Q:The power of the water and inorganic salts in the plant is derived from the action of the plant
The main process is: soil moisture → root hair → root catheter → stem catheter → leaf catheter → stomata → atmosphere.
Q:how come inorganic salts increase surface tension of water?
Surface Tension Of Salt Water
Q:Where are the parts of the bryophyte absorb water and inorganic salts?
Moss moss moss, moss Gang, moss root through the fake root absorption, that is, the use of cell penetration technology, moss Gang has evolved out of the root, so you can directly through the relatively low roots to absorb Oh
Q:What foods contain zinc-containing inorganic salts
2nd place: pecan (cooked) [walnut] (12.59 / 30g / 100g)
Q:Inorganic salts in solution?
Mn or Zn. Both MnSO4 and ZnSO4 solutions are water-white. KMnO4 is purple. But you did not stipulate.
Q:What are minerals and trace elements?
Trace elements, although not much in the human body, but closely related to human survival and health. Their intake of excessive, inadequate, or lack of will cause varying degrees of human physiological abnormalities or disease. The most prominent role of trace elements is closely related to the vitality of life, just like the size of the matchhead or less the amount can play a huge physiological role. It is worth noting that these trace elements must be supplied directly or indirectly from the soil. According to scientific research, so far, due to the use of pesticide overdose, resulting in a large number of trace elements loss, so we have to indirectly add trace elements, the use of mineral power to supplement the lack of trace elements in the human body. There are 18 kinds of essential trace elements related to the detection of human health and life, namely iron, copper, zinc, cobalt, manganese, chromium, selenium, iodine, nickel, fluorine, molybdenum, vanadium, tin, silicon, strontium, Rubidium, arsenic and so on. Each of these trace elements has its own special physiological function. Although they are extremely small in the human body, they are necessary to maintain some of the decisive metabolism in the human body. Once the lack of these essential minerals trace elements, the body will be disease, and even life-threatening. Such as zinc deficiency can cause mouth, eyes, anus or genital redness, pimples, rash. Another example is iron is one of the main components of hemoglobin, iron deficiency can cause iron deficiency anemia. Abroad has been reported: the body of iron, copper, zinc reduction, can weaken the immune mechanism (resistance to disease), reduce disease resistance, contribute to bacterial infection, and infection after the mortality rate is also higher. Trace elements in disease resistance, anti-cancer, longevity and other aspects also play a role can not be ignored.
Q:Cells are composed of water and inorganic salts or by organic matter and none
There are also organic matter such as protein and lipid
Q:My inorganic diet seems to be working but I am getting tired of the taste of rock salt. Should I continue?
Stay on your diet, you salty dog you.
Q:is table salt organic or inorganic, why?
Inorganic - NaCl - no complex carbon compounds.
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.
