yes.
There was no oxygen in the beginning. Plant life developed and released oxygen gas into the atmosphere over a long period of time.If that had never happened, there would not be much if any free oxygen in the atmosphere and aminal life as we know it would never have developed.
fishes take in water and remove oxygen from it.....thats how they breathe....
They need oxygen definitely to survive. They get this from filtration through their gills. As far as light is concerned, they do not need light to survive as many live below the layer in the ocean that light can permeate. There are fish that lice in total darkness. They have adapted over the years to exist in these conditions.
Oxygen partially dissolves in water. Respiratory systems of aquatic animals are adapted to get this dissolved oxygen. They have gills for respiration.
Oxygen and glucose
Oxygen can exist in Lewis's basement.
Oxygen Fluoride which does not exist, but oxygen difluoride does exist. However, it is very reactive. It is a very strong oxidizer.
Oxygen has a diatomic molecule and ozone a triatomic molecule.But also monoatomic oxygen exist.
oxygen
No one would be here today if there was no oxygen.
Oxygen can exist as a solid at very low temperatures, below -219 degrees Celsius. In this state, it forms a blue-colored crystal known as solid oxygen.
Such a compound does not exist.
molecules
Life on Earth, or at least most of it, would not exist without free oxygen. It is possible that some other form of life, based on another element, could exist in a non-oxygen environment. But none has been discovered as of now.
Oxygen can exist on its own as a diatomic molecule, O2, or it can form compounds with other elements. In nature, oxygen is commonly found in both elemental form and in various compounds.
it can exist alone as a diatomic molecule eg O2 oxygen
Yes, oxygen can exist in a liquid state at very low temperatures. Oxygen liquefies at around -183°C under normal atmospheric pressure. Liquid oxygen is used in various industrial and medical applications.
