A phenotype (from Greek phainein, meaning to show, and typos, meaning type) is the composite of an organism 's observable characteristics or traits, such as its morphology, development, biochemical or physiological properties, phenology, behavior, and products of behavior (such as a bird's nest).t may seem that anything dependent on the genotype is a phenotype, including molecules such as RNA and proteins. Most molecules and structures coded by the genetic material are not visible in the appearance of an organism, yet they are observable (for example by Western blotting) and are thus part of the phenotype.
In another process manganese dioxide is carbothermically reduced to manganese(II) oxide which is dissolved in sulfuric acid. The filtered solution is treated with ammonium carbonate to precipitate MnCO. 3. The carbonate is calcined in air to give a mixture of manganese(II) and manganese(IV) oxides. To complete the process, a suspension of this material in sulfuric acid is treated with sodium chlorate. Chloric acid, which forms in situ, converts any Mn(III) and Mn(II) oxides to the dioxide, releasing chlorine as a by-product. A third process involves manganese heptoxide and manganese monoxide.
Most of the common constituents of volcanic gases are hazardous to humans and other living forms in elevated concentrations. The main culprits causing deaths or health problems are carbon dioxide, sulfur dioxide, hydrogen sulfide, hydrochloric acid, hydrofluoric acid, and sulfuric acid.
