Question

how does the shape and function of red blood cells differ in people with sickle cell disease compared healthy individuals?
○ rigid crescent shape; carries more oxygen
○ rigid round shape; carries less oxygen
○ flexible crescent shape; carries less oxygen
○ flexible round shape; carries more oxygen
○ rigid crescent shape; carries less oxygen

Explanation:

Sickle cell disease causes red blood cells to become rigid (due to abnormal hemoglobin) and crescent - shaped (sickle - like). This abnormal shape impairs their ability to carry oxygen effectively compared to healthy, flexible, round - shaped red blood cells.

Answer:

rigid crescent shape; carries less oxygen
