Sickle cell anemia is caused by a mutation on the eleventh chromosome. It replaces one amino acid with another. This swap of amino acids changes the structure of the red blood cell from a disk shape to a sickle, or curved, shape. The sickle-shaped red blood cells are less able to carry oxygen throughout the body. When organs do not receive oxygen from red blood cells, severe pain occurs.

Why do people commit suicide

Alona [7]

People commit suicide because of many reasons. It could include personal reasons, family issues, relationship problems, etc. These people feel they are in pain and that the world around them wouldn't care if they left. Most commonly, depression is a reason why they do commit suicide. They feel sad, lonely, and have no one to talk to.
