Q:Please tell in your own language how water and inorganic salts are transported from the soil to the leaves.
The roots of plants are usually divided into roots, roots, roots, roots (roots, roots and roots) for the absorption of roots, the absorption of roots from the soil to absorb water and inorganic salts, through the transport organization to reach the xylem catheter, through the catheter To the various organs of the plant (including leaves). The effect of the absorption of roots through the semipermeable membrane of the role of penetration, that is, the concentration inside and outside the cell membrane is poor. Transpiration can provide transport power for the transport tissue, like a pump to the water and water carrying inorganic salts to the top of the plant. Or first through the root absorption, and then through to the transport.
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:Plant needs the largest amount of the three major inorganic salts have any effect
Q:Does the urine and urine contain inorganic salts? Anxious
Analysis: This question can be solved from the formation of urine. Kidney is the formation of urine organs, nephrons are the basic unit of renal structure and function, nephrons include glomerular, renal sac and renal tubules; urine formation process, including filtration, reabsorption and secretion of three processes.
Q:Is the inorganic salt related to the excitement
Human or animal body nerve cells are stimulated, excited in the form of electrical signals in the nerve fiber conduction process.
Q:what is the function of salts in DNA extraction?
The role of the salt is to neutralize the charge of the DNA's sugar phosphate backbone. This makes the DNA less hydrophilic (less soluble in water). Ethanol has a lower dielectric constant than water so it's used to promote ionic bonds between the Na+ (from the salt) and the PO3- (from the DNA backbone) causing the DNA to precipitate, to extract DNA finally..
Q:Determination of the existence of inorganic salts in the soil, in the filter, should pay attention to the matter
Two low: filter edge is lower than the edge of the funnel;
Q:Cells are composed of water and inorganic salts or by organic matter and none
Cells are composed of water and inorganic salts or b
Q:The power of the water and inorganic salts in the plant is derived from the action of the plant
The main process is: soil moisture → root hair → root catheter → stem catheter → leaf catheter → stomata → atmosphere.
Q:Can inorganic salts be tested by LC / MS?
LC-MS mass spectrometer for organic matter, inorganic salts can not be atomized not applicable, and will pollute the instrument.
