Q:Are plants absorbing water and inorganic salts only through root tip or wrong?
Plants through the leaves can also absorb water and inorganic salts, but the root tip is the main part of the plant to absorb water and inorganic salts.
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:Why are inorganic sodium salts much better soluble in ethanol than potassium salts?
The reason seems to be : - Ionization potential of pottasium is lower than that of sodium ,thereore potassium salts are more polar as compared to sodium salts; - Potassium being more reactive than the sodium reacts faster withbwater,
Q:are there any other foods than water and salt that have an abiotic origin (lifeless, inorganic)?
Various minerals we need, like iron, zinc, magnesium, etc. That's it. These also are not technically foods, as the first poster said.
Q:How can experiments prove that there are inorganic salts in the leaves of plants
The experimental leaves used to dry, crushed into powder or sintered ash, and then the analysis of mineral elements, we can learn.
Q:Does the milk contain inorganic salts?
Calcium, phosphorus, potassium .1L milk can provide 1g of calcium, and milk calcium and phosphorus ratio of 1.2: 1, close to human milk (human milk 1: 1), digestion and absorption rate, it can ensure that the baby's calcium Need milk milk in the very few, only 0.2mg / 100g, for the human milk 1/5, the baby, such as milk-based food feeding, the need to timely add iron and vitamin C foods such as egg yolk, liver mud, In addition, the milk also contains copper, zinc, manganese, iodine, molybdenum and other trace element
Q:What is the risk of low inorganic salt?
Iodine content in the human body is much lower than 1/10000  is a trace element. Function  iodine in the human body to participate in the formation of thyroid. In the protein, fat, sugar metabolism  promote bio-oxidation and coordination of oxidation of phosphoric acid process, adjust the energy conversion. Promote the metabolism of sugar and fat, regulate the water and salt metabolism in the organization, promote the absorption and utilization of vitamins, activate many important enzymes, promote growth and development. Lack of disease  adult iodine deficiency can cause goiter ⑴ fetal and neonatal iodine deficiency can cause minor illnesses. Typical cases  endemic goiter and local minor illnesses. Excessive symptoms  iodine goiter, iodine thyrotoxicosis. Supply  Adult 150ug  Pregnant woman 175ug 206 Emulsifier 200ug. Food source 海 seafood seaweed, seaweed, fresh fish, clam dry, clam dry, scallops, mussels hai sea cucumber, jellyfish, lobster, etc.
Q:What foods contain inorganic salts?
Most of the food contains inorganic salts, the so-called inorganic salts, also known as minerals or ash. Minerals are naturally occurring compounds or natural elements in the crust. There are about 50 kinds of minerals in the human body, although they in the human body only 4% of body weight, but it is an essential part of the organism. Kelp, jellyfish, seaweed, moss; bones, soy products, lean meat, animal liver, brown rice and so on.
Q:The human body does not intake of minerals can be? Lack of minerals on the human body what kind of harm?
Minerals, such as calcium, phosphorus, potassium, sodium, chlorine and other minerals, iron, zinc, copper, manganese, cobalt, molybdenum, selenium, iodine, chromium and other small amount of trace elements. But no matter which elements, and the human body compared to the protein, are very small.
Q:Is bromine an inorganic salt?
It has many uses such as: · fumigants · flameproofing agents · water purification compounds · dyes · medicines · inorganic bromine (AgBr) is used in photography film · pesticides · water purification · used to make plastics flame retardant · In gold extraction...!!
