Carbon dioxide does not conduct electricity and can be used on electrical fires.  In theory, if you had some kind of metal fire ("Class D") that was electrically energized,  you would not want to use it (carbon dioxide will chemically react with most, if not all, burning metals and will make the fire worse).

Oxygen to carbon dioxide (breathing), food to energy, sleep to rejuvenation, or maybe that last one wasn't so good, try brain activity (thoughts) to actions (automatic brain commands that keep your heart and lungs functioning)

People tend to hyperventilate (breathe fast, without giving the body time to process the air exchange) when stressed.  This causes low levels of carbon dioxide in your blood.  In the past, the remedy was to breathe into a paper bag, thus reducing the amount of oxygen you were taking in and increasing the CO2.  Breathing through a paper bag is NO LONGER RECOMMENDED because this can quickly lead to too much carbon dioxide in your blood stream. \n\nNowadays, to increase your carbon dioxide, you need to take in less oxygen. To accomplish this, you can breath through pursed lips (as if you are blowing out a candle) or you can cover your mouth and one nostril, breathing through the other nostril.

In photosynthesis, plants convert light into chemical energy. This energy is thus used to turn carbon dioxide into carbohydrate releasing oxygen as a byproduct. That is why many plans to fix global warming such as the Kyoto Protocol aim to increase the number of forested areas through so-called carbon sinks.

One might suggest reducing carbon dioxide emissions into the atmosphere, but this is only one aspect of the problem.  \n\nWhen carbon dioxide is released, usually from sources of combustion, other chemicals and particulates are also released.  So, curbing the release of carbon dioxide from these sources would also curb the release of these otehr chemicals and particulates.   A recent study has concluded that since we have worked at cleaning up emissions and reducing particulate releases, more sunlight is reaching the surface of the earth and actually _accelerates_ the process of global warming.\n\nHonestly, the best all of us could reasonably do is to be mindful of our energy consumption habits and try to not be wasteful in what we consume and dispose of.  In conjuction with this, look at adding foliage in areas that have been stripped of plant life.  More plants will effectively remove more carbon dioxide from the lower atmosphere.

A lot, actually. The kidney and the small and large intestines are the most well-known ones. But your skin actually does it's share of excreting waste from your body too. And so do your lungs. Carbon dioxide is a waste product after all.

Well, oxygen is used for respiration, and carbon dioxide is only used for photosynthesis. Respiration should occur throughout the day for survival (duh), and photosynthesis can only occur when sunlight is present. So, the ans should be (c)

Carbon dioxide can be produced or recovered from several sources.  For food-grade carbon dioxide, most is recovered from fermentation processes, in which CO2 is a byproduct, such as ethanol production from corn.  As yeast ferments sugar into alcohol (ethanol), carbon dioxide gas is released, which is captured, filtered, compressed and sold.\n\nThere are many bulk gas distributors which sell carbon dioxide for commercial and industrial uses.  CO2 is packaged in a wide variety of sized canisters, from pocket size, to bulk tanks that are several thousand gallons in capacity.

in biology, the exchange of carbon between living organisms and the nonliving environment. Inorganic carbon dioxide in the atmosphere is converted by plants into simple carbohydrates, which are then used to produce more complex substances. Animals eat the plants and are then eaten by other animals. When these life forms die, they decay, breaking down into, among many other things, carbon dioxide, which returns to the atmosphere. Plants and animals also release carbon dioxide during respiration. Animals and some microorganisms require the carbon-containing substances from plants in order to produce energy and as a source of materials for many of their own biochemical reactions; this cycle is vital to them. The process of incorporating carbon dioxide into the molecules of living matter is called fixation. Nearly all carbon dioxide fixation is accomplished by means of photosynthesis, in which green plants form carbohydrates from carbon dioxide and water, using the energy of sunlight to drive the chemical reactions involved. Green plants use carbohydrates to build the other organic molecules that make up their cells, such as cellulose, fats, proteins, and nucleic acids. Some of these compounds require the incorporation of nitrogen (see nitrogen cycle). When carbohydrates are oxidized in cells they release the energy stored in their chemical bonds, and some of that energy is also used by the cell to drive other reactions. In the process of oxidation, or respiration, oxygen from the atmosphere (or from water) is combined with portions of the carbohydrate molecule, producing carbon dioxide and water, the compounds from which the carbohydrates were originally formed. However, not all of the carbon atoms incorporated by the plant can be returned to the atmosphere by its own respiration; some remain fixed in the organic materials that make up its cells. When the plant dies, its tissues are consumed by bacteria and other microorganisms, a process called decay. These microorganisms break down the organic molecules of the plant and use them for their own cell-building and energy needs; by their respiration more of the carbon is returned to the atmosphere. The carbon-containing molecules that an animal derives from consuming other organisms are reorganized to build its own cells or oxidized for energy by respiration, releasing carbon dioxide and water. When the animal dies it too is decayed by microorganisms, resulting in the return of more carbon to the atmosphere. Carbon-containing molecules in wood (or other dry, slow-decaying organic materials) may be oxidized by burning, or combustion, also producing carbon dioxide and water. Under conditions prevailing on earth at certain times, green plants have decayed only partially and have been transformed into fossil fuels–coal, peat, and oil. These materials are made of organic compounds formed by the plants; when burned, they too restore carbon dioxide to the atmosphere.

People use the oxygen from the air and produce carbon dioxide. Trees use carbon dioxide and product oxygen. Trees also prevent erosion, provide many food products, provide shade and create an aestetically pleasing environment.

look around "Life is chemistry"\n1- the air we breathe diffuse in our tissue so gas exchange occurs this by chemistry.\n2- the food we eat is treated with chemical cpds to kill pests (in agriculture)  & increase it's expiary (can food).\n3- plants keep our life possible on the planet by photosynthesis (it absorb CO2 & release O2) this is chemistry.\n4- chmistry used in drugs preparation.\n5- chemiacal cpds used as fertilizers,detergants,sterilizers...etc\n6- the perfume u use made by chem.\n7- chemistry control our body (enzymes,hormones,DNA etc) this is biochemistry.\n                          Finally if u look around u will found that nothing \n                                             is not chemistry.

There are several theories as to what the best method for dealing with excess carbon dioxide in the atmosphere. The one that I like the best is to turn it into rock. Yes, rock. Ever seen the Grand Canyon? It is made up of carbonate rocks. Through "relatively" simple chemical reactions, scientists can mix carbon dioxide gas with catalysts and form it into rock. Another option is to seed the ocean with powdered iron to stimulate the growth of photosynthetic (use CO2 and give off oxygen)plankton. This is an incredibly powerful method, but is also risky because we don't really understand how this will affect the food chain of the oceans. \nLastly, there is a place in Canada that is pumping carbon dioxide into the chambers left over from oil drilling. The CO2 is compressed into a "supercritical" state, where it behaves like a dense liquid. As a bonus, the CO2 helps to "push out" the oil, making the pumping more efficient. Thousands of tons of carbon dioxide have already been sequestered at just this facility. There are also huge bodies of water underground, where millions of more tons of CO2 can be sequestered.For more info, search for "carbon dioxide sequestration", as that is a common scientinfic term for what you want to do.

CO2 is the byproduct as it is given out after energy is taken by burning the food in the tissues .energy is not the byproduct of respiration.it is the ultimate product due to which we get energy to sit in frnt of the computer.lol(xcuse the bad pun)
