Question

alexei romanov suffered from hemophilia, a condition that (1 point)
prevents blood from clotting normally due to the body’s inability to form fibrin proteins.
prevents the body from absorbing vitamin b12 due to the body’s inability to form fibrin proteins.
causes the body to produce too many blood cells due to the body’s inability to form fibrin proteins.
causes the body to produce abnormally shaped red blood cells due to the body’s inability to form fibrin proteins.

Explanation:

Hemophilia is a bleeding disorder characterized by impaired blood clotting. This is caused by a deficiency or dysfunction of clotting factors, which leads to the body's inability to form fibrin (a key protein in blood clot formation) properly. The other options describe unrelated conditions: vitamin B12 absorption issues relate to pernicious anemia, excess blood cells relate to polycythemia, and abnormal red blood cells relate to sickle cell anemia.

Answer:

prevents blood from clotting normally due to the body's inability to form fibrin proteins.
