Question

a person with type o blood has anti-a antibodiesb antigensanti-b antibodiesboth anti-a antibodies and anti-b antibodieswhich clotting disorder is an inherited x-linked disorder? thrombosisthrombocytopeniahemophiliaembolismthe pulmonary semilunar valve is the valve *between the left atrium and left ventriclethat opens from the right ventricle into the arterybetween the right atrium and right ventriclethat opens from the left ventricle into the artery

Explanation:

1. For blood type O: Type O blood has no A or B antigens on red blood cells, so the plasma contains both antibodies against A and B antigens to react with foreign blood cells.
2. For clotting disorder: Hemophilia is caused by mutations in genes on the X chromosome, making it an X-linked inherited bleeding disorder; other options are not X-linked inherited conditions.
3. For pulmonary semilunar valve: This valve separates the right ventricle and the pulmonary artery, opening to allow blood from the right ventricle into the pulmonary artery (the artery carrying deoxygenated blood to the lungs).

Answer:

1. both anti-A antibodies and anti-B antibodies
2. hemophilia
3. that opens from the right ventricle into the artery
