I think they would breathe with carbon dioxide and would live on mars.
echinoderms, cnidaria and other forms
Yes, the word 'survival' is a noun form of the verb to survive. Other noun forms of the verb to survive are survivor and the gerund, surviving.
Venus and Mars are the only other solid bodies in the solar system with atmospheres dense enough to "breathe", but neither contains nearly enough oxygen for a human to survive on.
so far all we know was that the water was high and the ground was low but other than that we have no clue about anything else and this is a 12 year old answering this! :)
plants and animals need each other to survive.
when you breathe out, plants breathe in.
Plants need carbon dioxide as much as we need oxygen. If there isn't any air in space for us to breathe, plants can't survive. Plus, we don't know what any other galaxies are like right now.
They have been found to survive primarily on voles in the Tundra when no other life-forms are available.
The Romans did not invent medicine. Forms of medicine already existed in the Mesopotamian civilisations and in Egypt and Greece. There were also forms of ancient medicine in India, China and other parts of the word.
Many people in big cities breathe polluted air. Why? - the pollution is mixed with the air you breathe. =============================== "Can you breathe it?" is not the question you want to ask. You can breathe anything that's in the form of a gas, or particles dispersed in gas ... carbon dioxide, helium, carbon monoxide, steam, nerve gas, tobacco smoke, alpha-particle plasma, etc. For any gas, the question you want to ask is "How long can you survive while you breathe it ?" You cannot survive as long breathing polluted air as you can survive breathing clean air. In other words, polluted air kills people. Not in a minute, not in an hour, and not in a day. But people don't live as long in polluted air, and that's exactly the same as saying that polluted air kills people.
They can survive in areas of the earth where no other life forms can be found. For example, some of them can't survive in oxygen, and others are found deep inside the ocean vents.
