It was cos high blood sugar concentration means less water in the blood so it was hypotonic to the cell, so water osmoses out of the cell and into the bloodstream

monoclonal antibodies can block receptors of cancer cells and stop it dividing and spreading, and it can have toxic/radioactive substances attached so it can kill the cancer cell directly, and it can attach to the antigens of the cancer cell and stimulate white blood cells to engulf it
(Original post by Erevising45)
What did everyone put for the monoclonal antibody question? I think I put something about how antibodies bind to molecules in the blood so they can be detected and destroyed.
