carbon dioxide

It reacts very readily with oxygen by burning smokelessly, with carbon dioxide and water as its byproducts.

Other psychiatrists attempted to treat schizophrenia with carbon dioxide gas and artificially-induced comas.

The higher levels of carbon dioxide will induce something of a feeding frenzy for plants, at least for a while.

“We are short of carbon dioxide for the needs of the plants,” Anderson said.

First they smell us, detecting molecules from bacteria on our skin and carbon dioxide from our breath.

The primary purpose of respiration in all animals is the same—namely, to furnish oxygen and remove carbon dioxide (carbonic acid).

If we collect enough of these bubbles of gas to make a test, we find it to be carbon dioxide.

In previous experiments we have proved that carbon dioxide is given off by any living thing when oxidation occurs in the body.

The plants give off oxygen to the animals, and the animals give carbon dioxide to the plants.

The organs of respiration: the organs in which the blood receives oxygen and gives up carbon dioxide.
