Pure oxygen is a gas that only contains oxygen - and nothing else. Oxygen is pure when a certain mass (or volume) of it contains no other elements.
As I wrote the above, someone else suggested pure oxygen was pure air. Air on earth is mostly nitrogen (about 75%), 20% oxygen, with smaller amounts of argon, water vapor, CO2, and other gasses.
water and oxygen. Then us humans can use use the water and the oxygen and in return we breathe out carbon dioxide, which plants can use.
Oxygen, nitrogen, and argon are obtained by fractional distillation for industrial use. This process involves separating air into its components based on their boiling points, with oxygen, nitrogen, and argon being the main products obtained for various industrial applications.
Oxygen is the waste product produced during photosynthesis that humans use daily for respiration. Oxygen is essential for the survival of all aerobic organisms, including humans, as it is required for cellular respiration to produce energy.
Oxygen is the gas humans and animals need to breathe in.
Through a process called photosynthesis.
"Oxygen is obtained for industrial use by the fractional distillation of liquid air, by the electrolysis of water, or by heating manganese oxide with potassium chlorate.
Terrible grammar. Either the asker does not speek English or is mentally challenged. I will slowly answer this question the best that I can. Humans... use oxygen... to breathe... If humans could not breathe they could not do anything industrial! That is "how humans you use oxygen in industry". They breathe it. You should try it. Your brain could use some oxygen numbnut!
Most reptiles use diffusion through the skin to obtained oxygen.
Lungs
oxygen
its denser than oxygen and our bodys werent ment to use it
Oxygen is obtained by inhaling or breathing. This motion takes oxygen down to your lungs, and to small sacs call alveoli where oxygen is transmitted into the blood.
Obtained by Earths atmosphere which is 20% Oxygen and processed by the aveoli (part of the lung).
water and oxygen. Then us humans can use use the water and the oxygen and in return we breathe out carbon dioxide, which plants can use.
Humans use their respiratory system to breathe in oxygen from the air and release carbon dioxide as waste. This process occurs in the lungs where oxygen from the air is absorbed into the bloodstream and carbon dioxide is removed from the body.
That means that oxygen is necessary for life to survive. Humans need oxygen to breathe and use for cellular respiration.
Most animals, including mammals, birds, fish, insects, and some reptiles, use oxygen for respiration. Additionally, many plants also require oxygen for cellular respiration, although they primarily produce oxygen through photosynthesis. Microorganisms like bacteria and fungi can also use oxygen for growth and metabolism.
