Yes, you can die from a low oxygen level, this is called anoxia.
fish will die
When oxygen levels in water get low... When algae takes over a lake. The oxygen levels will get low.
The air pressure would be very high, and we might die because of it. There might be low in oxygen because the atmosphere is very thin.
not unless you smoke it out in a room with low oxygen (death by suffocation) or unless your stuff is laced
Oxygen stays as diatomic molecules in the atmosphere. These 2 oxygen atoms are bond with a double bond. So reactivity of oxygen is low.
Deoxygenated blood is low in oxygen and high in carbon dioxide.
No energy, hard to think, fever, terrible, terrible headache. Source: My experience, I went into the hospital with a hemoglobin level of 4.5. Doctors couldn't believe I was still conscious and walking around.
The pulmonary veins are high in oxygen and low in carbon dioxide. All other veins are high in carbon dioxide and low in oxygen.
Depends how low. I have low oxygenation, and I am doing --- argh. Just kidding about the "argh". If the oxygen level gets low, you go to sleep (before you die). OH, by the way, I dumped my treatment when I found out the "system" was incrediably stupid. It wouldn't give me drugs to go out of state, and I was going. I didn't die out of state, and I now ignore the treatment. OK, I'm lucky. Figure out if you are lucky before you dump your drugs. I hope you are correct.
there is no such thing because we breath oxygen and breath out carbon dioxide
hypoxemia
Anemia is caused by low iron and low blood levels. The iron in your blood allows oxygen to bind to your red blood cells to transport it to the cells of your body. If you are lacking iron and red blood cells, your body has less transporters to take oxygen to your cells, including your brain cells. This can cause you to feel dizzy because your brain isn't getting as much oxygen as it needs to be. If you are anemic and feeling dizzy, please see your doctor. Your oxygen levels could be low and you may need to start a treatment regimen to raise your iron and blood levels.
