what are the differences among solvents,solutes, and the the solutions in the body?

The solute is the substance which is least fluid, usually a powder or, say, the actual blood cells. The solvent is the lower viscosity medium in which the solute is mixed, for example plasma is the solvent in blood, where the blood cells are the solute. The total combination (blood) is called the solution.\n\nNot sure if you were looking for the explanation of the definitions or not.

The two major classes of molecules in our body: \n1. Organic: these are any molecules that have carbon atoms in them, like proteins, carbohydrates, and nucleic acids (DNA, RNA).  \n2. Inorganic: these are any molecules that do not have carbon atoms in them, like water and minerals.

That's a HUGE question you're asking, if I understand it correctly.  While the body is made up mostly of water, there's also an *enormous* number of biochemicals in the human body working in extremely complex ways, all of which affect human behavior, from whether your hungry to the color of your eyes to whether you're alive or dead.  Even biochemists don't know yet exactly what they all are and how they all work.\n\nA (very) partial list:\n\nhemoglobin\nserotonin\nbrain natriuretic peptide\nadenosine triphosphate\nacid phosphatase\nD-oxy-ribonucleic acid (DNA)\ntriglyceride\npyruvate dehydrogenase\nsuccinyl coenzyme-A synthetase\n1-aminocyclopropane-1-carboxylic acid\nbacteriorhodopsin\nbeta-hydroxy beta-methylbutyrate\nfarnesyl pyrophosphate, geranyl pyrophosphate and other acyclic sesquiterpines\n\n...to name a very few.

Electrolytes- compounds which when dissolved in water produce solutions that conduct an electric current. \n\nNonelectrolytes- compounds which when dissolved in water produce solutions that do not conduct an electric current.

useful substances enter and waste products exit of course.\nuseful substances include glucose, oxygen, amino acids, etc.\nwaste products would be carbon dioxide, urea, etc.

I think that what is troubling you could be an exerecise involving "molarity" which uses two quantities: mass(moles)/volume(liter). \nBut you have to bear in mind that mass is referred to the solute, and volume refers to the solution. So, these quantities are not referring to ONE substance. \nIt would be better if you posted a question with the whole exercise, for clarity. \nGood luck.

IF substance contains both hydrophobic and hydrophilic parts:\n  Make the part that is soluble in polar solvents i.e the part having polarity in water and rest in some nonpolar solvent.\n\nIFsubstance is purely ionic represent it as ions in water.

damn! i should know this...i'm a science chem/bio student\n\ngimme some time...they are basic and acidic in nature. so in solution, there's the [H] ions for reaction in/around cells

Osmolality:  The concentration of particles dissolved in a fluid. The osmolality of serum can help diagnose several medical conditions such as dehydration, diabetes, and shock.\n\nOsmolarity:  regarding people with DI, osmolarity is the direct measurement of the concentration of dissolved substances in urine. In general, osmolarity is the concentration of an osmotic solution especially when measured in osmols or milliosmols per liter of solution.\n\nthere ya go :)

Most chemical reactions, both in nature and in the laboratory, take place in a solution.\n\nFor ionic chemicals, it is the polarity of the solvent (usually water) which allows the separation of the ions so that the reaction can take place.\n\nFor non-polar chemicals, the solvent (often a non-polar one) allows for the chemicals to come into contact with one another and to regulate the speed at which the reaction takes place.\n\nAll biological chemistry depends upon reactions which take place in water (as a solvent).  This is especially true of reactions involving enzymes.

To perform a solution-based separation, you need a solvent in which one or some of the solutes (in the mixture to be separated) is/are highly soluble, and in which the other components are highly insoluble.\n\nA simple example might be separating an ethanol/pentane mixture by using water.  Ethanol, being polar, will readily dissolve in water; but the nonpolar pentane will not.

If you mean to ask what the difference between a solution and a suspension is, then a solution is when the solute is dissolved into the solvent completely, and a suspension is when energy must be constantly applied to the mixture in order to keep it mixed up (like shaking, stirring, etc.)\n\nHope this helps...

I agree with the first poster on C and E, but I'm not sure if A is also.  A solute dissolving in a solvent seems like a chemical process to me, but I don't remember for sure.
