There is no single mechanical form or chemical reaction to properly describe the process that fish gills use to remove oxygen from the water and get it into their blood system.\n\nThe site below is the single best resource to cover this topic:

i don't think that any protozoan does because they are single celled organisms; gills require diffusion of oxygen across a membrane directly to the blood. protozoans don't have blood. because just about all protozoans are aquatic, they have some kind of system to get oxygen into their cells, but not gill-like.

plants use N, K and P to live. the more phosphorus(phosphate) in the water the more plants it can support. the more plants the less oxygen for fish.\nso high phosphate levels can cause low oxygen levels.

osmosis is the movement of water across a membrane. \nWikipedia on the subject: \n\n"Osmosis is the diffusion of a solvent through a selectively-permeable membrane from a region of low solute concentration to a region of high solute concentration, or in other words, from a high water concentration to a low water concentration. The higher the solute concentration the lower the water concentration will be. The selectively-permeable membrane is permeable to the solvent, but not to the solute, resulting in a chemical potential difference across the membrane which drives the diffusion. That is, the solvent flows from the side of the membrane where the solution is weakest to the side where it is strongest, until the solution on both sides of the membrane is the same strength (that is, until the chemical potential is equal on both sides)."\n\nin short, if you put the potato in fresh water, the potato cells will burst, because water will enter the cells in an attempt to equalize the concentration of salt, etc. inside the cell to what is outside the cell.. if you put a potato in salt water, the cells will shrink, because water will exit them in an attempt to equalize the concentration of salt in the cell and outside of it. I realy don't know what the temperature of water will affect though.

OSMOSIS IS THE MOVEMENT OF WATER MOLECULES ACROSS THE CELL MEMBRANE.  IF THE OSMOTIC PRESSURE IS HIGH i.e THERE ARE MORE WATER MOLECULES INSIDE THE CELL THEN WATER MOVES OUT TO LESSEN THE PRESSURE.  IF THE OSMOTIC PRESSURE IS VERY LOW THEN WATER MOLECULES MOVE INTO THE CELL TO KEEP THE PRESSURE OUTSIDE AND INSIDE EQUAL.\n\n(IT IS RUDE TO WRITE IN ALL CAPITALS)

I bet you could look this up on the web pretty easily. Why didn't you try?\n\nI bet the diffusivity is pretty good, however, because otherwise, how could fish breathe?

CELLFOOD©\n(Deutrosulfazyme) \n\nwith Dissolved Oxygen, Seawater Extract, Plant Source Amino Acids & Enzymes\n\nWinner of the 1997 Advanced Technology Award of the International Hall of Fame\n\nCellfood supports:   \nEnhanced energy levels\nCellular oxygenation\nBreathing function\nAlertness & concentration\nThe digestive process\nRemoval of lactic & uric acid\nBacteria & parasite elimination\n Immune system function\nFree-radical removal\nAllergy relief\npH balance\nNutrient absorption\nRecovery from injury\n \n\nCellfood is a unique, proprietary concentrate of 78 ionic minerals, 34 enzymes, 17 amino acids, electrolytes and dissolved oxygen, held in a negatively-charged suspension utilizing deuterium, the only non-radioactive isotope of hydrogen.  Through a process of dissociating -or splitting- water molecules within the body by weakening the bonding electrons, Cellfood releases both nascent oxygen and hydrogen into the bloodstream, and into every cell in the body.  Its developer, the atomic scientist, and inventor of the hydrogen bomb, Everett L. Storey (1914-1988), called Cellfood an electromagnetic equation.\n\nColloidal, Ionic\nBeing colloidal particles, Cellfood's ingredients are miniscule (4-7 nanometers in diameter), and because of the Brownian Movement phenomenon, they take on a negative (ionic) charge and remain suspended in liquid.  Because most bodily fluids are also colloidal and negatively charged, the body perceives Cellfood as normal healthy body fluid and allows the nutrients to pass immediately through the sensitive membranes of the mouth, throat, and esophagus directly into the blood stream.\n\nNascent Oxygen\nCellfood is unique in its ability to create nascent (meaning newly-born) oxygen.  In biochemical terms 'nascent' oxygen refers to the newly born singlet oxygen (O-) that has not yet entered the biochemical reaction.  Free radicals (which many biochemists believe are a primary cause of aging and degenerative disease) are positively charged ions of oxygen (O+).  Since nascent oxygen molecules are negatively charged, they actually seek out and attract these dangerous free radicals, combining with them to form simple pure stabilized oxygen (O2).  \n\nThis release of oxygen and hydrogen typically peaks within 8-12 hours, and can continue for up to 3 days.  The body's natural intelligence releases the oxygen and hydrogen whenever and wherever they are needed—and if no longer needed, no more is released.\n\nDi-polar, Di-basic\nCellfood was developed as a di-pole, di-base delivery system— to deliver nutrients to cells and tissues under any conditions.  Di-pole means Cellfood is effective in any polarity range of the body.  Di-base means Cellfood is effective in any pH range within the body and will tend to normalize the body's acid/base balance by delivering its 78 essential minerals as enzymatic cofactors—assisting critical enzymatic reactions to proceed optimally.  Cellfood provides an incredible oxygen source and delivery system to the body at the cellular level; and, though it is very powerful, there is no known toxicity associated with it and contains no substance banned for athletic competitions.\n\nCellfood Sources\nCellfood is derived from the clean southern seas between New Zealand and Antarctica, from nutrient-rich mineral springs, and from fossilized plants.  Each batch of Cellfood takes over 9 months to produce–through a proprietary process similar to aging fine wine. \n\nDirections\nAdults take 8 drops in 8 ounces of purified or distilled water, or 8 ounces of juice, 3 times per day–or during stress or physical activity.  Best taken between meals (at least 15 minutes before or 1 hour after ).  Each one ounce bottle of Cellfood contains 90 portions of 8 drops each, for a total of 720 drops.\n\nAbout the Expiration Date\nCellfood is shipped with a IO-year expiration date.  However, actual 25-year old samples have tested to be no less potent than when originally bottle

Osmosis is the movement of water thru a semi-permeable membrane.  Water would move from an environment of low solute concentration to an environment of high solute concentration.  Only the water molecules move, not the solutes, because the membrane is only permeable to water.  The reason that water molecules move is becaues things like to be in equilibrium.  Because the side of higher solute concentration has more matters relative to the whole system, that's why it attracts water there too.  Another way you can think about is that the side where there are more solutes provide more surface areas for the water molecules to have more contact with (more weak interactions between the water and the solutes), therefore water want to go there.  So water likes to go to where there isn't a lot of water.  (you might ask then why wouldn't the solutes move to the side that has less solute.  They won't, because your membrane is only permeable to water.)  So if you are solving problems like these, must pay close attention to the membrane permeability.\n\nDiffusion is a similar concepts.  Things like to go where there are less of them.  In the above example, because the environment has a lot of solute, BUT little water, that's why water goes to that size.  Things tend to go toward disorder (entropy), so more matters means more disorder.\n\nActive transport-this means that the movement of matters from one side to the other can only be possible if there are help, such as protein pumps.  I guess the best example is the sodium-potassium pumps.  Energy is used (main energy source is ATP) so that sodium ions and potassium ions are pumped into and out of the cell, respectively.  But again, this is also based on the concept that things tend to go to the side that there are less of them.\n\nHope that helps.  If you find some terms confusing, just go to wiki or answers.com and search for them.\nGoodluck!

they use gills. the gills are filled with lots of blood vessels.  the fish draws in water from the mouth, which passes by and out the gills. as the water moves by, the blood cells take in oxygen and the waste gases are released.

Osmosis is a special type of diffusion that only water can do.In a area of high water the water will move to a area of low water! Definition is....osmosis is a form of diffusion were water moves from a region of high water concentration to a region of low water concentration across a semi-permeable membrane!

none water is H2O two parts hydrogen 1 part oxygen any thing else the water is inpure.but in the case of fish do a 1/4 water change every week so not to shock your fish make sure you keep temp about 78 degrees or they can get ick as far as testing you dont have to test fresh water but salt water is where the nitrite cycle is critical and then you also will test ph which is idealy 8 use a hydrometer to the line as it mesures the salt level by the boyency of the device nitites no higer than 14 i belive ask you pet shop owener as it been abuot 10 years since i had my salt water tank but for fresh water, the water change should cover it.
