Q:Why vegetables and fruits contain rich inorganic salts
Because they are plants! From the biological point of view, they are the nature of the organic matter into inorganic salt carrier
Q:What is the most important inorganic salt in plant growth?
The inorganic salts required by plants are nitrogen, phosphorus and potassium containing inorganic salts, and if any lack of plants will affect the normal growth of plants, nitrogen is a component of many important organic compounds in the body, such as protein, nucleic acid, chlorophyll , Enzymes, vitamins, alkaloids and some hormones contain nitrogen. Nitrogen is also the basis of genetic material in all organisms, the most important protein, it is often in the center of metabolic activity.Now is to limit the growth of plants and the formation of the primary Factor. It also has a significant effect on improving the quality of the product.K2 is dissolved in the plant juice, and its main function is related to the metabolism of the plant.The content of phosphorus in the plant is second only to nitrogen and potassium, Phosphorus plays an important role in plant nutrition. Almost all important organic compounds in plants contain phosphorus. Phosphorus is involved in photosynthesis, respiration, energy storage and delivery, cell division, cell enlargement and other processes in plants.
Q:Effect of Inorganic Salts on Viscosity
possible. The inorganic salt is dissolved in water to form positive and negative ions, and the ions of the micelles are extruded to make the solubility smaller and form an increase in the viscosity. With the increase in the amount of inorganic salt, it does not have the ability to dissolve in water, there is no micelles and the molecular state exists in the water, the liquid becomes thin ...
Q:What foods contain zinc-containing inorganic salts
1st: oysters (71.2 / 100g / 100g)
Q:The stronger the transpiration is, the faster the absorption rate of inorganic salts and water is
Due to dry conditions are not complete, the lack of text, can not be a normal answer.
Q:are there any other foods than water and salt that have an abiotic origin (lifeless, inorganic)?
Various minerals we need, like iron, zinc, magnesium, etc. That's it. These also are not technically foods, as the first poster said.
Q:Which crop feet can provide C N inorganic salts for fungal growth
Plant growth requires a variety of inorganic salts, which require the most is nitrogen, phosphorus, potassium containing inorganic salts. If a lack of some inorganic salts, plants can not grow normally. Kind of crops need fertilization, farm manure contains organic matter, the microbial decomposition of the soil will produce a large number of inorganic salts for plant growth and utilization, the role of fertilizer is to provide a variety of plant growth of inorganic salts. Therefore, in agricultural production, the application of fertilizer and farm manure is intended to provide a variety of inorganic salts for crops.
Q:After running the training is best to drink what drinks add inorganic salt
C100 ah
Q:My inorganic diet seems to be working but I am getting tired of the taste of rock salt. Should I continue?
Its all a matter of self-preservation.
Q:People lack the inorganic salt will be what disease
Calcium deficiency can lead to osteomalacia, osteoporosis, etc., can also lead to convulsions.
