As long as the meat will stay good for, you can leave it marinading in the fridge. I standaâ¦rdly marinade for 1 night but if i bought a lot of tips and don't wanna cook them all, ill keep them soaking for a few days. The last ones i cook are usually the best. 6 people found this useful.
The genetic mechanism behind human skin color is mainly regulated by the enzyme tyrosinase, which creates the color of the skin, eyes, and hair shades. Differences in skin color are also attributed to differences in size and distribution of melanosomes in the skin. Melanocytes produce two types of melanin.
Skin color is due primarily to the presence of a pigment called melanin, which is controlled by at least 6 genes. Both light and dark complexioned people have melanin. However, two forms are produced--pheomelanin, which is red to yellow in color, and eumelanin, which is dark brown to black.n lighter skin, color is also affected by red cells in blood flowing close to the skin. To a lesser extent, the color is affected by the presence of fat under the skin and carotene, a reddish-orange pigment in the skin. Hair color is also due to the presence of melanin.
