A and B are antigens that are on the surface of red blood cells. People have one, both, or none. If you don't naturally produce the antigen, your body's white blood cells will attack and destroy red blood cells that carry them.
So if a person with type A blood is injected with type B blood, the body of that person will attack the type-B blood cells.
O- is called the universal donor, because it lacks all antigens. So no one's body will recognize it as foreign. Because of this, hospitals often administer O- blood to patients with a critical need, because there isn't enough time to determine blood type of the patient.
Officially, there are 8 different types of blood but it is close since there are positive and negative versions of blood types A,B,AB, and O. But the least common type would be blood type AB-.
The least common blood cells are basophil granulocytes. These are referred to as basophils. Basophils make up 0.01 percent to 0.3 percent of white blood cells.
having sufficient magnification available.
ABO blood typing is a method for differentiating individuals' blood based on the presence or absence of two antigens, A and B. The most common blood type in the world is O positive, which has neither the A nor the B antigen.
They could, but they don't need to. Both of your parents must have at least one O allele, meaning neither can have type AB blood. They must be either BO, AO or OO to produce a child with type O blood.
The snowy owl and many other types of owls are endangered. Most owls are endangered except for a few. There are no species of endangered owl in North America. Below is the official status for NA owls, by species.

All info gathered from the IUCN Redlist.
