Answer 1

1 Antibodies attack by binding to the foreign antigens on the surface of red blood cells. This is why Type O red blood cells (more specifically, O negative blood) can be donated to anyone, regardless of blood type, and is known as a 'universal donor'.

2 Normally, blood glucose levels increase after you eat a meal. When blood sugar rises, cells in the pancreas release insulin, causing the body to absorb glucose from the blood and lowering the blood sugar level to normal.
