Q:The difference between the ignition of inorganic salts and organic matter
Inorganic salts that inorganic compounds in the salt, formerly known as minerals, the body has found more than 20 species, of which constant elements are iron, zinc, selenium, molybdenum, chromium, cobalt, iodine 8 species. If you pay attention to diet diversification, eat less animal fat, eat brown rice, corn and other coarse grains, do not eat too much refined flour, the body can make the inorganic salt to maintain the normal level.
Q:What is inorganic salt
The distribution of inorganic salts in the body is extremely uneven. For example, calcium and phosphorus are mostly in hard tissue such as bone and teeth, iron is concentrated in red blood cells, iodine is concentrated in the thyroid, barium is concentrated in adipose tissue, cobalt is concentrated in hematopoietic organs, and zinc is concentrated in muscle tissue.
Q:Common inorganic salt ions will appear when the corresponding symptoms
Zinc ion: growth and development, taste development disorders
Q:Does the inorganic salt fight the mass spectrum?
Can it be specific? What mass spectrometer, which inorganic salts. Do EI need samples can be vaporized, inorganic salts obviously not appropriate
Q:what is the function of salts in DNA extraction?
The role of the salt is to neutralize the charge of the DNA's sugar phosphate backbone. This makes the DNA less hydrophilic (less soluble in water). Ethanol has a lower dielectric constant than water so it's used to promote ionic bonds between the Na+ (from the salt) and the PO3- (from the DNA backbone) causing the DNA to precipitate, to extract DNA finally..
Q:Cells are composed of water and inorganic salts or by organic matter and none
There are also organic matter such as protein and lipid
Q:are acids, bases, salts and oxides belong to inorganic compound?
I think organic compunds are anything with Carbon(C), although I really don't know.
Q:would heterotrophic organism grow well in inorganic salt media? why or why not?
No. Heterotrophs get energy from the environment in the form of chemical bonds within organic molecules (such as glucose). An inorganic salt medium would not supply the needed organic molecules. Your heterotroph would starve.
Q:Inorganic salt of the inorganic salt function
Although inorganic salts in the cell content is relatively small, but there are many important role. Ca2 + is the animal bone and teeth (containing CaCO3) composition, and blood coagulation and muscle contraction has a regulatory role, if the content is too low, the animal will appear muscle twitch. K + is a variety of enzyme activator, for the plant starch and protein synthesis and animal nerve impulse conduction and muscle contraction also plays an important role. Fe is a component of hemoglobin and cytochrome, and iron-containing enzymes are indispensable when chlorophyll is formed in plants. Another example is Na + for animal heart beat, nerve excitement is indispensable. The various inorganic salts dissolved in the cells have a certain total concentration, such as human body fluid concentration of 0.9%, frogs of 0.65%, which for maintaining cell osmotic pressure, so that cells maintain a certain shape has an important role, too high or Too low will lead to cell due to water or dehydration to change the cell morphology. There are also a number of buffering systems in the body, which are a group which has a neutralizing effect on the added acid or base so that the pH does not change significantly and therefore plays an important role in maintaining the acid-base balance of the cells.
Q:How to get an inorganic salt
Inorganic salts are salts of inorganic compounds, formerly known as minerals. Plant growth needs N, P, K three elements and Ca, Zn, B, Mg, S, Fe and other trace elements. Depending on the type and amount of inorganic salts required for plant life, the water and various proportions of inorganic salts are scientifically formulated into plant nutrient solutions. The method of cultivating plants with plant nutrient solution is called soilless cultivation. The inorganic salts used to prepare the nutrient solution are generally not available for extraction, such as potassium nitrate, calcium nitrate, magnesium sulfate, potassium dihydrogen phosphate, copper sulfate, zinc sulfate and the like, and the reagent may be a chemical fertilizer. The purity of the reagent is high and the impurities of the fertilizer are more. If you can not get it, you can use soil leaching solution (fertile soil plus fresh water, the liquid obtained after filtration), which generally contains a variety of inorganic salts.
