| 66675221 | Animals | are multicellular heterotrophs organsims that lack cell walls. | 0 | |
| 66675222 | vertebrates | animals that have back bone | 1 | |
| 66675223 | invertebrates | do not have a backbone | 2 | |
| 66675224 | specialization | is the evolutionary adaptation of cell for a particular function | 3 | |
| 66675225 | ingestion | an animal takes in organic material or food, usually in the form of other living things | 4 | |
| 66675226 | zygote | the diploid cell that results from the fusion of the gametes,then undergoes repeated mitotic divisions | 5 | |
| 66675227 | differentiation | cells become specialized and therefore different from each other | 6 | |
| 66675228 | chordate | refers to animals with a notochard | 7 | |
| 66675229 | notochard | a firm, flexible rod of tissue located in the dorsal part of the body | 8 | |
| 66675230 | dorsal nerve cord | is a hollow tube above the notochord | 9 | |
| 66675231 | pharyngeal pouches | are small putpockets of the anterior digestive tract. | 10 | |
| 66675232 | symmetry | is a body arrangement in which parts that lie on opposite sides of an axis are identical. | 11 | |
| 66675233 | radial symmetry | a body plan in which the parts are organized in a cirlce around an axis | 12 | |
| 66675234 | dorsal | animals that have ( back) | 13 | |
| 66675235 | ventral | animals that have (abodomen side) | 14 | |
| 66675236 | anterior | towards to the head | 15 | |
| 66675237 | posterior | toward to the tail | 16 | |
| 66675238 | bilaterial symmetry | such animals have to similiar halves on either side of a central plane displays | 17 | |
| 66675239 | cephalization | the concentration of sensory and brain structure in the anterior end of the animal. | 18 | |
| 66675240 | germ layers | are tissues layers in the embryos of all animals except sponges, which have no true tissues. | 19 | |
| 66675241 | segemntation | in animals refers to a body composed of a series of repeating similiar units. | 20 | |
| 66675242 | exoskeleton | is a rigid outer covering that protects the soft tissues of many animals, including arthropods, such as crustaceans, which includes crayfish. | 21 | |
| 66675243 | gills | organs that consists of blood vessels surrounded by a membrane and are specialized for gas exchange in the water. | 22 | |
| 66675244 | open circulatory system | in which cirulcatory fluid is pumped by the heart through vessels and into the body cavity and is then returned to the vessels. | 23 | |
| 66675245 | closed circulatory system | blood is pumped by a heart and circulates through the body in vessels that form a closed loop. | 24 | |
| 66675246 | hermaphrodite | is an organsim that produces both male and female gametes, allowing a single individual to function as both a male and female. | 25 | |
| 66675247 | larva | is a free-living, immature form of an organsim that is a morphologically different from the adult. | 26 | |
| 66675248 | vertebrae | the repeating bony units of the backbone | 27 | |
| 66675249 | endoskeleton | an internal skeleton made of bone and cartilage, which includes the backbone | 28 | |
| 66675250 | integument | the outer coverint of an animal | 29 | |
| 66675251 | kidneys | filters wastes from the blood while regulating water levels in the body. | 30 | |
| 66676576 | Lungs | are organs for gas exhange composed of moist, membranous surface deep inside the animal's body | 31 | |
| 67753712 | fertilization | is the union of female and male gametes to form a zygote | 32 | |
| 67753713 | cleavage | the series of cell division that occurs immediately following fertilization is termed | 33 | |
| 67753714 | blastula | as the number of dividing cells further increases, the mass becomes hollow ball of cells | 34 | |
| 67753715 | gastrulation | reorganization of the cells of the hollow blastula begins with the inward movement of cells at one end of the blastula | 35 | |
| 67753716 | gastrula | transforms the blastula into a multilayered embryo | 36 | |
| 67753717 | archenteron | as the inward folding continues the now cup- shaped embryo enlarges, and a deep cavity, or primitive gut, develops | 37 | |
| 67753718 | blastopore | the open end of the archenteron | 38 | |
| 67753719 | ectoderm | forming the outer layer of the gastrula is the outer germ layer | 39 | |
| 67753720 | endoderm | the inner germ layer | 40 | |
| 67753721 | mesoderm | forms between the endoderm and the ectoderm | 41 | |
| 67753722 | pseudocoelom | a cavity that is not completely lined by mesoderm | 42 | |
| 67753723 | coelom | a cavity completely lined by mesoderm | 43 | |
| 67753724 | protostomes | in the embryos of mollusks, arthropods, and annelids, the blastopore develops into a mouth, and a second opening forms at the other end of the archenteron, forming an anus...protostomes also means "first mouth" | 44 | |
| 67753725 | deuterostomes | in the embryos of echinoderms and chordates, the blastopore develops into an anus, and a second opening at the other end of the archenteron becomes the mouth...it's also called "second mouth" | 45 | |
| 67753726 | schizocoely | the mesoderm then spreads and splits to form the coleom | 46 | |
| 67753727 | enterocoely | the coelom develops within the mesodermal pouches | 47 | |
| 67753728 | acoelomates | animals, such as flatworms, that do not have a body cavity | 48 |
