- Q: Children eat what to add the body of inorganic salts
- Such as fruits, vegetables, beans or soy products, kelp, eggs and so on. Eat hot and humid food: watermelon, bitter gourd, peach, ebony, strawberry, tomatoes, cucumber, mung bean and so on.
- Q: How does the edible base use?
- Alcohol is not a commonly used condiment, it is just a food loose agent and meat tenderener, can make dry goods raw materials quickly rise, soften the fiber, remove the dough's sour taste, the appropriate use can bring excellent food The color, smell, taste, shape, to enhance people's appetite. Alkaline used in a large number of food processing such as noodles, bread, bread and so on.
- Q: Please help i need the answer for a classwork assignment due today. I've looked everywhere online but i cant find the answer.
- the web page (below) discusses: Basal Salt Mixtures The use of balanced salt solution (BSS) in cell and tissue culture is generally attributed to early workers in the field. In 1885, Sydney Ringer developed a solution of inorganic salts designed to maintain contractility of mammalian heart tissue. A less specific salt solution was designed by Tyrode for use in work with primary mammalian cells. Tyrode's salt solution became the accepted fluid for diluting protein components of media of natural origin. Since that time, many other balanced salt solutions have been developed for use in cell and tissue culture. The current role of balanced salt solution in cell culture is multi-faceted and can be divided into four principle functions. see web page for extensive discussion on the good things about it
- Q: What is called alkali recovery
- Extraction equipment extraction status is good or bad, largely depends on the extraction of equipment. Different pulp, there are different equipment selection. At present the factory application is the most four series of drum-type vacuum washer. Its technology is mature, easy to operate, from the pulp into the pulp, the basic completion of the separation of pulp and black liquor, the extraction rate is also high. Pulp washing degree and the production of black liquor indicators are basically able to meet the choice of more manufacturers. The disadvantage is the big investment, power consumption.
- Q: How too much to eat too much inorganic salt
- Eat more inorganic salt, human body cells will be dehydrated, you will feel thirsty; if too much will be serious consequences, as if no one has done, after all, very difficult to eat.
- Q: General identification method of inorganic salts
- Take platinum wire, with hydrochloric acid wet, dipped in the test sample, burning in the colorless flame, the flame that was purple. But a small amount of sodium mixed, must be separated from the blue glass perspective can be identified. 2K ++ [PtCI6] 2- → K2PtCI6
- Q: what is the function of salts in DNA extraction?
- DNA can be purified for DNA sequencing or for restriction digestion by precipitation in an alcohol/water mixture in the presence of a high concentration of inorganic salt. DNA is recovered from the aqueous solution by addition of salt to final concentrations of 0.8M LiCl, 0.3-0.5M NaCl, NaOAc, or 2.5M NH4Ac and an appropriate volume of alcohol (30%-50% final percentage isopropanol; 60%-80% final percentage ethanol), storage for a brief period of time at -20°C or -70°C, followed by centrifugation. Subsequent desalting of the DNA pellet involves rinsing in 70% alcohol, recentrifugation and re-suspension in appropriate buffer.
- Q: Is urea an inorganic salt?
- Is not organic matter ah inorganic salts are present in the body and food minerals in the mineral, composed of organic matter and inorganic synthesis of the human body has been found to have more than 20 kinds of essential inorganic salts, about 4 to 5% of body weight. More (> 5g) for calcium, phosphorus, potassium, sodium, chlorine, magnesium, sulfur seven; daily dietary requirements are more than 100mg, known as constant elements. Other low content, with the modern analysis of technological progress Iron, copper, zinc, manganese, cobalt, molybdenum, selenium, chromium, nickel, silicon, fluorine, vanadium and other elements were found by atomic absorption spectroscopy, neutron activation, plasma emission spectroscopy and other trace analysis methods. But also the human body is necessary, the daily dietary requirements for the amount of μg ~ mg called trace elements.
- Q: What is the use of inorganic salts in plants? How is it discharged
- Not just light plants, for the body, the inorganic salts are essential. Can provide the necessary elements, including a large number of elements C, H, O, N, S, P, K, Ca, Mg. Trace elements Fe, Mn, B, Zn, Cu, Mo, Cl, Ni, etc. For plants, inorganic salts are also essential. The inorganic salts provide C, H, O are the essential elements of the constituents of the carbohydrate, N is the essential element that constitutes the protein, P is the essential element that constitutes ATP and DNA, and so on, including trace elements such as: B, Will cause the plants to flow only without fruit. These elements may be provided in the form of inorganic salts. So inorganic salts are necessary for plants. On the issue of discharge. Plants will use these elements, C, H, O synthetic carbohydrates, in the role of respiration when the decomposition of carbon dioxide and water to the nature of the. Plants also store oil and fat, protein, such as peanut oil and protein content is high. In general, the plant is the inorganic salt into organic matter and stored, through the decomposition of part of the organic matter to breathe in the form of other inorganic substances. Apoptosis is also the way in which the inorganic salts it absorbs are discharged in the form of organic matter. In general, the inorganic salts absorbed by the plant are discharged in the form of other inorganic substances (respiration) or in the form of organic matter (apoptosis). Plants will use these inorganic salts.
- Q: The power of the water and inorganic salts in the plant is derived from the action of the plant
- The transpiration of plants in the body of water in the form of water vapor into the atmosphere when it is a "pump" principle, it provides a vertical pull for the root of the water, while dissolved in the water in the same salt Is absorbed and transported upward, the power is derived from the transpiration of plants
