molecule: An electrically impartial group of atoms that represents the smallest doable quantity of a chemical compound. Molecules may be fabricated from single kinds of atoms or of various varieties. For instance, the oxygen within the air is fabricated from two oxygen atoms (O₂), however water is fabricated from two hydrogen atoms and one oxygen atom (H₂O).

monoterpene: A sort of molecule with 10 carbon atoms and 16 hydrogen atoms that usually produces a scent.

native: Related to a specific location; native vegetation and animals have been present in a specific 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 have been planted or moved there by individuals). Most are notably properly tailored to their atmosphere.

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 3 oxygen atoms. The time period can also be used as a common identify for any of varied associated compounds shaped by the mixture of such atoms.

nitrogen dioxide: A gasoline ­— typically abbreviated as NO2 — that has change into an vital pollutant in city air. Most of this gasoline within the Earth’s decrease ambiance has been launched by human actions. Gasoline- and diesel-fueled automobiles are among the many most typical sources of NO2 in cities. Coal- and natural-gas-burning energy vegetation can also emit regionally excessive quantities. This pollutant may cause respiration issues and worsen lung-related ailments comparable 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 type when fossil fuels are burned. The scientific image for these chemical compounds 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 components of flowers that may fertilize the feminine tissue to make a seed. Pollinating bugs, comparable to bees, typically choose up pollen that may later be eaten.

pollinator: One thing that carries pollen, a plant’s male reproductive cells, to the feminine components of a flower, permitting fertilization. Many pollinators are bugs comparable to bees.

pollutant: A substance that taints one thing — such because the air, water, our our bodies or merchandise. Some pollution are chemical compounds, comparable to pesticides. Others could also be radiation, together with extra warmth or mild. Even weeds and different invasive species may be thought-about a kind 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, generally known as a response, that results in new chemical compounds or modifications in present chemical compounds.

species: A bunch of comparable organisms able to producing offspring that may survive and reproduce.

delicate: Adjective for one thing which may be vital, however may be laborious 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 laborious to differentiate from close by wholesome tissues.

upwind: A designation for the route from which winds are blowing.

wind tunnel: A facility used to review the results of air shifting previous strong objects, which frequently are scale fashions of real-size objects comparable to airplanes and rockets. The objects usually are coated with sensors that measure aerodynamic forces like raise and drag. Additionally, generally engineers inject tiny streams of smoke into the wind tunnel in order that airflow previous the article is made seen.
