These carbohydrate products are then variously used to form other organic compounds, such as the building material cellulose, as precursors for lipid and amino acid biosynthesis or as a fuel in cellular respiration. Pangaea (pan- jee -uh) The supercontinent formed near the end of the Paleozoic era when plate movements brought all the land masses of Earth together. paraphyletic ( par -uh- fy -leh-tik) Pertaining to a taxon that excludes some members that share a common ancestor with members included in the taxon. Peristalsis Gk. peristellein, to wrap around Rhythmic waves of contraction of smooth muscle that push food along the digestive tract. peritoneum Gk. peritonos, stretched over A membrane that lines the body cavity and forms the external covering of the visceral organs. The cyanobacteria contain chlorophyll and oxygen, in the same way that chloroplasts do, in fact chloroplasts are now considered to have evolved from cyanobacteria by endosymbiosis. The other photosynthetic bacteria have a variety of different pigments, called bacteriochlorophylls, and do not produce oxygen.
Peridotite Coarse grained ultramafic igneous rock composed mainly of olivine and pyroxene. The mantle is though to be composed primarily of this rock type. Periglacial Landforms created by processes associated with intense freeze-thaw action in an area high latitude areas or near an alpine or continental glacier.
Pedogenic Regime The particular soil forming process that operates in a certain climate. Some of the main processes are: laterization, salinization, podzolization, calcification, and gleization. Pedogenesis Process of soil formation. Pedology The scientific study of soils. For example, a change from solid to liquid to a gas. Phloem Food conducting tissue in vascular plants. Photochemical Smog Photochemical smog is a condition that develops when primary pollutants (oxides of nitrogen and volatile organic compounds created from fossil fuel combustion) interact under the influence of sunlight to produce a mixture of hundreds of different. Others go on to regenerate RuBP so the process can continue (see Calvin Cycle). The 'Z-scheme' of electron flow in light-dependent reactions Discovery Although some of the steps in photosynthesis are still not completely understood, the overall photosynthetic equation has been known since the 1800s. Feeding causes the host to be less fit and may eventually cause premature death. Parasitism Biological interaction between species where a parasite species feeds on a host species. Parent Material The mineral material from which a soil forms. Peptide bond Gk. pepto, to soften, digest The covalent bond between two amino acid units, formed by condensation synthesis. peptidoglycan ( pep -tid-oh- gly -kan) A type of polymer in bacterial cell walls consisting of modified sugars cross-linked by short polypeptides. Carbon Fixation The fixation of carbon dioxide is a light-independent process in which carbon dioxide combines with a five-carbon sugar, ribulose bisphosphate (RuBP to give two molecules of a three-carbon compound, glycerate 3-phosphate (GP). BACK pacemaker A specialized region of the right atrium of the mammalian heart that sets the rate of contraction; also called the sinoatrial (SA) node. See Sinoatrial node. paedogenesis (pee-doh- jen -eh-sis) The precocious development of sexual maturity in a larva. Found in arid locations and normally covered by fluvial deposits. Pediplain An arid landscape of little relief that is occasionally interrupted by the presence of scattered inselbergs. Formed by the coalescence of several pediments. Peridotite Coarse grained ultramafic igneous rock composed mainly of olivine and pyroxene. The mantle is though to be composed primarily of this rock type. Periglacial Landforms created by processes associated with intense freeze-thaw action in an area high latitude areas or near an alpine or continental glacier. To learn more, visit the. Matthew Shepard Foundation» Learn more from ADL: Curriculum Connections on LGBT Inclusion». Today it's run by Hunter Wendelstedt, who assumed control after his father's death in 2012. The cost for the five-week professional course is 2,350 and includes tuition, hotel room, rulebook, course materials and uniform: a T-shirt and a cap. Racial Profiling Thesis Statement The public contracts to become to a greater extent aware of the harm caused by racial profiling, and demand that polices. Poor Claudels downfall is swift and lonely by comparison, whilst Rodins star continues in the ascendant. She destroyed most of her works whilst he, after a brief lull following his death, continues to this day to be one of the most widely recognised loved sculptors. Async (of course). In your own script you should use var async require async to include it. Express. js is used as an http server. db is a fictionary database module. Jan van Helmont began the research of the process in the mid-1600s when he carefully measured the mass of the soil used by a plant and the mass of the plant as it grew.
Permeable L. permeare, to pass through Penetrable by molecules, ions, or atoms; usually applied to membranes that let given solutes pass through. peroxisome (per- oks -eh-some) A microbody containing enzymes that transfer hydrogen from various substrates to oxygen, producing and then degrading hydrogen peroxide.
