Yes, it is true because the density of oxygen is higher than the density of nitrogen.

Does chronic bleeding ulcer increase erythropoiesis?
increased demand for oxygen
If the temperature is increased What happens to the partial pressure of oxygen in a sample of air?
In a sample of air, an increase in temperature will result in an increase in the partial pressure of oxygen.
If you burn copper in oxygen will the weight increase or decrease?
An oxide is formed and the mass is increased.
Why has oxygen increased?
Pt has congential heart diease and is terminally ill was coping on 4litres now on eight litres what will be the result of the increase in oxygen
Which of the following factors would increase the amount of oxygen discharged by hemoglobin to peripheral tissues?
decreased pH, increased temperature or increased levels of CO2
What is the most effective way to increase the oxygen content of air?
increase current global forest cover by 10 percent
Why is the concentration of helium increased in some gas mixtures that drivers breath in order to reduce patial pressure of oxygen?
The concentration of helium is increased in some gas mixtures to reduce the partial pressure of oxygen because helium is a low-density gas that is less soluble in the blood than nitrogen. By replacing nitrogen with helium, the overall density of the gas mixture is reduced, which helps to decrease the work of breathing. This is particularly beneficial in diving situations, where high pressures can increase the risk of nitrogen narcosis and oxygen toxicity.
What will happen if the oxygen in the atmosphere is 21 percent?
Oxygen is already 20.946% by volume, So an increase of 0.054% should not make any difference
Why did the amount of oxygen's in earths atmosphere increase dramatically?
The amount of oxygen in the atmosphere increased because the number of photosynthetic organisms, which release oxygen, on the earth dramatically increased. This lead to the Great Oxygenation Event, or the Oxygen Crisis, 2.4 billion years ago - when this free O2 entered the Earth's atmosphere.
Why does breathing rate increase at a high altitude?
At high altitude, there is less oxygen, so breathing rate is increased to compensate.
What is the density of the Oxygen?
Density of oxygen is 1.429 (g/cm3)
What caused the proportion of oxygen in the atmosphere to increase?
Plants started to grow on the earth, plants breath in carbon dioxide (which is why it decreased so much) and they breath out oxygen. That is why the percentage of oxygen has increased so much.
