- Q:what is the function of the organic part of bone matrix?of the inorganic part(bone salts)?
- The organic part is where blood cells are manufactured. The inorganic part is for structural strength
- Q:TRUE OR FALSE: the addition of salts to water will always increase the surface tension of water. explain.?
- False. Although inorganic salts will increase surface tension of the water by increasing the attractive forces between water molecules on the surface, organic salts will typically (always?) decrease the surface tension.
- Q:Why does inorganic salts affect chemical degradation of organic wastewater
- Industrial organic waste water is highly toxic and stable pollutants, for such waste water is difficult to use conventional physical, chemical and biological methods. This paper summarizes the main processing technologies of biodegradable organic wastewater at home and abroad, including biological treatment, chemical treatment and physical treatment and various joint treatment processes. The methods or processes of various methods or processes are described.
- 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:What are the effects of inorganic salts on plant growth?
- P: to promote the development of seedlings and flowers open, so that the fruit, the seeds mature early. Lack of performance: the plant is particularly short, leaves were green, and purple.
- Q:Does the inorganic salt affect the gpc molecular weight results?
- GPC determination of molecular weight through the column when the molecular size of the molecular peak, the molecular weight of the early comparison of the peak, that is relatively large molecules in the GPC pillars can not pass, pass the molecules were detected out of the peak, This molecular weight is not absolute, since the GPC determination is actually the size of the molecule rather than the size of the molecule, and of course it is also possible to approximate the molecular weight of the molecular weight of the molecule. Large; exactly how their relationship, with GPC can not be determined, only through the standard liquid molecular weight to compare, this result is relative, not absolute.
- Q:How to extract inorganic salts in soil?
- Find a piece of mud, with water, filter out the permeate, filter with filter paper. The liquid was placed in a beaker and dried to obtain white crystals
- 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:Determination of the existence of inorganic salts in the soil, in the filter, should pay attention to the matter
- Two low: filter edge is lower than the edge of the funnel;
- Q:What is the time when the maximum number of inorganic salts is needed
- Potassium is ion-soluble in plant juice, and its main function is related to the metabolism of plants.
