Q:Are plants absorbing water and inorganic salts only through root tip or wrong?
This is wrong.
Q:What is the physiological function of inorganic calcium
Maintain cell osmotic pressure and acid-base balance
Q:Octopus why the lack of boron-containing inorganic salts can cause rape to flow only without fruit
Boron has a great influence on the reproductive process of plants, which can accelerate pollen differentiation and pollen tube elongation. In the absence of boron, pollen tube germination is affected, poor fertilization, which leads to the formation of seeds affected, the reduction of growth hormone produced by the reduction of growth hormone will affect the formation of fruit.
Q:What is the time when the maximum number of inorganic salts is needed
Plant inorganic salts are the most nitrogen, phosphorus and potassium containing inorganic salts, if any lack of plant will affect the normal growth.
Q:How much of the body's inorganic salts account for the weight of the body?
The inorganic salts in the human body account for about 5%
Q:What is the inorganic salt, is not the organic salt and is not the inorganic salt
Inorganic salt: Acid-base reaction product without carbon element However, the chemical properties such as carbonates and carbon oxides are the same as those of inorganic substances. Therefore, they are also classified as inorganic substances
Q:is sugar and salt organic or inorganic?
Healthy compounds have carbon in them at the same time inorganic compounds should not have carbon. For example, sugar (C6H12O6) has six carbons, and is for this reason an organic compound. Water then again (H2O) does now not have a carbon in it and is an inorganic compound.
Q:Liver cancer diet should pay attention to what issues?
Balanced diet: liver cancer patients consume more, must ensure that there is enough nutrition. The easiest way to measure the nutritional status of a patient is to maintain weight. And to maintain the normal level of weight, the best way is to maintain a balanced diet, requiring patients should eat more fresh vegetables, and half should be green leafy vegetables.
Q:Why plasma osmotic pressure and protein, inorganic salt content
Plasma osmotic pressure is divided into crystalline osmotic pressure and colloid osmotic pressure.
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
