Q:The human body does not intake of minerals can be? Lack of minerals on the human body what kind of harm?: Minerals, such as calcium, phosphorus, potassium, sodium, chlorine and other minerals, iron, zinc, copper, manganese, cobalt, molybdenum, selenium, iodine, chromium and other small amount of trace elements. But no matter which elements, and the human body compared to the protein, are very small.

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:Milk food rich in nutrition, in addition to containing a variety of inorganic salts which also contain three types of organic energy can be organic: How are you

Q:A. food gathering and digestion B. photosynthesis and diatom structures C. reproduction and osmosis D. wave and current motions: its not a so try b or c those 2 are the most likely to be the right answers

Q:Magnesium can constitute chlorophyll, which reflects the nature of inorganic salts: (2) to participate in and maintain the metabolic activity of the organism.

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 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:Is it possible to adjust the internal temperature of the carbohydrate in the vacuole: multi-cell plant cells are living in the individual within the water environment, but this environment with the human body's internal environment can only be similar is not the same, and plant cells and no extracellular liquid this argument.

Q:General identification method of inorganic salts: Take the test sample, heating to remove the salt may be mixed, let cool, add water to dissolve, and then deepen .1% sodium tetraphenylborate solution and acetic acid that is white precipitate. The reaction conditions must be carried out in acidic (pH 2-6.0).

Q:What is an inorganic salt?: Encyclopedia is defined as: inorganic salts that inorganic compounds in the salt
