add example. 1  en The Amur Leopard (from the name of the river flowing at the border between Russia and China, or Far Eastern leopard, Panthera pardus orientalis) is quite certainly the rarest and most endangered big cat in the world because of a wild population of only 30 to 35 individuals [ 1 ].
Rebreathing resulted in acidosis because the pH value began to dip below the normal range between 20 and 30 secods--as soon as it went below 7.35. Acidosis is the result of impaired respiration (hypoventilation)that leads to the accumulation of too much carbon dioxide in the blood.
Changes in pH levels have the most noticeable effects on bacterial enzymes, reports Argonne National Laboratory. Extreme changes in the pH balance of the local environment for bacteria tend to kill them, but one common bacteria, Helicobacter Pylori, can handle highly acidic environments like the human stomach.
