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: Please help i need the answer for a classwork assignment due today. I&#39;ve looked everywhere online but i cant find the answer.: the web page (below) discusses: Basal Salt Mixtures The use of balanced salt solution (BSS) in cell and tissue culture is generally attributed to early workers in the field. In 1885, Sydney Ringer developed a solution of inorganic salts designed to maintain contractility of mammalian heart tissue. A less specific salt solution was designed by Tyrode for use in work with primary mammalian cells. Tyrode's salt solution became the accepted fluid for diluting protein components of media of natural origin. Since that time, many other balanced salt solutions have been developed for use in cell and tissue culture. The current role of balanced salt solution in cell culture is multi-faceted and can be divided into four principle functions. see web page for extensive discussion on the good things about it

Q: What is the composition of inorganic salts?: Inorganic salts are inorganic compounds in the salt, formerly known as minerals

Q: Sodiumcorbonate is inorganic salt , why it is not organic substance even it contains carbon?: Na2CO3 is joined by ionic bond not covalent C-C bond in organic molecules. @the other answerer: LOL! maybe i should expect a TD, too. Another problem with this section is students know how to ask but never know how to say thank you. Rarely do i see an asker selecting a BA. If i see one who does, whether i get the BA or not, i will definitely answer another question from that person.

Q: Can inorganic salts act as stabilizers for emulsified asphalt?: can. The general use of calcium chloride and ammonium chloride more stable emulsifier

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: 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: Is the inorganic salt related to the excitement: Should be excited about conduction and inorganic salts. Membrane on both sides of the solution is conductive, in the excitement of the nerve segment and adjacent it is not between the excitement, due to the existence of potential difference in the charge movement, which is the local current. Its flow direction is: there is a positive charge outside the membrane has never excited to flow to the excitement section, the cell has a positive charge from the excited flow to the excitement section, the current direction is not excited to fiber membrane depolarization. When this current is strong enough to depolarize the segment to reach the threshold, a new nerve impulse - action potential is generated.

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.
