Answer:
d. Hemoglobin helps maintain a constant pH in the blood by binding with H⁺ions released from bicarbonate ions.
Explanation:
The presence (CO₂) in in the erythrocytes lowers its pH as a result the affinity of hemoglobin decreases for oxygen. The carbon dioxide (CO₂) reacts with water to form carbonic acid in the presence of the enzyme carbonic anhydrase which is present in the erythrocytes or red blood cells. The carbonic acid then changes into two ions hydrogen ion (H⁺) and bicarbonate ion (HCO₃⁻). As a result of H⁺ ions, the pH of blood drops. Haemoglobin pick up hydrogen ions to balance the decrease in pH. Thus, haemoglobin helps in maintaining constant pH or keep pH of blood in buffer.
Answer:
Acclimatization
Explanation:
Acclimatization is the change in the body of an organism in response to changes in the environment to maintain equilibrium (homeostasis). In the case of the salmon, when the environment changes from fresh to salt water and back, the chemical homeostasis would be altered if the fish didn't adjust. The adjustments in the fish gills are the response of the fish to acclimatize to the changes in the chemical environment in order to maintain homeostasis.
