Cold temperature and higher pH cause the oxygen-hemoglobin saturation curve to shift high reflecting that hemoglobin releases more oxygen.
Explanation:
In higher pH i. e. neutral or alkaline and low body temperature, the hemoglobin molecule attach more oxygen to their active sites. When the temperature of the blood increases, the hemoglobin stops or reduces the binding of oxygen to their active sites and lower the saturation level. Oxygen-hemoglobin saturation level refers to the amount of oxygen binds with the hemoglobin. This saturation decreases with increase in temperature and lower pH while saturation level increases when the temperature of the body is lower and pH is high.
In situations of cold and inactivity, hemoglobin with oxygen has less affinity, therefore it means that it releases oxygen more easily.
In this way the curve moves in a higher way.
Explanation:
The pH also affects since hemoglobin being a protein is influenced by the acidity or alkalinity of the medium to determine the forms of its active site and therefore this determines the affinity with different gases, one of them is oxygen.
★ Cnidarians have groups of similar cells that work together as tissues, while sponges have no tissues, only disconnected regions of specialized cells.
In 1884, Hans Christian Gram described a method of staining bacterial cells while not staining surrounding animal tissues. However, he thought that the staining method he developed was faulty because not all bacteria stained. ... Not all bacteria stained because some have walls that prevents the staining.
