Q:Is the conduction of excitement on neurons related to inorganic salts?
Neurons are cells with long synapses (axons) that consist of cell bodies and cell processes. In the long axon with a layer of sheath, composed of nerve fibers, it is a small branch of the end called nerve endings. Cell bodies are located in the brain, spinal cord and ganglion, the cell processes can be extended to the body organs and tissues. The cell body is a nuclear part of the cell, its size is very different, about 4 to 120 microns in diameter. Nuclear large and round, located in the central cell, less chromatin, nucleolus obvious. There are plaque outside the cytoplasmic chromatin (formerly known as Neil body), there are many neuronal fibers.
Q:What inorganic salts and trace elements are there in rice?
Sodium (2.40 mg) of copper (2.30 micrograms) of copper (2.10 mg) of copper (1.10 mg) of zinc (1.45 mg) of copper (2.40 micrograms)
Q:What is an inorganic salt?
I think inorganic salts mean salts that do not contain organic ionic groups
Q:The lack of three major inorganic salts can cause symptoms in the plant
P: Promote the development of seedlings and the opening of flowers so that the fruit and seed are mature early. Lack of performance: the plant is particularly short, leaves were green, and purple.
Q:Is calcium carbide inactive?
Calcium carbide, the chemical formula for the CaC2, not inorganic salts. Salt refers to the metal ions and acid ions of the compound, calcium carbide does not have the corresponding acid.
Q:Does the apple contain inorganic salts and vitamins?
Yes, the fruit is rich in these two nutrients, especially apples
Q:are acids, bases, salts and oxides belong to inorganic compound?
I think organic compunds are anything with Carbon(C), although I really don't know.
Q:What are the effects of water, inorganic salts, carbohydrates, proteins, fats and vitamins?
The main physiological functions of carbohydrates (also known as carbohydrates): 1. Supply of heat. (Per gram of sugar can release 4 kcal of calories, is the main source of heat the body.) 2. constitute the body tissue. (All the nerve tissue, cells and body fluids are still carbohydrates.) 3. Can help the oxidation of fat to help the liver detoxification, promote growth and development.
Q:During the different periods of plant growth, the amount of water and inorganic salt required is different.
Plant life, although the need for a variety of inorganic salts, but different plants on the various types of inorganic salt requirements are different, such as cabbage, spinach and other human needs leaves of vegetables need nitrogen containing inorganic salts, tomato, peanuts need phosphorus Of the inorganic salt and more, sweet potatoes, potatoes need potassium-containing inorganic salts; the same plant with the growth period of the different requirements of inorganic salts are not the same, for example, plants in the seedling period requires nitrogenous inorganic salts , In the flowering, the results of the period of time need more phosphorus-containing inorganic salts. Therefore, different plants and the same plant growth period, the need for inorganic salts are different. So the answer is: different; different
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.
