- Q: The effect of inorganic salt medium and the difference with enrichment medium
- The landlord said the basic nutrient base? That is based on the inorganic salt with carbon source and energy sources, such as beef extract, peptone, etc., the basic nutrients can provide the necessary cells to grow cells.
- Q: Where are the parts of the bryophyte absorb water and inorganic salts?
- Moss moss moss, moss Gang, moss root through the fake root absorption, that is, the use of cell penetration technology, moss Gang has evolved out of the root, so you can directly through the relatively low roots to absorb Oh
- 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: What do we get from the milk?
- Milk is rich in minerals, calcium, phosphorus, iron, zinc, copper, manganese, molybdenum. The most rare is that milk is the best source of calcium in the human body, and the proportion of calcium and phosphorus is very appropriate, conducive to the absorption of calcium. Species is complex, at least 100 kinds, the main ingredients are water, fat, phospholipids, protein, lactose, inorganic salts
- Q: An inorganic salt is dissolved in water and yields a solution that has a color. Make a statement about the type of element the substance contains that casuses the color.Thanks!
- Many inorganic salts form colored solutions . pper ( II) sulfate ( Blue ) nickel (II) acetate = green, mangaanse ( II) chloride = pink, iron(III) chloride = yellow, potassium dichromate, orange and so many more Can you be more specific ?
- Q: What is the difference between "organic salt" and "inorganic salt"? What is the difference between "organic salt" and "inorganic salt"?
- Inorganic salts are inorganic acids (hydrochloric acid, sulfuric acid, nitric acid) with alkali generated by the reaction of the salt is called inorganic salts. Inorganic salts are salts that do not contain carbon, and organic salts are carbon-containing but do not include carbonates.
- Q: Effects of Minerals on Plants
- Minerals have a significant effect on plants, plants require about 25 elements, CHONPS Na Mg AL B MO Ca Fe Zn, etc. Most of these minerals have these elements, which are absorbed in the soil by roots and transported to plants Different parts, the role of a lot of plants lack of mineral leaves will be yellow, such as if there is no Mg, it can not be normal photosynthesis, because Mg is the necessary elements of synthetic chlorophyll, etc., if you want to know more profound, you can put each Kind of elements are checked.
- Q: What are the nutritional requirements for bacterial growth?
- The nutritional conditions required for bacterial growth generally include water, carbon, nitrogen, inorganic and growth factors
- 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: I am 18 years old, test the body of inorganic salt content of 3KG, people say that low. What is the value of this use? How can improve it?
- Inorganic salts are inorganic compounds in the salt, formerly known as minerals, the body has found more than 20 species, including constant elements of iron, zinc, selenium, molybdenum, chromium, cobalt, iodine 8. If you pay attention to diet diversification, eat Animal fat, eat brown rice, corn and other coarse grains, do not eat too much refined flour, can make the body of inorganic salt to maintain the normal level should be.
