molecule: An electrically impartial group of atoms that represents the smallest attainable quantity of a chemical compound. Molecules will be product of single varieties of atoms or of various sorts. For instance, the oxygen within the air is product of two oxygen atoms (O2), however water is product of two hydrogen atoms and one oxygen atom (H2O).
monoterpene: A kind of molecule with 10 carbon atoms and 16 hydrogen atoms that usually produces a scent.
native: Related to a selected location; native vegetation and animals have been present in a selected location since recorded historical past started. These species additionally are likely to have developed inside a area, occurring there naturally (not as a result of they had been planted or moved there by individuals). Most are significantly effectively tailored to their setting.
nectar: A sugary fluid secreted by vegetation, particularly by flowers. It encourages pollination by bugs and different animals. It’s collected by bees to make into honey.
nitrate: An ion shaped by the mixture of a nitrogen atom certain to a few oxygen atoms. The time period can be used as a common title for any of varied associated compounds shaped by the mixture of such atoms.
nitrogen dioxide: A gasoline — usually abbreviated as NO2 — that has grow to be an necessary pollutant in city air. Most of this gasoline within the Earth’s decrease environment has been launched by human actions. Gasoline- and diesel-fueled autos are among the many commonest sources of NO2 in cities. Coal- and natural-gas-burning energy vegetation can also emit regionally excessive quantities. This pollutant could cause respiration issues and irritate lung-related ailments corresponding to bronchial asthma. Nitrogen dioxide is among the many pollution that contribute to the formation of smog and acid rain.
nitrogen oxides: Pollution made up of nitrogen and oxygen that kind when fossil fuels are burned. The scientific image for these chemical substances is NOx (pronounced “knocks”). The precept ones are nitric oxide (NO) and nitrous oxide (NO 2 ).
particle: A minute quantity of one thing.
pollen: Powdery grains launched by the male elements of flowers that may fertilize the feminine tissue to make a seed. Pollinating bugs, corresponding to bees, usually choose up pollen that can later be eaten.
pollinator: One thing that carries pollen, a plant’s male reproductive cells, to the feminine elements of a flower, permitting fertilization. Many pollinators are bugs corresponding to bees.
pollutant: A substance that taints one thing — such because the air, water, our our bodies or merchandise. Some pollution are chemical substances, corresponding to pesticides. Others could also be radiation, together with extra warmth or gentle. Even weeds and different invasive species will be thought-about a sort of organic air pollution.
radical: (in chemistry) A molecule having a number of unpaired outer electrons. Radicals readily participate in chemical reactions. The physique is able to making radicals as one means to kill cells, and thereby rid itself of broken cells or infectious microbes.
reactive: (in chemistry) The tendency of a substance to participate in a chemical course of, often known as a response, that results in new chemical substances or modifications in current chemical substances.
species: A bunch of comparable organisms able to producing offspring that may survive and reproduce.
refined: Adjective for one thing which may be necessary, however will be onerous to see or describe. As an illustration, the primary mobile modifications that sign the beginning of a most cancers could also be solely subtly totally different — as in small and onerous to tell apart from close by wholesome tissues.
upwind: A designation for the route from which winds are blowing.
wind tunnel: A facility used to review the consequences of air transferring previous stable objects, which frequently are scale fashions of real-size gadgets corresponding to airplanes and rockets. The objects usually are lined with sensors that measure aerodynamic forces like raise and drag. Additionally, typically engineers inject tiny streams of smoke into the wind tunnel in order that airflow previous the item is made seen.
