micro organism: (adj: bacterial) Single-celled organisms. These dwell almost in all places on Earth, from the underside of the ocean to inside different dwelling organisms (equivalent to crops and animals). Micro organism are one of many three domains of life on Earth.
biologist: A scientist concerned within the research of dwelling issues.
cell: (in biology) The smallest structural and purposeful unit of an organism. Sometimes too small to see with the unaided eye, it consists of a watery fluid surrounded by a membrane or wall. Relying on their dimension, animals are made from anyplace from 1000’s to trillions of cells. Most organisms, equivalent to yeasts, molds, micro organism and a few algae, are composed of just one cell.
atmosphere: The sum of the entire issues that exist round some organism or the method and the situation these issues create. Setting might discuss with the climate and ecosystem by which some animal lives, or, maybe, the temperature and humidity (and even the placement of issues within the neighborhood of an merchandise of curiosity).
fiber: One thing whose form resembles a thread or filament. (in diet) Elements of many fibrous plant-based meals. These so-called non-digestible fibers have a tendency to come back from cellulose, lignin, and pectin — all plant constituents that resist breakdown by the physique’s digestive enzymes.
focus: (in physics) The purpose at which rays (of sunshine or warmth for instance) converge typically with the help of a lens. (In imaginative and prescient, verb, “to focus”) The motion an individual’s eyes take to adapt to mild and distance, enabling them to see objects clearly.
gene: (adj. genetic) A phase of DNA that codes, or holds directions, for a cell’s manufacturing of a protein. Offspring inherit genes from their mother and father. Genes affect how an organism seems to be and behaves.
glass: A tough, brittle substance created from silica, a mineral present in sand. Glass often is clear and pretty inert (chemically nonreactive). Aquatic organisms known as diatoms construct their shells of it.
lens: (in biology) A clear a part of the attention behind the coloured iris that focuses incoming mild onto the light-absorbing membrane in the back of the eyeball. (in physics) A clear materials that may both focus or unfold out parallel rays of sunshine as they move via it. (in optics) A curved piece of clear materials (equivalent to glass) that bends incoming mild in such a manner as to focus it at a specific level in house. Or one thing, equivalent to gravity, that may mimic a number of the mild bending attributes of a bodily lens. (in social points) An angle or perspective that helps carry broad points into focus.
microbe: Quick for microorganism. A dwelling factor that’s too small to see with the unaided eye, together with micro organism, some fungi and lots of different organisms equivalent to amoebas. Most include a single cell.
molecule: An electrically impartial group of atoms that represents the smallest attainable quantity of a chemical compound. Molecules will be made from single sorts of atoms or of various sorts. For instance, the oxygen within the air is made from two oxygen atoms (O2), however water is made from two hydrogen atoms and one oxygen atom (H2O).
monitor: To check, pattern or watch one thing, particularly on an everyday or ongoing foundation.
optical fiber: A protracted strand of glass or another fiber used to transmit mild indicators (equivalent to these used to ship phone, tv and different communications indicators).
particle: A minute quantity of one thing.
plastic: Any of a collection of supplies which can be simply deformable; or artificial supplies which have been created from polymers (lengthy strings of some building-block molecule) that are usually light-weight, cheap and proof against degradation. (adj.) A fabric that is ready to adapt by altering form or presumably even altering its operate.
Proceedings of the Nationwide Academy of Sciences: A prestigious journal publishing authentic scientific analysis, begun in 1914. The journal’s content material spans the organic, bodily and social sciences. Every of the greater than 3,000 papers it publishes annually, now, are usually not solely peer reviewed but in addition accredited by a member of the U.S. Nationwide Academy of Sciences.
protein: A compound created from a number of lengthy chains of amino acids. Proteins are a vital a part of all dwelling organisms. They kind the idea of dwelling cells, muscle and tissues; additionally they do the work within cells. Antibodies, hemoglobin and enzymes are all examples of proteins. Medicines continuously work by latching onto proteins.
vary: The total extent or distribution of one thing. As an illustration, a plant or animal’s vary is the world over which it naturally exists. (in math or for measurements) The extent to which values can range (equivalent to the very best to lowest temperatures). Additionally, the gap inside which one thing will be reached or perceived.
decision: (in optics) A time period having to do with the diploma of readability or element with which some object will be seen. (v. resolve)
sea: An ocean (or area that’s a part of an ocean). In contrast to lakes and streams, seawater — or ocean water — is salty.
seawater: The salty water present in oceans.
sponge: One thing that sops up liquids or different supplies and holds them till squeezed out or eliminated in another manner. (in biology) A primitive aquatic animal with a gentle, porous physique.
artificial: An adjective that describes one thing that didn’t come up naturally, however was as a substitute created by individuals. Many artificial supplies have been developed to face in for pure supplies, equivalent to artificial rubber, artificial diamond or an artificial hormone. Some might also have a chemical make-up and construction an identical to the unique.
