What is having to do without oxygen?
When a process or organism doesn't require oxygen it is called anaerobic, or sometimes facultatively anaerobic depending on the specific organism. Another term for without oxygen is anoxic.
The formation of coal and oil?
Formation of CoalAbout 300 million years ago, large areas of the Earth's land area were covered in dense peat swamps. Over time, the peat in the swamps was buried, and forced deep underground. Extreme pressure and heat eventually turned the peat into soft coal, and later some if that became hard coal also as a result of heat and pressure.Formation of OilHundreds of millions of years ago, there were periods of time when carbon dioxide levels rose high enough to cause anoxic (very low oxygen) conditions in areas of the oceans. Algae thrived, but when it died simply sank to the bottom where it didn't decompose. Massive layers of these dead algae built up without rotting and were eventually buried by sediment. As the layers became deeper and deeper, heat and pressure transformed the algae deposits into kerogen (a premature form of oil found in rocks known as oil shale) and later petroleum.
Is pine tar edible?
Do NOT eat pine tar!However, there are many reasonable and old-time uses for it.Pine tar is a sticky material produced by the high temperature carbonization of pine wood in anoxic conditions (dry distillation or destructive distillation). The wood is rapidly decomposed by applying heat and pressure in a closed container; the primary resulting products are charcoal and pine tar.Pine tar consists primarily of aromatic hydrocarbons, tar acids and tar bases. Components of tar vary according to the pyrolytic process (e.g. method, duration, temperature) and origin of the wood (e.g. age of pine trees, type of soil and moisture conditions during tree growth). The choice of wood, design of kiln, burning and collection of the tar can vary. Only pine stumps and roots are used in the traditional production of pine tar.Pine tar has a long history as a wood preservative, as a wood sealant for maritime use, in roofing construction and maintenance, in soaps such as Packer's Pine Tar Soap and in the treatment of carbuncles and skin diseases, such as psoriasis, eczema, and rosacea.But don't eat it, please. It will make you very, very sick. I know it smells good, but put the pine tar jar away now.......
What are Anoxic conditions?
Anaerobic means able to live without air or oxygen, like some bacteria. One example is botulism. In human metabolism, the term anaerobic applies to ATP use and glycosis to provide energy in the muscle cells. This does not require oxygen, but is rapidly depleted and can result in a buildup of lactic acid in the cells.
Lake water chemistry vs river water chemistry?
It all depends on the rate of flow... in a lake the water is calm, and the deeper the lake water is the less dissolved gas content changes- a lake has various layers, in it colder denser water stays at the bottom (below the warmer less dense water) - these layers tend not to mix so as the bottom layers of water have the dissolved oxygen removed from the water by biologic processes (decompostion of dead plant material by microbes, fish beatheing, etc.) the oxygen is depleated and the water becomes anoxic (oxygen deprived) this allows for the accumulation of biologic matter in vast quanties (think of fresh water swamps- the leaves don't decompose) after a good amount of sediment fills the lake up from various depositional episodes the bio-matter will become peat, and given even more time it can become coal or 'oil shale' like in certain ancient lake deposits out west (ex: Green River Basin, Piceance Basin of Colorado, etc.) In some extreme cases of super anoxic lakes the carbon dioxide levels are dangerously high (as in go down there and the acidity of the water will start to eat your scuba gear and you!) but this usually happens in lakes in volcanic systems (lake Nyos in Cameroon (Africa) is probably the most famous one in the world: the CO2 levels got so high in the lake (the gas seeped up out of the ground at the lakes bottom) than on August 21, 1986 when the water layers at the bottom of the lake were disturbed (probably an earthquake or land slide) the water column destabilized (like when you open a bottle of Coca-Cola after it has been shaken it explodes) releasing almost all of the CO2 gas dissolved in the lake… because CO2 gas much denser than regular air it poured down the valley that the lake was in suffocating 1700 people and countless live stock over a path of 15 miles…) also for lakes... generally rivers or streams pour sediments into them at high or moderate rates, once the speed of the water slows the suspended sediments drop out (larger grains (slits) at first then smaller (clays))this will cause a difference in stream vs. lake water chemistry The location of a lake is also very important if it is in the middle of a dranage system that does no release its water (like the Great Salt Lake of Utah or the Caspian Sea) the salt concentrations are very high, as rocks erode salt is released at a fairly constant rate, and if water is evaporating from said lake then the salt that is being put in it at very small amounts will become concentrated. for steams the chemistry the water is turbulent so lots suspended sediments an a fair amount of gasses like oxygen from the air are dissolved in it, also if the water is slightly acidic it can dissolve limestone (calcium carbonate). bicarbonate ions (HCO3-) and carbonate ions (CO32-) together make up almost 50% of total dissolved solids in average river water By the way this was a geology question, but chemistry has a lot to do with it … Make sure you find all of this data for yourself if you are doing a report, use wikipedia to point you in the right direction or use google scholar (this gives you real sources not blog garbage)- not saying this is or anything... http://scholar.google.com/schhp?ie=UTF-8&rlz=1T4GGIK_en___US273&hl=en&tab=ws
Can plants live in anoxic soil?
Yes plants can live in anoxic soil. an example of a plant that can live in anoxic soil is the mangrove. A mangrove can live in anoxic soil because of little arial roots called pnuematophores that are not submerged by water during the day, this allows them to draw oxygen into the underground root system.
What rhymes with anoxic?
Toxic.
Does pleurococcus photosynthesise?
yes, anoxic photosynthesis
The difference between oxic and anoxic soil?
Soil that contains oxygen is known as oxic soil. On other hand soil which lacks the oxygen is known as anoxic soil
What are the main causes for anoxic brain injury?
The main causes for anoxic brain injury are lack of oxygen to the brain. This can be caused due to drowning, suffocation, shock or autoerotic asphyxiation.
What is without oxygen?
The terms for without oxygen are anaerobic or anoxic.
What is Stagnation deposits?
decreased microbial decomposition, often anoxic.
What is the difference between anoxic and anaerobic condition?
Anaerobic = total absence of free oxygen (O2) or bound oxygen (NO2, NO3) Anoxic = absence of free oxygen, but presence of bound oxygen.
When did the earth go from anoxic to oxic?
around about 2000 million years ago
What term is used to describe water with too little oxygen to support life?
Anoxic.
Do all of the steps of cellular respiration need oxygen?
No; and those that do not are called anoxic steps.
What do we call a situation the cells are not receiving enough oxygen?
oxygen deprivation or anoxic (depending on degree)
