Spacecrafts need internal oxygen supplies because there is no oxygen in space.
Rockets need to carry their own supply of oxygen because they travel through the vacuum of space where there is no atmosphere to provide oxygen for combustion. By carrying their own oxidizer, such as liquid oxygen, rockets can generate the thrust needed to propel themselves forward.
No, eliminating the supply of oxygen from the air would not kill off a virus because viruses do not require or consume oxygen to survive. Viruses need a living host cell to replicate and cannot survive for long outside of a host organism.
Humans need oxygen to survive. Oxygen is necessary for cellular respiration, which allows our cells to produce energy. Without a steady supply of oxygen, our organs and tissues would not function properly.
Man needs oxygen to survive. Oxygen is essential for cellular respiration, which produces energy for the body's processes. Without a constant supply of oxygen, humans cannot survive.
The left side of the heart is rich in oxygen because it receives blood from the lungs, where it picks up oxygen through gas exchange. This oxygen-rich blood is then pumped out to the rest of the body to supply tissues with the oxygen they need for cellular function.
because there is no, repeat NO oxygen in outer space. since oxygen is the gas we live on, we need it to keep our heart pumping. And since there's no oxygen in space, therefore you need a supply of oxygen brought from earth.
The moon has a very thin atmosphere with no oxygen. Therefore, there is no natural oxygen supply on the moon. Humans would need to bring their own oxygen supply if they were to visit or live on the moon.
oxygen
Yes, you need oxygen to survive in space because there is no breathable air in space. Astronauts rely on spacesuits or spacecraft with life support systems to provide them with oxygen to breathe.
10000 feet
to supply your heart with blood and oxygen.
Oxygen.
Yes, to supply them with Oxygen and Carbon Dioxide.
Oxygen & Glucose
Oxygen diffusion increases as the need increases. It is a matter of supply and demand.
The tissues get oxygen from oxygenated blood supply for energy production.
A spacecraft need a rocket engine (which is powered by on-board oxygen and fuel) to propel itself, an airplane only needs a jet engine (which only needs on-board fuel as it uses oxygen form the air).
