- Q: The stronger the transpiration is, the faster the absorption rate of inorganic salts and water is
- wrong. Can only promote the transport up! Can not promote absorption.
- 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: How much of the body's inorganic salts account for the weight of the body?
- The inorganic salts in the human body account for about 5%
- Q: What fruit contains more minerals?
- Persimmon contains a lot of carbohydrates, per 100 grams of persimmon containing 10.8 grams, mainly sucrose, glucose and fructose, which is why we feel very sweet persimmon persimmon in the other nutrients are not only contain a small amount of fat , Protein, calcium, phosphorus, iron and vitamin C. In addition, persimmon is rich in pectin, it is a water-soluble dietary fiber, a good laxative effect, for correcting constipation, to maintain normal intestinal flora Growth and so have a good effect.
- Q: What is the most important inorganic salt in plant growth?
- The inorganic salts required by plants are nitrogen, phosphorus and potassium containing inorganic salts, and if any lack of plants will affect the normal growth of plants, nitrogen is a component of many important organic compounds in the body, such as protein, nucleic acid, chlorophyll , Enzymes, vitamins, alkaloids and some hormones contain nitrogen. Nitrogen is also the basis of genetic material in all organisms, the most important protein, it is often in the center of metabolic activity.Now is to limit the growth of plants and the formation of the primary Factor. It also has a significant effect on improving the quality of the product.K2 is dissolved in the plant juice, and its main function is related to the metabolism of the plant.The content of phosphorus in the plant is second only to nitrogen and potassium, Phosphorus plays an important role in plant nutrition. Almost all important organic compounds in plants contain phosphorus. Phosphorus is involved in photosynthesis, respiration, energy storage and delivery, cell division, cell enlargement and other processes in plants.
- 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: Sodiumcorbonate is inorganic salt , why it is not organic substance even it contains carbon?
- Na2CO3 is joined by ionic bond not covalent C-C bond in organic molecules. @the other answerer: LOL! maybe i should expect a TD, too. Another problem with this section is students know how to ask but never know how to say thank you. Rarely do i see an asker selecting a BA. If i see one who does, whether i get the BA or not, i will definitely answer another question from that person.
- Q: By balancing the benefits of dietary supplementation with inorganic salts, what are the advantages and disadvantages of taking health care agents?
- Diet supplementation of inorganic salt or the nutritional needs of the human body is the normal diet of human absorption, rather than through deliberate conditioning to mobilize the body's ability to absorb (including deliberately balanced diet), that is, add inorganic salt only conventional diet Yes, no other adjustment supplement is its benefit, that is, healthy people do not need to like non-healthy state as a way to seek additional, this is his advantage.
- Q: What are minerals and trace elements?
- Trace elements refers to the body weight of one thousandth of the body weight, daily requirements are generally in the following 0.01 grams can meet the physiological needs of the human body, as we often talk about iron, zinc, iodine, selenium, fluoride and so on. Calcium in the human body due to more content, the daily requirements of several hundred milligrams, it is a macro element.
- Q: Does the plant absorb some of the inorganic salt?
- Of course, plant water absorption and absorption of inorganic salts are a certain association, inorganic salts to be dissolved in water to be absorbed, and inorganic salt ions in the transport of plants can not be separated from water.
