Q:the absorption of inorganic salts is how to absorb the form
Root cell cell concentration is high, with the external soil moisture to form osmotic pressure, resulting in water and dissolved in water in the inorganic salt flow to the root cells, the absorption method is in the form of dissolved, so it is in the form of ions. If the salt can not be dissolved can not be absorbed, as for the specific water and inorganic salt transport can refer to 2017.7.25 know the daily newspaper.
Q:What is the relationship between inorganic salts and minerals?
Generally speaking, inorganic salts, including minerals, inorganic salts are not minerals. Some inorganic salts can be soluble in water and some can not, the vast majority of minerals do not dissolve in water, otherwise the rain on the rocks are not dissolved Is it gone?
Q:What are the effects of water, inorganic salts, carbohydrates, proteins, fats and vitamins?
The main physiological function of fat: 1. The supply of human heat. (Per gram of fat oxidation can produce 9 kcal of calories, protein and carbohydrates produce more than 2 times.) 2. constitute the body's adipose tissue, adjustable body temperature, To prevent the body outside the scattered, to protect the internal organs, moisturizing the skin. 3. Dissolve nutrients. (Some do not dissolve in water and only soluble in lipids, only in the presence of fat can be absorbed by the body.
Q:What do we get from the milk?
Incense is not it Well! After your girlfriend will be like the 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: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.
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:Of the dissolved salts found in seawater, _____ % are minor inorganic salts, or trace. ?
it's definitly one of these: 99.28 .72 72 50 i think it's 99.28. lemme no if you get it right!!
Q:Is the inorganic salt related to the excitement
Should be excited about conduction and inorganic salts. Membrane on both sides of the solution is conductive, in the excitement of the nerve segment and adjacent it is not between the excitement, due to the existence of potential difference in the charge movement, which is the local current. Its flow direction is: there is a positive charge outside the membrane has never excited to flow to the excitement section, the cell has a positive charge from the excited flow to the excitement section, the current direction is not excited to fiber membrane depolarization. When this current is strong enough to depolarize the segment to reach the threshold, a new nerve impulse - action potential is generated.
Q:Where can I find a list of all inorganic salts?
That list is near endless. There are countless inorganic cations and organic groups that can combine with these ions. Pretty much every metallic element in the periodic table will form cations with bromide and chloride. Not sure about phosphate, but most metals will bind with it. Carbonate will be trickier, as some ions are too acidic and will decompose the carbonate (iron(III) is an example, and it will form the oxide instead, liberating CO2 in the process). Aside from simple elemental ions, there are also polyatomic cations (such as ammonium) and lots of complexes that will form compounds with these anions.
