Q:Acids, salts, and metals are examples of?
Acids, D. water soluble inorganic chemicals salts, D. water soluble inorganic chemicals metals E. sediment
Q:Are plants absorbing water and inorganic salts only through root tip or wrong?
This is wrong.
Q:Why vegetables and fruits contain rich inorganic salts
Because they are plants! From the biological point of view, they are the nature of the organic matter into inorganic salt carrier
Q:The lack of three major inorganic salts can cause symptoms in the plant
Nitrogen: to promote cell division and growth, so that leaves grow lush. Lack of performance: plant thin and thin, leaves yellow, severe leaves were light brown.
Q:What substances can detect inorganic salts
To see what inorganic salt, and mainly to test metal ions. Since it is sweat, then the main salt, that is, NaCl, which is detected NA + and CL-.
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:Definition of inorganic salts
There are about 21 kinds of elements which have important physiological functions in the body. Among them, calcium, magnesium, potassium, sodium, phosphorus, sulfur and chlorine are more and more, and the amount of inorganic compounds is more Iron, copper, iodine, zinc, manganese, selenium, fluorine, chromium, nickel, molybdenum, silicon, tin, vanadium and cobalt content is extremely small, called trace elements .2, inorganic compounds in the general name of the salt. Formerly known as "minerals." Some elements of inorganic salts for the human essential nutrients, including potassium, sodium, calcium, phosphorus, iron, iodine and other 20 kinds of elements. With the maintenance of cells and liquid normal osmotic pressure, maintenance of neuromuscular excitement As a variety of acid system activator; constitute the ester of the base; hormones, vitamins, nucleic acid composition and regulate the body's acid and alkali balance and other important physiological functions. Increased or lack of disease, such as hyperkalemia, The explanation of the "inorganic salts" in the academic literature
Q:Nutritional characteristics of carbohydrates and inorganic salts in vegetables
Inorganic salts are absorbed and utilized by crops in the soil. Carbohydrates are composed of carbon (C) and water (H20). Each person's body contains carbohydrates.
Q:Inorganic salt function
Ca2 + is the animal bone and teeth (containing CaCO3) composition, and blood coagulation and muscle contraction has a regulatory role, if the content is too low, the animal will appear muscle twitch. K + is a variety of enzyme activator, for the plant starch and protein synthesis and animal nerve impulse conduction and muscle contraction also plays an important role. Fe is a component of hemoglobin and cytochrome, and iron-containing enzymes are indispensable when chlorophyll is formed in plants. Another example is Na + for animal heart beat, nerve excitement is indispensable.
Q:RO reverse osmosis water machine can remove impurities in the water, that the body will not be due to lack of minerals and malnutrition?
So we can say: all the minerals required by the human body are dependent on the supply of food.If the mineral and water pollutants to do comparison, then we can almost ignore the minerals in the water; , We would rather drink RO reverse osmosis water machine filtered out of the clean water, do not for that 0.01% of the minerals, and take our health joke.
