Q: Can you please help me with this question and give me a website reference.: Many of these materials enter the water through natural channels---minerals, salts and the like come from exposure to rocks, dirt and other inorganic materials.

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: How to isolate the effects of inorganic salts on enzyme solubility: The raw materials of cotton stalk were pretreated with inorganic salt to dissolve part of lignin and hemicellulose, so as to improve the enzymatic hydrolysis efficiency. Sulfuric acid, sulfuric acid and sulfuric acid were used to pretreat the cotton stalk. The solid solution was separated and the lignin removal rate and the elution rate of the pentosan were determined. The solid phase was hydrolyzed at 50 ℃. Enzyme hydrolysis conversion rate; the process of glucose, pentosan, lignin for material accounting.

Q: What are minerals and trace elements?: 81 species were detected on the basis of the human body. 81 kinds of elements in the body of the arrangement is very tight combination, and more less will not work. Human anatomy found that there are 74 kinds of serum, 54 kinds of brain, 49 kinds of heart, 50 kinds of liver, thymus 18 species. They constitute the most basic unit of the human body, human life, old, sick, dead and all elements related to the body. According to the elements in the human body content is different, can be divided into macro elements and trace elements two categories. Accounting for more than 0.01% of the total body weight of the elements, such as carbon, hydrogen, oxygen, nitrogen, calcium, phosphorus, magnesium, sodium, etc., called macro elements; , Zinc, copper, manganese, chromium, selenium, molybdenum, cobalt, fluorine, etc., known as trace elements. Trace elements in the human body content is really minimal, such as zinc only the total weight of the human body of thirty-three parts per million. Iron is only sixty thousandths.

Q: In order to prove that magnesium is an essential salt for soybean life, two soybean seedlings with the same growth status are taken, one of them is cultured in magnesium-containing culture medium and the other is cultured in (). A. Pure water B. Sand without sand. Water containing only magnesium. Media containing no magnesium: Biological control experiments were the only variable experiments. The question that is being explored is the variable, and the other quantities are the same. In a different amount (conditions) the same circumstances to modify a data variable in order to get the data variables on the experimental changes in the law. In order to prove that magnesium is essential for the life of soybeans, the variable is the presence or absence of magnesium. Can be designed as a magnesium-containing culture medium and magnesium-free culture medium. The other amount of the same as the amount of culture medium, soybean seedling growth status, the same number, while placed in the same place, etc., to ensure that only one variable that is the presence of magnesium.

Q: Does the plant roots absorb inorganic salt ions must be active: Plants absorb inorganic salts and do not necessarily absorb water. Plants absorb moisture and absorb inorganic salts are two relatively independent processes. Plants absorb moisture through the infiltration of root cells to absorb water, the process is essentially free of water diffusion process, neither the carrier nor the need for energy; and plant absorption of inorganic salts is carried out by means of active transport, This process requires the carrier and consumes the energy generated by cell metabolism. Of course, plant water absorption and absorption of inorganic salts are a certain association, inorganic salts to be dissolved in water to be absorbed, and inorganic salt ions in the transport of plants can not be separated from water.

Q: What are the main physiological functions of inorganic salts?: o maintain the body acid and alkali balance and osmotic pressur

Q: in the ocean: Salts are the result of the association of cations and anions. Cations are usually metals like Calcium, Sodium, Potassium anions are ususally sulfates, phosphates, carbonates...... calcium carbonate and calcium phosphate are useful in making bone. Potassium Chloride is important in heart beat regulation Sodium Chloride is important in maintaining blood pressure. Carbonate is important in blood chemistry and the transfer of energy within a cell. all these salts are found in abundance in the ocean. If you follow evolution, those salts in the ocean have given rise to our own blood chemistry and organic health.

Q: RO reverse osmosis water machine can remove impurities in the water, that the body will not be due to lack of minerals and malnutrition?: Early society has not yet entered the era of industrial development, then the life of drinking tap water pollution, but also relatively clean, in the case of completely pollution-free, of course, stored in the water only a trace of beneficial minerals on the human body, through our daily life But now the industrial development, destruction of our water, we can not for the slightest beneficial to the human body of minerals, and to absorb a lot of harmful substances in the body it! Moreover, the minerals in the water and the water in the water, Is not the main source of human needs, we can get from the daily diet of the human body needs 99.9% of the minerals, water contains organic matter, inorganic matter is not necessarily absorbed by the human body, or even harmful is not necessarily.

Q: Would the amount of saltwater drops a penny surface could hold without spilling increase, or decrease, as the salt concentration increases? Also, maybe an explanation behind why it increases/decreases?Thank you!: The source below says inorganic salts increase surface tension. In the present case increasing the concentration of salt (and so increasing the surface tension) would result in an increase in the number of drops being held on the surface of the penny.
