Q: Why plasma osmotic pressure and protein, inorganic salt content: The crystal osmotic pressure is determined by the content of inorganic salts; colloid osmotic pressure is mainly determined by the protein content, especially albumin.

Q: Why inorganic salt waterproof coating does not apply to roof waterproofing: Inorganic salts are generally in the form of waterproof agent, generally mixed with cement quality of 3-5 percent, Jiangxi Nanchang rhyme waterproof material factory

Q: Does the plant absorb some of the inorganic salt?: Plants absorb moisture and absorb inorganic salts are two relatively independent processes.

Q: Why does inorganic salts affect chemical degradation of organic wastewater: Industrial organic waste water is highly toxic and stable pollutants, for such waste water is difficult to use conventional physical, chemical and biological methods. This paper summarizes the main processing technologies of biodegradable organic wastewater at home and abroad, including biological treatment, chemical treatment and physical treatment and various joint treatment processes. The methods or processes of various methods or processes are described.

Q: Cells are composed of water and inorganic salts or by organic matter and none: There are, but the water accounted for most of the inorganic salt to maintain cell acid and alkali balance;

Q: A. oxygen demanding wastesB. organic plant nutrientsC. inorganic plant nutrientsD. water soluble inorganic chemicalsE. sediment: Acids, D. water soluble inorganic chemicals salts, D. water soluble inorganic chemicals metals E. sediment

Q: What is the risk of low inorganic salt?: Phosphorus into the body of phosphorus containing 750-800mg about 1% of body weight, mineral weight of 1/4. Of which 87.6% in the form of hydroxyapatite bone salt stored in the bones and teeth, 10% with protein, fat, sugar and other organic matter combined constitute soft tissue, the rest distributed in the muscle, skin, nerve tissue and other tissues and membranes Of the ingredients. Function Phosphorus is present in every cell of the human body, which is indispensable for bone growth, tooth development, renal function and nerve conduction. Phosphorus is a component of nucleic acids, phospholipids and certain enzymes, which promotes growth and tissue repair. It helps carbohydrate fat and protein utilization, regulates glycogen breakdown, and participates in energy metabolism. Phospholipids are the major components of the cell membrane, which are related to the permeability of the membrane. Phosphate can regulate the metabolism of vitamin D, to maintain the stability of calcium within the environment. Lack of disease  phosphorus deficiency when the mental confusion, cranial nerve palsy, transport disorders, muscle weakness, hypothyroidism, anorexia, joint stiffness, abnormal blood, urinary calcium increased. Typical cases  hyperphosphatemia, renal dysfunction, or hypoparathyroidism and hypothyroidism and other endocrine diseases can also occur. Too many symptoms  nerve excitement, tetany and convulsions. The physiological requirement of phosphorus is 12.3mg / kg / d. Calcium / phosphorus ratio in the 2: 1-1: 2 appropriate range. Food sources  food in the meat, fish, milk, beans and hard shells and other phosphorus more.

Q: Calcium is not an inorganic salt: No, inorganic salts are compounds, calcium is simple. But the body of inorganic salts in the calcium content accounted for a larger proportion.
