Most of these elements come from minerals in a process called mineral nutrition.

Most gemstones are hard, but some soft minerals are used in jewelry because of their luster or other physical properties that have aesthetic value.

Most of natron's uses both in the home and by industry were gradually replaced with closely related sodium compounds and minerals.

Most forest soils in Southeastern region are deficient in N and P as well as trace minerals.

Most species also require this water to be pure, as nutrients, salts, or minerals in their soil can stunt their growth or even kill them.

Most minerals that enter into the dietary physiology of organisms consist of simple compounds of chemical elements.

Most land plants and thus, one might say, the very existence of land ecosystems rely on mutualisms between the plants which fix carbon from the air, and Mycorrhyzal fungi which help in extracting minerals from the ground.

Most of the soil is loose, well-aerated, and rich in minerals and organic matters that enable full development of the root systems.

Most of the sinking mafic minerals form ultramafic cumulates which stay at the base of the crust.

Most volcanic rocks share a number of common minerals.

Most mining and minerals processing wastes contain minerals, such as sulphides, which are formed at higher temperatures and pressures at geological depth.

Most commonly cracks and fissures opened by tectonic activity ( folding and faulting ) are partially filled by quartz, calcite, and other secondary minerals.

Most known to the public for its Great Hall of Dinosaurs, which includes a mounted juvenile Apatosaurus and the long mural, The Age of Reptiles ; it also has permanent exhibits dedicated to human and mammal evolution ; wildlife dioramas, Egyptian artifacts ; and the birds, minerals and Native Americans of Connecticut.

Most carbonatites tend to include some silicate mineral fraction ; by definition an igneous rock containing > 50 % carbonate minerals is classified as a carbonatite.

Most of the time it is found in nature combined with other metals and minerals that contain silver compounds, generally in the form of sulfides such as galena ( lead sulfide ) or cerussite ( lead carbonate ).

Most sedimentary rocks incorporate tiny amounts of iron rich minerals, whose orientation is influenced by the ambient magnetic field at the time at which they formed.

Most macroscopic inorganic solids are polycrystalline, including almost all metals, ceramics, ice, rocks, etc.

Most of their animation films feature puppets made of doll parts and other organic and inorganic materials, often partially disassembled, in a dark, moody atmosphere.

" Most autotrophs capture the suns energy in chlorophyll, but some autotrophs ( the chemolithotrophs ) obtain energy by the chemical oxidation of inorganic compounds and can grow in dark environments, such as the sulfur bacterium Thiobacillus, which lives in hot sulfur springs.

Most inorganic and organic azides are prepared directly or indirectly from sodium azide.

Most grave goods recovered by archaeologists consist of inorganic objects such as pottery and stone and metal tools but there is evidence that organic objects that have since decayed were also placed in ancient tombs.

Most sulfate-reducing bacteria can also reduce other oxidized inorganic sulfur compounds, such as sulfite, thiosulfate, or elemental sulfur ( which is reduced to sulfide as hydrogen sulfide ).

Most oculocutaenous albinistic humans appear white or very pale as the melanin pigments responsible for brown, black, and some yellow colorations are not present.

Most artists today use modern synthetic pigments, which are less toxic but have similar color properties to the older pigments.

Most pigments used in manufacturing and the visual arts are dry colorants, usually ground into a fine powder.

Most pigments are charge-transfer complexes, like transition metal compounds, with broad absorption bands that subtract most of the colors of the incident white light.

Most of the pigments in use were earth and mineral pigments, or pigments of biological origin.

Most of cadmium produced worldwide is used in the production of nickel-cadmium batteries, but about half the remaining consumption, which is about 2, 000 tons annually, is used to produce colored cadmium pigments.

Most grey pigments have a cool or warm cast to them, as the human eye can detect even a minute amount of saturation.

Most grappa is clear, indicating it is an unaged distillate, though some may retain very faint pigments from their original fruit pomace.

Most nail polishes are made of nitrocellulose dissolved in a solvent ( e. g. butyl acetate or ethyl acetate ) and either left clear or colored with various pigments.

Most of the light is absorbed by melanin pigments in the pigment epithelium just behind the photoreceptors, and causes burns in the retina.

Most colored textile and leather articles are treated with azo dyes and pigments.

Most paints labeled " Naples yellow " are instead made with a mix of modern, less toxic pigments.

Most of the above-described syntheses have application in the synthesis of porphyrins, bile pigments, and dipyrrins.
