5.FAQ

1)Q:Are you a factory or trading company?

A:We are a factory.

2)Q:What is thepayment terms?

A: L/C ,T/T, D/P, W/U

3)Q:How can I get some samples?

A: Kindly send us your address, we are honored to offer you samples.

4)Q:How does your factory do regarding quality control?

A: Our factory can accept any third party inspection.

Q:Would the amount of saltwater drops a penny surface could hold without spilling increase, or decrease, as the salt concentration increases? Also, maybe an explanation behind why it increases/decreases?Thank you!: The source below says inorganic salts increase surface tension. In the present case increasing the concentration of salt (and so increasing the surface tension) would result in an increase in the number of drops being held on the surface of the penny.

Q:The effect of inorganic salt medium and the difference with enrichment medium: The enrichment of nutrients is based on the basis of nutrition based on some kind of nutrient-rich substances for the target cells, the purpose is to increase the number of target cells, so that the formation of growth advantages, so as to achieve the purpose of separation, such as we have to be separated Pseudomonas aeruginosa, this bacteria particularly like blood, so you can add blood in the medium, so that the formation of growth advantages of this bacteria.

Q:A. food gathering and digestion B. photosynthesis and diatom structures C. reproduction and osmosis D. wave and current motions: its not a so try b or c those 2 are the most likely to be the right answers

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:Do inorganic mercury salts bioaccumulate?: Yes they do bioaccumulate. Mercury builds up for years and years, and eventually sits in a residue of pure mercury. - JJ

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: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.

Q:Why is the residue after burning known as coarse ash? And inorganic salt content What is the difference: GB / T5009.4-2003 "Determination of ash in food" (a) the principle of a certain amount of samples after carbonization into the high temperature furnace burning, the organic matter is oxidized decomposition to carbon dioxide, nitrogen oxides and Water and other forms of escape, and inorganic substances to sulfate, phosphate, carbonate, chloride and other inorganic salts and metal oxide in the form of residual

Q:Is it possible to adjust the internal temperature of the carbohydrate in the vacuole: multi-cell plant cells are living in the individual within the water environment, but this environment with the human body's internal environment can only be similar is not the same, and plant cells and no extracellular liquid this argument.

Q:Several inorganic salts are lacking in symptoms and food sources: Ingredients of zinc-containing inorganic salts (trace): animal liver (viscera), fruit, peanuts, etc.
