It occurs mixed with stearin and olein in the fat of animal tissues, with olein and butyrin in butter, with olein in olive oil, etc. Chemically, it is a glyceride of palmitic acid, three molecules of palmitic acid being united to In all the genera of this group the uterus is double, and the true vagina is separated, either wholly or for a considerable extent, into two lateral canals. Both the digestive and generative tubes terminate within a common cloacal outlet, and the term Monotremata,therefore, though confined to the Edentate Marsupiata,is so far applicable to the whole of this aberrant division. deer n (animal of the family Cervidae):: ciervu m, venáu m deer n (meat from the animal) SEE: venison:: deer meat n (venison) SEE: venison:: defeat v (to overcome in battle or contest):: vencer: defeat n (to be checked and sorted: the act of defeating or being defeated):: vencimientu m defy n (challenge) SEE: challenge:: At the time of telophase, small membraneous vesicles filled with polysaccharides, formed in the golgi complex, form on the metaphaste plate. The vesicles continue to form to form until they are more or less continuous and forms a double membrane, which is called the cell plate. The cell plate becomes impregnated with pectin and forms a cell wall. Published 2003 Grolier, Danbury, CT 06816. A. Division of Scholastic Library Publishing.

Animals are all heterotrophs (they obtain their energy from organic substances produced other organisms); they have eukaryotic cells (the genetic material is contained within a distinct nucleus) bounded a thin cell In all cases, when the air of the atmosphere, or that which the water contains, is impregnated with noxious particles, many individuals of a particular species, living in the same district, suffer at the same time.

In the marsupial animals, which, from a structural peculiarity, produce their young in a far more immature state than any other mammals, the period of gestation is very short, being thirty-nine days in the kangaroo, the largest of the marsupial animals, and
