A rocket engine carries its own supply of oxidizer, which provides the oxygen needed for combustion to occur. This allows rockets to operate in the vacuum of space where there is no external source of oxygen.
That is, what they already do. No kind of fire can burn without oxygen!
The oxygen atom in a polar water molecule carries a partial negative charge. This is because oxygen is more electronegative than hydrogen, leading to an unequal sharing of electrons in the covalent bonds.
Anaerobic bacteria are unable to tolerate oxygen. They can only survive in environments without oxygen or in low oxygen conditions.
Oxygen typically has a negative charge when it forms ions, such as in the case of the oxide ion (O2-). In its neutral state, oxygen atoms do not have a net charge.
Oxygen is a gas under ordinary conditions.
Blood carries red blood cells which carries blood around your body
Red blood cells
Fixed supply is the kind of supply which is not expected to run out in the near future. For example, oxygen and sunlight can be said to have fixed supply.
it carries food,the oxygen tank and some things astronauts need
The red blood cells in the circulatory system carry oxygen from the lungs to all the cells in the body. This transportation of oxygen is facilitated by the protein hemoglobin found in red blood cells.
The pulmonary veins are high in oxygen and low in carbon dioxide. All other veins are high in carbon dioxide and low in oxygen.
arteries carry oxygen rich blood out of the heart and veins carry oxygen deprived blood back to th heart
Thomas is a steam driven tank engine. A tank engine is a locomotive that carries water in either one or two tanks, rather than towing a water and fuel tender.
it increases their oxygen supply
That is, what they already do. No kind of fire can burn without oxygen!
Inadequate oxygen supply to tissues is known as hypoxia, of which there are 4 kinds. The kind that is due to a reduction of functional hemoglobin is known as anemic hypoxia
The oxygen atom in a polar water molecule carries a partial negative charge. This is because oxygen is more electronegative than hydrogen, leading to an unequal sharing of electrons in the covalent bonds.
