Answer 2

Heya..!!!

Here is your answer

Answer:

You cannot survive without oxygen because your body needs it as a component of many of its molecules. - Without it our biology wouldn't function. Imagine if all the water in your body turned into hydrogen gas.

Explanation:

The larger and more complex an organism, the more energy it needs to maintain its processes. There are no entirely anaerobic vertebrates for this reason. Even if we could somehow supply enough energy, without oxygen we wouldn't have evolved lungs and probably not a voice either, so we wouldn't look much like we do now.
