cell: (in biology) The smallest structural and practical 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 manufactured from anyplace from 1000’s to trillions of cells.
chemical: A substance shaped from two or extra atoms that unite (bond) in a set proportion and construction. For instance, water is a chemical made when two hydrogen atoms bond to 1 oxygen atom. Its chemical formulation is H2O. Chemical additionally could be an adjective to explain properties of supplies which might be the results of numerous reactions between totally different compounds.
chemical response: A course of that includes the rearrangement of the molecules or construction of a substance, versus a change in bodily type (as from a strong to a fuel).
chemistry: The sphere of science that offers with the composition, construction and properties of gear and the way they work together. Scientists use this data to review unfamiliar substances, to breed giant portions of helpful substances or to design and create new and helpful substances.
colleague: Somebody who works with one other; a co-worker or staff member.
compound: (usually used as a synonym for chemical) A compound is a substance shaped when two or extra chemical components unite (bond) in fastened proportions. For instance, water is a compound manufactured from two hydrogen atoms bonded to 1 oxygen atom. Its chemical image is H2O.
copper: A metallic chemical aspect in the identical household as silver and gold. As a result of it’s a good conductor of electrical energy, it’s extensively utilized in digital gadgets.
darkish matter: Bodily objects or particles that emit no detectable radiation of their very own. They’re believed to exist due to unexplained gravitational forces that they seem to exert on different, seen astronomical objects.
develop: To emerge or to make come into being, both naturally or by human intervention, corresponding to by manufacturing.
DNA: (quick for deoxyribonucleic acid) An extended, double-stranded and spiral-shaped molecule inside most dwelling cells that carries genetic directions. It’s constructed on a spine of phosphorus, oxygen, and carbon atoms. In all dwelling issues, from vegetation and animals to microbes, these directions inform cells which molecules to make.
discipline: An space of examine, as in: Her discipline of analysis is biology. Additionally a time period to explain a real-world atmosphere wherein some analysis is carried out, corresponding to at sea, in a forest, on a mountaintop or on a metropolis avenue. It’s the reverse of a synthetic setting, corresponding to a analysis laboratory.
immune system: The gathering of cells and their responses that assist the physique combat off infections and cope with overseas substances that will provoke allergic reactions.
innovation: (v. to innovate; adj. revolutionary) An adaptation or enchancment to an present concept, course of or product that’s new, intelligent, simpler or extra sensible.
metallic: One thing that conducts electrical energy properly, tends to be shiny (reflective) and is malleable (which means it may be reshaped with warmth and never an excessive amount of pressure or stress).
microscope: An instrument used to view objects, like micro organism, or the only cells of vegetation or animals, which might be too small to be seen to the unaided eye.
molecule: An electrically impartial group of atoms that represents the smallest doable quantity of a chemical compound. Molecules could be manufactured from single kinds of atoms or of various sorts. For instance, the oxygen within the air is manufactured from two oxygen atoms (O2), however water is manufactured from two hydrogen atoms and one oxygen atom (H2O).
neuroscientist: Somebody who research the construction or perform of the mind and different elements of the nervous system.
Nobel prize: A prestigious award named after Alfred Nobel. Finest often known as the inventor of dynamite, Nobel was a rich man when he died on December 10, 1896. In his will, Nobel left a lot of his fortune to create prizes to those that have performed their greatest for humanity within the fields of physics, chemistry, physiology or drugs, literature and peace. Winners obtain a medal and enormous money award.
organism: Any dwelling factor, from elephants and vegetation to micro organism and different kinds of single-celled life.
polymer: A substance constructed from lengthy chains of repeating teams of atoms. Manufactured polymers embrace nylon, polyvinyl chloride (higher often known as PVC) and lots of kinds of plastics. Pure polymers embrace rubber, silk and cellulose (present in vegetation and used to make paper, for instance).
protein: A compound constructed from a number of lengthy chains of amino acids. Proteins are an important a part of all dwelling organisms. They type the idea of dwelling cells, muscle and tissues; additionally they do the work within cells. Among the many better-known, stand-alone proteins are the hemoglobin (in blood) and the antibodies (additionally in blood) that try to combat infections. Medicines incessantly work by latching onto proteins.
recall: To recollect.
RNA: A molecule that helps “learn” the genetic info contained in DNA. A cell’s molecular equipment reads DNA to create RNA, after which reads RNA to create proteins.
T cells: A household of white blood cells, often known as lymphocytes, which might be major actors within the immune system. They combat illness and may help the physique cope with dangerous substances.
tumor: A mass of cells characterised by atypical and sometimes uncontrolled progress. Benign tumors is not going to unfold; they only develop and trigger issues in the event that they press in opposition to or tighten round wholesome tissue. Malignant tumors will finally shed cells that may seed the physique with new tumors. Malignant tumors are often known as cancers.
