Coal cannot burn without oxygen.
It contracts?
You will die
Life on Earth, or at least most of it, would not exist without free oxygen. It is possible that some other form of life, based on another element, could exist in a non-oxygen environment. But none has been discovered as of now.
if............?
They need to take it with them. There is no oxygen in space
Astronauts bring tanks of oxygen with them when they go into space. The space suits they use to make space walks also have small oxygen tanks on them.
Their suits-similar to divers.
They carry it with them on board.
Oxygen is needed in our body so we can survive. The cells in our body need it and without oxygen, the cells will die and we will die. When people go in to outer space there is no oxygen so oxygen tanks are taken so the astronauts receive the oxygen they need
To breath oxygen.
Fermentation occurs in the Cytosol (cytoplasm), without oxygen.
Many types of bacteria can live in Anaerobic conditions, I.e they don't need oxygen to live, as they create energy using anaerobic respiration.
Because there is so much pressure in space, they would most likely combust if they went up without it. They also wear oxygen tanks because there is no oxygen in space.
There is no oxygen in space. Astronauts have to take oxygen with them.
astronauts will need to take air to mars because the atmosphere on the planet cannot contain any oxygen, thus no oxygen to breathe.
Capillaries must allow diffusion too allow for exchange of oxygen. Without oxygen, the eventual consequence would be death.
