Because it is a "transplant" that can include apcs and t cells from the donor, a bone marrow transplant may induce a very specific type of rejection known as disease.

A bone marrow transplant may result in a very specific type of rejection called the Graft-versus-host disease

Explanation:

The Graft-versus-host disease is a complicated immune condition which arises after a transplantation procedure. This condition arises when the immune cells of the donor, present in the transplanted tissue or organ, does not recognize and thus rejects and attacks the host tissues of the recipient. Therefore, leading to Graft-versus-host disease.

This disease is a common side effect after an allogeneic bone marrow transplant.

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
