Olaplex can be used as a stand-alone treatment to re-boot heat-damaged and coloured hair like mine, but it can also be used as part of the colouring process, which is its real selling point. The three-step programme works by repairing bonds within the hair shaft, known as disulphide bonds.
Nitrogen combines with other molecules in the body to produce toxic compounds such as ammonia. And so the animal must find a way to excrete these toxins. As we already know, this is the function of the kidneys and the rest of the renal system.Ammonia has only one nitrogen per molecule, but it is quite toxic.ammals metabolize ammonia into a molecule called urea: As you can see, this molecule contains two atoms of nitrogen. Although it requires metabolic energy to build, it also is less toxic than ammonia, and it requires less water to flush from the system.
* are responsible for the excretion of carbon dioxide and water (waste products of cellular respiration) * these are removed as gases during the process of exhalation. B) Liver. * recycles worn out red blood cells * produces urea (a semi-toxic nitrogenous waste) from the breakdown of amino acids (contains nitrogen). water (98%), salts, and a small amount of urea diffuse from the blood into sweat glands * excreted through the process of perspiration (sweating!) * main job of sweating is to maintain body temperature (cool down). * site of most urea excretion * controls the concentration of most of the body fluids.
