What is an oxygen enriched environment?
Air is the mixture of gases that surrounds the Earth. The composition of the earth's atmosphere varies with altitude, but at sea level contains approximately 78% nitrogen and 21% oxygen by volume.An oxygen-deficient atmosphere contains less than 19.5% oxygen by volume.An oxygen-enriched atmosphere contains more than 23.5% oxygen by volume.
What era did autotrophic prokaryotes enrich the atmosphere with oxygen?
autotrophic prokaryotes enriched the atmosphere with oxygen in the precambrian era :) hope this helps
Can A monitoring device labeled intrinsically safe and explosion proof can be used in an oxygen enriched atmosphere?
yes
How high up does oxygen start to get thin?
Based on how oxygen flows, the higher you start to go up into the atmosphere the thinner the oxygen is and the harder it is to breath. You start to notice a difference at an altitude of 8,000 feet.
What 3 gases make air?
Oxygen, Nitrogen and Argon comprise 99% of the air.
Does a vein hold oxygen enriched blood?
Yes, a vein holds oxygen enriched blood. An artery holds deoxygenated blood.
What are atmospheres of the gaseous made of?
oxygen and helium
What is oxidized blood?
Blood that is enriched with oxygen.
What are examples of an oxygen-enriched atmosphere?
a properly calibrated oxygen monitor reading 23.9% oxygen
What is the resonant frequency of a specific volume of oxygen?
at how many atmospheres?
What materials is found in both atmospheres and the crust of earth?
Oxygen
What gas was enriched about 2.5 billion years ago?
oxygen
What two components make up of the greatest percentage of the atmospheres?
nitrogen and oxygen
Do any other planets have oxygen in their atmospheres?
Earth is the only planet known to have a significant amount of oxygen molecules in its atmosphere.
In an oxygen enriched atmosphere some possible sources of elevated oxygen levels include?
leaking oxygen cylinders and liquid oxygen systems in the immediate area

What is the difference between controlled atmosphere package and modified atmosphere package?
There is little difference between controlled and modified atmospheres. They both refer to atmospheres where the proportions of the normal gaseous/vapor components oxygen, nitrogen, carbon dioxide and water vapor, are modified to achieve some storage/packaging goal. This is commonly lowering the oxygen and/or increasing the carbon dioxide. All such atmospheres are modified atmospheres, they become controlled atmospheres when an attempt is made to regulate the composition of one or more of component gases.
