Answer 1

Sickle-cell anemia is a genetic blood disease caused by abnormally shaped hemoglobin protein in red blood cells. The deformed hemoglobin molecules can clog blood vessels and cause symptoms, such as muscle pains even at low levels of exertion.

Step-by-step explanation:

Sickle-cell anemia is a genetic blood disease caused by an abnormally shaped hemoglobin protein in red blood cells. This abnormal hemoglobin, called hemoglobin S, delivers less oxygen to tissues and causes red blood cells to assume a sickle or crescent shape, especially at low oxygen concentrations. The deformed hemoglobin molecules in sickle-cell disease can clog narrow blood vessels, obstructing blood flow and leading to a variety of symptoms, including muscle pains even at low levels of exertion.
