Without changing the size of the shot glass, however, the amount of alcohol in a shot can go as high as 95%, or 2.85 standard drinks. This means, for instance, that if you have one shot of 190-proof Everclear, you have consumed 2.85 times as much alcohol as you would if you had one shot of 72-proof whisky.
Pigments that contribute to skin color are called carotene, a yellowish hemoglobin, in blood vessels (pink-red), and melanin (black, brown, red). Darker skins are dominated by melanin, which is produced from the amino acid tyrosine, by pigment cells (melanocytes) in the skin.igments that contribute to skin color are called carotene, a yellowish hemoglobin, in blood vessels (pink-red), and melanin (black, brown, red).

Melanin is brown.. the more Melanin, the darker the skin, eyes, or hair. Dark brown eyes may appear to be black, but they are not, they are brown. Also the brown hair and eyes are believed to be originated from Asia, as Asia is where the oldest human ancestor has been found (it was originally thought to be Africa)..not in Europe.rown hair and eyes and olive-white skin tones were the first mutation to the white race. Africans â¦ and Asians have naturally black hair, black-colored eyes (no visible brown at all) and very dark or black skin tones.
