- Q: People do not eat salt tears with no inorganic salt
- I suddenly think of a science program that found a place a strange person, never drink water, then a variety of surprises. Finally, the scientist came out to explain that he can get the daily water needed from the food.
- Q: Is it possible to adjust the internal temperature of the carbohydrate in the vacuole
- The plant has no internal environment.
- 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: An inorganic salt is dissolved in water and yields a solution that has a color. Make a statement about the type of element the substance contains that casuses the color.Thanks!
- Many inorganic salts form colored solutions . pper ( II) sulfate ( Blue ) nickel (II) acetate = green, mangaanse ( II) chloride = pink, iron(III) chloride = yellow, potassium dichromate, orange and so many more Can you be more specific ?
- Q: What is the lack of inorganic salts for children?
- Children in the rapid development of the physical stage of the body, zinc consumption is very large, add must keep up, eat more fish and eggs, but not excessive.
- Q: in the ocean
- Salts are the result of the association of cations and anions. Cations are usually metals like Calcium, Sodium, Potassium anions are ususally sulfates, phosphates, carbonates...... calcium carbonate and calcium phosphate are useful in making bone. Potassium Chloride is important in heart beat regulation Sodium Chloride is important in maintaining blood pressure. Carbonate is important in blood chemistry and the transfer of energy within a cell. all these salts are found in abundance in the ocean. If you follow evolution, those salts in the ocean have given rise to our own blood chemistry and organic health.
- Q: Effects of Minerals on Plants
- Some will be plant death will help some will accumulate
- Q: Of the dissolved salts found in seawater, _____ % are minor inorganic salts, or trace.
- it's definitly one of these: 99.28 .72 72 50 i think it's 99.28. lemme no if you get it right!!
- Q: Lack of calcium, phosphorus, iron, zinc inorganic salt should eat what?
- Drinking milk is more appropriate to do a proper practice, the milk is rich in calcium, phosphorus, iron, and zinc. There is a food that is eaten inside the sea, the sea of food is basically the content of inorganic salts are relatively high.
- Q: The power of the water and inorganic salts in the plant is derived from the action of the plant
- The transpiration of plants in the body of water in the form of water vapor into the atmosphere when it is a "pump" principle, it provides a vertical pull for the root of the water, while dissolved in the water in the same salt Is absorbed and transported upward, the power is derived from the transpiration of plants
