Oxygenated blood is bright red. Deoxygenated blood is dark red. Oxygenated blood cells have a relaxed shape whereas deoxygenated blood cells have a tense shape. 2. Carbon dioxide concentration decreases as blood nears the lungs, which in return causes and increase in pH . Increased pH causes increased affinity for oxygen which causes the hemoglobin to pick up oxygen entering your blood to be transported to the body’s tissue. Hemoglobin loses hydrogen ions from specific amino acids at key sites as pH VIEW DOCUMENT

Established fish have their own territories and will protect them aggressively if the new fish may wander into that area. Usually the new fish will hide and go without food for several days trying to dodge these aggressors if possible. Depending on the animal, some will come out eventually, some will not. Animals die under the stress of the new enviroment coupled with postioning for rank and a place to establish as there own.
