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.
The exception to this rule is type O blood. It only has H antigens, which are present in the other blood types too. To a person with type A or type B, it seems familiar. That familiarity makes people with type O blood universal donors, and their blood especially valuable to blood centres.
