. I would be happy to help with specific questions, but not an entire homework assignment.

Question:6 Kingdoms:(Animalia, Plantae, Fungi, Protista, Archaea, and Eubacteria)

Answers:Animalia:phylum porifera,cnideria,platyhelminthes,nematoda,annelida, and mollusca examples: hookworms,tapeworms, planarians,liver fluke,earthworms. Plantae:phylum bryophyta,hepaticophyta,anthcerophyta,lycophyta,and arthrophyta examples:club moss, quillwort,Boston fern, tree fern Fungi:phylum, zygomycota,ascomycota,basidiomycota and deuteromycota examples: penicillium,shelf fungi, puffballs, and mushrooms. Protista: Phylum Ciliophora,zoomastigina,sporozoa,sarcodina, and chrysophyta, also, chlorophyta and phaeophyta ( there are ALOT) Examples:Navicula,amoeba,paramecium Archaea:(sorry don't know this one) Examples: methanogens,thermoacidophilic bacteria, and salt-loving bacteria Eubacteria: (sorry don't know this one either) examples: blue-green bacteria,chemoautotrophs,prochlorobacteria, rickettsiae ------------------------------ Hope I helped a bit :D
