Why do rockets carry oxygen into space?
There is no free oxygen in space, so they need to carry oxygen with them to allow their fuel to burn and, in the case of manned spacecraft, for the crew to breathe.
Does a fire have oxygen?
Yes, most fires need oxygen to burn (combustion is a rapid form of oxidation). If there is no continuous supply of oxygen, a fire will go out.
Which chemical reduces oxygen in the blood causing a difference between the amount of oxygen the cells need and the amount of oxygen the blood cell can supply?
carbon monoxide.
Why do you need oxygen in space to make fire?
Fire needs oxygen no matter where it is. It is a chemical reaction between oxygen and some flammable substance. On Earth, the air is already 21% oxygen, so you only need to supply the fuel. In space there is no air and thus no oxygen, so you need to bring oxygen or some comparable oxidizer with you.
Why does a lit candle go out when a inverted beaker is on it?
When the inverted beaker is placed over the candle, It cuts off the oxygen supply. All flames need oxygen to continue burning.
Why do rockets need to carry a supply of oxygen?
Rockets need to carry a steady supply of oxygen so that the fire that takes them off of the ground can burn. You must remember that to have fire you must have oxygen.
What does the human body need a steady supply of?
oxygen
Why do rockets carry oxygen into space?

Why do animals need a continuous supply of oxygen?
Animals need a continuous supply of oxygen because it obtains energy from their food. To acquire such energy from food, cells in animals require a steady supply of ATP in order to function. To produce this ATP, cellular respiration requires oxygen. Without ATP, cells and the organism will die so therefore, animals need a continuous supply of oxygen to survive.
The basic funcction of respiration is to supply the body's need for?
Oxygen.
Why do you need coronary arteries?
to supply your heart with blood and oxygen.
At what height do they need to supply oxygen in a plane?
10000 feet
Why does the brain need a constant supply of oxygen and glucose?
because
What is the difference in propultion between an airplane a spacecraft?
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).
Why does oxygen diffusion rate increase?
Oxygen diffusion increases as the need increases. It is a matter of supply and demand.
How do tissues get the oxygen they need for energy production?
The tissues get oxygen from oxygenated blood supply for energy production.
Do plants need air?
Yes, to supply them with Oxygen and Carbon Dioxide.
