Cyanobacteria, which are sometimes incorrectly called blue-green algae, were the first organisms to add oxygen to early Earth. Blue-green algae are eukaryotes while cyanobacteria are the much earlier prokaryotes.
Stromatolites added oxygen to the atmosphere through photosynthesis. Oxygen produced by stromatolites during the Precambrian era helped to oxygenate Earth's atmosphere, paving the way for more complex forms of life to evolve.
If you just let it in, It would be 99% of ordinary air. If you send a spark through it, it would be nitrogen dioxide (it is toxic).
Yes, after backwashing a pool filter you should add diatomaceous earth (DE) back to the filter immediately if you have a DE filter. If you have a sand or cartridge filter, there is no need to add anything after backwashing.
To add an extra oxygen molecule to water, you would need to introduce a second water molecule to the chemical reaction. This can be achieved through a process called electrolysis, where an electric current is passed through water, causing it to split into hydrogen and oxygen gases. The reaction can be represented as 2H2O --> 2H2 + O2.
H2O and OH- are added to balance the oxygen atoms.
Prokaryotic cells that were the first to add significant quantities of oxygen to Earth's atmosphere are classified as cyanobacteria. Cyanobacteria are photosynthetic bacteria that played a crucial role in the Great Oxidation Event, releasing oxygen as a byproduct of photosynthesis. Their activity contributed to the oxygenation of Earth's atmosphere and paved the way for the evolution of aerobic life forms.
Plants, specifically through the process of photosynthesis, add oxygen to the atmosphere as a byproduct. During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen. This oxygen is then released into the air through a plant's leaves.
The place with the highest oxygen levels on Earth is typically at sea level, where the atmosphere is thickest. Rainforests and other dense vegetation areas also produce high levels of oxygen due to photosynthesis.
Cyanobacteria added oxygen to the atmosphere through the process of photosynthesis, fundamentally changing the composition of Earth's atmosphere and enabling the evolution of aerobic organisms.
it depends what organism but it would usually be about 2 to 5
You light the acetylene first, then you add oxygen.
When a organism dies and decays it emits carbon dioxide.
SulphurOxide.
It originates there. First you breathe in and you add oxygen to you blood streams, by the way of capillaries. It then circulates from the heart to every where else.
oxygen
YES
well first we breath in and then the oxygen enters our body after that the heart takes it and it enters the right atrium then the right ventricle and then the vale opens and the oxygen goes on and on! please add me on msp!!:)
