GRADE.

3, how is the shipment time?

Within two weeks after confirmed the L/C or Deposit.

Q: I&#39;m said that with the increase of temperature the inorganic salts will decrease. Will that be correct?: IIRC, it depends on the salt.

Q: What is the physiological function of inorganic calcium: Maintain cell osmotic pressure and acid-base balance

Q: Are plants absorbing water and inorganic salts only through root tip or wrong? The: Plants through the leaves can also absorb water and inorganic salts, but the root tip is the main part of the plant to absorb water and inorganic salts.

Q: Organic chemistry extraction lab. If the KBr wasn&#39;t there I would just add HCl to protonate the NH2, but I&#39;m not sure if that will affect the KBr or the carbon chain. Both of these are in an aqueous phase.: The amine will certainly coordinate to K+, but the interaction is not very strong and hydrogen bonding from water will compete efficiently. Also, if your amine is soluble in water, you are not going to be able to isolate it by turning it into the corresponding ammonium salt.

Q: Octopus why the lack of boron-containing inorganic salts can cause rape to flow only without fruit: When the boron deficiency occurs, pollen tube germination is affected and poor fertilization leads to seed formation.

Q: What is inorganic salt? Lemon flavor, citric acid, is it an inorganic salt?: Although the inorganic salt in the cell, the body content is very low, but the effect is very large, if the attention of diet diversification, eat less animal fat, eat brown rice, corn and other coarse grains, do not eat too much refined flour, Salt to maintain the normal level of citric acid is an important organic acid, also known as citric acid, no ...

Q: Eat what food can add inorganic salt: Most of the food contains inorganic salts, the so-called inorganic salts, also known as minerals or ash. Minerals are naturally occurring compounds or natural elements in the crust. There are about 50 kinds of minerals in the human body, although they in the human body only 4% of body weight, but it is an essential part of the organism. According to their content in the body how much can be divided into constant elements and trace elements two categories. The body is actually composed of various elements (macro and trace). Many of these mineral elements are essential components of the enzyme, which can regulate a variety of physiological functions (such as maintaining osmotic pressure, oxygen transport, muscle contraction, nervous system integrity), but also tissue and bone growth and maintenance necessary. Some (such as calcium, phosphorus, sodium, magnesium, sulfur, chloride) content is large, while others are only trace. Human essential trace elements are cobalt (such as vitamin B12), copper, fluorine, iodine, iron, zinc, chromium, selenium, manganese, molybdenum In terms of its impact on experimental animals, nickel, tin and arsenic should also be considered necessary. Most minerals (except zinc) are widely distributed in a variety of foods and can be fully supplemented by balanced and diversified diets. However, there is a need for additional supplements to patients who have been relying on intravenous nutrition for long periods of time, infants and older persons, or because of the lack of regionalities caused by soil and water quality.

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: RO reverse osmosis water machine can remove impurities in the water, that the body will not be due to lack of minerals and malnutrition?: Modern people generally nutrient surplus, not because of the lack of minerals in the water and hurt, there is no such a report in medicine, Moreover, the world's drinking water into million, have been for decades, not because of water No minerals and malnutrition. The human body will not be due to trace minerals in the water and particularly strong, as long as the nutritional balance like the American Medical Journal (American Medical Journal) pointed out: the human body needs minerals from food, Not from drinking water.

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.
