what is the diameter of earth in km UNANSWERABLE what is the axial tilt of the planet? Approximately 23.439281° describe the internal structure of it? It is divided into layers by their chemical or physical (rheological) properties. For eg. the outer layer is a chemically distinct silicate solid crust. what is a silicate? In chemistry, it is any member of a family of anions consisting of silicon and oxygen. how is it detected? It reacts with molybdate anions yielding yellow silicomolybdate complexes. what is zeolite to it? The nature of soluble silicates is relevant to understanding biomineralization and the synthesis of aluminosilicates, such as the industrially important catalysts called zeolites. is it naturally occurring? Conventional open-pit mining techniques are used to mine natural zeolites. what is "biomineralization"? It is the process by which living organisms produce minerals, often to harden or stiffen existing tissues. mention a few of its applications? Organic macromolecules collect and transport raw materials and assemble the substrates and into short- and long-range ordered composites with consistency and uniformity.

Biomineralization [SEP] Uranium contaminants in groundwater
Biomineralization may be used to remediate groundwater contaminated with uranium. The biomineralization of uranium primarily involves the precipitation of uranium phosphate minerals associated with the release of phosphate by microorganisms. Negatively charged ligands at the surface of the cells attract the positively charged uranyl ion (UO). If the concentrations of phosphate and UO are sufficiently high, minerals such as autunite (Ca(UO)(PO)•10-12HO) or polycrystalline HUOPO may form thus reducing the mobility of UO. Compared to the direct addition of inorganic phosphate to contaminated groundwater, biomineralization has the advantage that the ligands produced by microbes will target uranium compounds more specifically rather than react actively with all aqueous metals.
