1 Bake the wings on a wire rack set inside a rimmed baking sheet. By baking the chicken wings on a wire rack, fat drips away from the wings while they bake and helps keep them crispy.  Bake chicken wings at a high temperature â we choose 400Âº F. The wings bake for 35 to 45 minutes.
O negative is the universal donor, in that you can give it to anybody and they won't have a reaction. AB positive is the universal recipient, in that they can have any type of blood given to them and will not have a reaction.
People with O- (read O negative) blood are referred to as universal donors. The red blood cells in O blood have no antigens, unlike all other blood types. The lack of antigens means people with other blood types won't react to O- blood, so O- blood is almost as good as receiving your own blood type. Only 7% of the population has 0- blood, which makes the universal donor somewhat rare.
