Q:What is the alkaline powder? Baking soda? Sodium carbonate or something else?

Baking soda is very easy to absorb the air of the air, so when not in use when the best way to retract, such as sealed cans or folder chain or milk powder cans. Use, you can use a commercially available pepper to retract, but not Add the lid, pepper cans of the hole is very easy to sprinkle the small soda.There is no pepper cans, you can also have a hole in the cloth, such as not the yarn quality curtains, mosquito nets, etc., tied tied to the general bottle, It is easy to pour out to use.If you just want a simple moisture and deodorant, you can put the small soda in the old cotton socks, and then sealed with a rope, and then any use can be

Q:During the different periods of plant growth, the amount of water and inorganic salt required is different.

Plant life, although the need for a variety of inorganic salts, but different plants on the various types of inorganic salt requirements are different, such as cabbage, spinach and other human needs leaves of vegetables need nitrogen containing inorganic salts, tomato, peanuts need phosphorus Of the inorganic salt and more, sweet potatoes, potatoes need potassium-containing inorganic salts; the same plant with the growth period of the different requirements of inorganic salts are not the same, for example, plants in the seedling period requires nitrogenous inorganic salts , In the flowering, the results of the period of time need more phosphorus-containing inorganic salts. Therefore, different plants and the same plant growth period, the need for inorganic salts are different. So the answer is: different; different

Q:what is the function of salts in DNA extraction?

DNA can be purified for DNA sequencing or for restriction digestion by precipitation in an alcohol/water mixture in the presence of a high concentration of inorganic salt. DNA is recovered from the aqueous solution by addition of salt to final concentrations of 0.8M LiCl, 0.3-0.5M NaCl, NaOAc, or 2.5M NH4Ac and an appropriate volume of alcohol (30%-50% final percentage isopropanol; 60%-80% final percentage ethanol), storage for a brief period of time at -20°C or -70°C, followed by centrifugation. Subsequent desalting of the DNA pellet involves rinsing in 70% alcohol, recentrifugation and re-suspension in appropriate buffer.

Q:is table salt organic or inorganic, why?

if its found in nature its organic if its made by man its synthetic. table salt is found in the ocean so i guess it would be organic.

Q:What is the risk of low inorganic salt?

Phosphorus into the body of phosphorus containing 750-800mg about 1% of body weight, mineral weight of 1/4. Of which 87.6% in the form of hydroxyapatite bone salt stored in the bones and teeth, 10% with protein, fat, sugar and other organic matter combined constitute soft tissue, the rest distributed in the muscle, skin, nerve tissue and other tissues and membranes Of the ingredients. Function Phosphorus is present in every cell of the human body, which is indispensable for bone growth, tooth development, renal function and nerve conduction. Phosphorus is a component of nucleic acids, phospholipids and certain enzymes, which promotes growth and tissue repair. It helps carbohydrate fat and protein utilization, regulates glycogen breakdown, and participates in energy metabolism. Phospholipids are the major components of the cell membrane, which are related to the permeability of the membrane. Phosphate can regulate the metabolism of vitamin D, to maintain the stability of calcium within the environment. Lack of disease  phosphorus deficiency when the mental confusion, cranial nerve palsy, transport disorders, muscle weakness, hypothyroidism, anorexia, joint stiffness, abnormal blood, urinary calcium increased. Typical cases  hyperphosphatemia, renal dysfunction, or hypoparathyroidism and hypothyroidism and other endocrine diseases can also occur. Too many symptoms  nerve excitement, tetany and convulsions. The physiological requirement of phosphorus is 12.3mg / kg / d. Calcium / phosphorus ratio in the 2: 1-1: 2 appropriate range. Food sources  food in the meat, fish, milk, beans and hard shells and other phosphorus more.
