The aorta just as it comes out of your left ventricle.
The highest level, called Domain, contains all of the other levels, and thus by default, contains the most organisms (all of them).
The marine ecosystem has highest level of salinity.
The highest level of organization a sponge has are Cells.
First trophic level or producers or green plants or phytoplanktons have the highest biomass except aquatic ecosystems because they perform maximum photosynthesis.
Ideally you want the oxygen level at 100 percent. However, the exact level is unknown at this time as you need to be there to see if the level fluctuates.Ê
Oxygen's highest level is 100%. Oxygen's lowest level would be 20%.
Umbilical Vein, all other vessels have varying degrees of oxygenated and deoxygenated blood.
Organ
Rivers with waterfalls or rapids will have the highest oxygenation. By contrast, still waters such as placid streams, are prone to de-oxygenation processes such as algae growth.

The highest level, called Domain, contains all of the other levels, and thus by default, contains the most organisms (all of them).
The valance energy level contains 4 electrons in carbon.
The lower the percentage of oxygen air contains, the more frequent a breath must be taken in order to maintain the blood oxygen level at an acceptable level.
Water that has been exposed oxygen typically contains 2-3 millimole of oxygen.
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.
I would say the air has the highest level of oxygen but it depends how high up you are.
because their is less oxygen up in the mountains
