Q:What is the difference between inorganic and inorganic salts?
Organic matter: generally used in the biological field, especially in the agricultural sector, narrowly refers to all can be biological (including microbial and plant enzymes) decomposition of organic matter.
Q:Can inorganic salts be tested by LC / MS?
LC-MS mass spectrometer for organic matter, inorganic salts can not be atomized not applicable, and will pollute the instrument.
Q:What are the nutritional requirements for bacterial growth?
For carbon: pathogens are mainly obtained from sugars.
Q:How to extract inorganic salts in soil?
Dissolve, filter, evaporate
Q:People lack the inorganic salt will be what disease
severe phosphorus deficiency can lead to anorexia, anemia and so on.
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: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 salts play an important role in maintaining the life activities of living organisms. It is mainly in the form of living organisms.
Inorganic salts are mineral nutrients present in the body and in the food. Most inorganic salts in the cells are present in the form of ions, consisting of organic matter and inorganic compounds.
