Naphtha polloi]." It enters the word napalm, a contraction of the "na" of "naphthenic acid" and "palm" of "palmitic acid", originally made from a mixture of naphthenic acid combined with aluminium and magnesium salts of palmitic acid. Naphtha is the root of the word naphthalene, and can also be recognised in the word phthalate, and the paint colour phthalo blue. In older usage, "naphtha" simply meant crude oil, but this usage is now obsolete in English. It was also used for mineral spirits (also known as "Stoddard Solvent"), originally the main active ingredient in Fels Naptha laundry soap. The Ukrainian and
Evidence of common descent sequence homology (amino acid for amino acid), as do pigs, cows and sheep. Both humans and chimpanzees share the identical molecule, while rhesus monkeys share all but one of the amino acids: the 66th amino acid is isoleucine in the former and threonine in the latter. What makes these homologous similarities particularly suggestive of common ancestry in the case of cytochrome c, in addition to the fact that the phylogenies derived from them match other phylogenies very well, is the high degree of functional redundancy of the cytochrome c molecule. The different existing configurations of amino acids do not significantly
