Q:Common inorganic salt ions will appear when the corresponding symptoms
Zinc ion: growth and development, taste development disorders
Q:Which crop feet can provide C N inorganic salts for fungal growth
Plant growth requires a variety of inorganic salts, which require the most is nitrogen, phosphorus, potassium containing inorganic salts. If a lack of some inorganic salts, plants can not grow normally. Kind of crops need fertilization, farm manure contains organic matter, the microbial decomposition of the soil will produce a large number of inorganic salts for plant growth and utilization, the role of fertilizer is to provide a variety of plant growth of inorganic salts. Therefore, in agricultural production, the application of fertilizer and farm manure is intended to provide a variety of inorganic salts for crops.
Q:What inorganic salts and trace elements are there in rice?
Pantothenic acid (0.60 mg) Carbohydrate (76.80 grams) Folic acid (3.80 micrograms) Dietary fiber (0.60 grams) Biotin (220.00 micrograms) Thiamine (0.33 mg)
Q:The effect of inorganic salt medium and the difference with enrichment medium
The landlord said the basic nutrient base? That is based on the inorganic salt with carbon source and energy sources, such as beef extract, peptone, etc., the basic nutrients can provide the necessary cells to grow cells.
Q:What is the disease of inorganic salt crystals?
Drink less, the urine will be reduced, the urine of the inorganic salt concentration will be high, the discharge of urine encountered outside the cold air, will immediately cool, urine inorganic salts to precipitate down, so that urine Into the lime watery white turbid liquid. Check this urine, the urine heated to a certain temperature will make it clear; also due to temporary urine alkalization caused by white turbid urine, such as taking alkaline drugs or After a lot of alkaline food, or eat can make the inorganic salt in the urine of the increase in the content of food, fruit, vegetables, there will be white urine.
Q:How does inorganic salts maintain osmotic pressure and pH
Osmotic pressure to the concentration of inorganic salts affect the distribution of water molecules inside and outside the cell ~ to adjust the osmotic pressure, when the extracellular fluid concentration is greater than the intracellular fluid when the performance of water loss, otherwise the water.
Q:Inorganic salt of the inorganic salt function
Some inorganic salts are an important part of some of the complex compounds in the cell.
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:I am an AP biology student testing how magnesium effects the rate of photosynthesis in a plant. However since my class period is only one hour long I highly doubt if i add epsom salt to the soil ( after mixing it with water) i will see an immediate increase in the rate of photosynthesis. So i need to know how long should i wait to test photosynthesis rates after adding an epsom salt solution to the soil of a plant. Or how long does it take for magnesium to be incorporated into a plants rate of photosynthesis. Thanks in Advance!
Magnesium sulfate (or magnesium sulphate) is an inorganic salt (chemical compound) containing magnesium, sulfur and oxygen, with the formula MgSO4. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO4·7H2O), commonly called Epsom salt, Magnesium is part of the chlorophyll in all green plants and essential for photosynthesis. It also helps activate many plant enzymes needed for growth. Rate of photosynthesis does not depend upon any single factor . so it is futile to expect it should increase after addition of epsom salt to soil in solution form . Because first it should be incorporated in chlorophyll molecule . That depends upon formation of new leaves . Old leaves already have it ( formula of chlrophyll a = C55 H72 O5 N4 mg ) That is the requirement is just one atom per molecule . what to do with excess ? Unless the soil is deficient in Mg . It it useless to add it . soil pH is another factor to be considered = Soil pH (a measure of the acidity or alkalinity of the soil) Soil pH is one of the most important soil properties that affects the availability of nutrients. Macronutrients tend to be less available in soils with low pH. Micronutrients tend to be less available in soils with high pH. www.ncagr /cyber/kidswrld/plan...
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.
