The molecular and genetic basis of sickle cell anemia. Introduction: Sickle cell anemia is described as a condition, in which the RBCs (red blood cells) are shaped like sickles instead of a disc. These blood cells having a shape of a sickle get stuck in the blood vessels and block the flow of blood and also the distribution of oxygen to different body parts. This thus causes the most evident symptom of anemia, and also other symptoms like swelling of the abdominal region, pain in the bones and joints, vision problems, frequent infections, and delayed growth.

Normal dive (for diving humans) normal breathing dive normal breathing Oz level CO2 level urgent need to breathe Oz blackout zone high CO2 triggers breathing 6. This diagram shows rates of oxygen depletion and carbon dioxide accumulation in the blood in relation to the levels needed to maintain consciousness and trigger the urgent need to breathe in diving humans. How might the location and slope of the O₂ line differ for diving marine mammals such as whales and dolphins? • How might the location and slope of the CO₂ line differ for diving marine mammals such as whales and dolphins? • • Draw in predicted lines for O2 and CO2, based on your reasoning above. How might the location of the Urgent Need to Breathe line and the O2 Blackout Zone line differ for diving marine mammals? What physiological mechanisms account for each of these differences, resulting in the ability of marine mammals to stay submerged for long periods of time?
