At least one-quarter of the carbon dioxide (CO</span>2) released by burning coal, oil and gas doesn't stay in the air, but instead dissolves into the ocean.

Is there a cure for hemophilia A?
Molodets [167]

Answer: There is currently no cure for hemophilia.

Effective treatments do exist, but they are expensive and involve lifelong injections several times per week to prevent bleeding.The best way to treat hemophilia is to replace the missing blood clotting factor so that the blood can clot properly. This is typically done by injecting treatment products, called clotting factor concentrates, into a person's vein.
