Question

which is a symptom that is common in people with sickle cell disease?
mood disturbances
fragile bones
stooped posture
frequent infections

Explanation:

Sickle cell disease affects the immune system and red blood cells. People with this disease have a higher risk of frequent infections because the abnormal red blood cells can impair the immune response and the spleen (which helps fight infections) may be damaged or not function properly. Mood disturbances, fragile bones, and stooped posture are not typical common symptoms of sickle cell disease.

Answer:

D. frequent infections
