What allotrope of this element is being depleted from earth's stratosphere?
oxygen
Is the greatest amount of gas in the air oxygen?
No it isn't. It is Nitrogen, which makes up 70% of the air we breathe.
What causes soil types to be different from place to place?
The amount of oxygen in the air
How the amount of oxygen in the atmosphere affects respiration?
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.
What percentage of each gas is in the air?
When you inhale air the concentration is abut 21% of oxygen but in your lungs some of it gets consumed and replaced by carbon dioxide the concentration of exhaled oxygen depends on your metabolism and oxygen consumption.
Where does veins carry oxygen depleted blood to?
Veins carry oxygen depleted blood to the heart.
What is the amount of oxygen in the atmosphere?
Air is 20.5 percent oxygen.
What do you think will happen to animals and humans if the amount of oxygen in the air is reduced?
What do you think will happen to animals and humans if the amount of oxygen in the air is reduced?
Depleted of oxygen?
Hypoxia is the term used for low, or depleted, oxygen levels. It occurs naturally at high altitudes or in the deeper regions of the sea.
What is deficient amount of oxygen in inspired air?
hypoxia
Is all the oxygen you inhale used by your body?
You don't use all of it but you do use a lot of it i am not 100% certain how much you use though

Air is mostly made up of nitrogen. Oxygen is the second largest amount in air. Carbon dioxide is the third largest amount in air. Hope this helps!
How does a runner acquire an oxygen debt?
The term oxygen debt was adopted to explain anaerobic energy expenditure following intense physical exercise. The amount of oxygen required to reoxidize the lactose acid manufactured as well as to restock depleted ATP stores.
Why you inhale oxygen only?
when you inhale air into your lungs the concentration of oxygen in the blood can be no greater than that in the air.As the blood reaching the lungs is lower in oxygen there is transfer from the air to the blood stream until the concentrations stabilise.However there is no active transfer.Therefore there will always be Oxygen in exhaled air even if the initial oxygen concentration in the blood is zero as the air oxygen and the blood oxygen will reach a steady state equilibrium
