People with type AB blood have A and B antigenes on the surface of red blood cells (RBCs). Antigen AB has no antibodies, thus, transfusion can be considered safe ( the serum of the recipient does not contain antibodies for the blood cell antigens of the donor).

1. How does the inner core affect all of the Earth's other layers?

Artist 52 [7]

Answer:

With the heavy inner core, the earth's orbit and rotation will remain stable over the long term, giving us day and night and summer and winter. ... These swirling convection currents result in the earth's magnetic field which keeps us properly oriented for travel, and shields earth from deadly cosmic rays

Explanation:

The inner core is the fourth layer inside the Earth. It is a solid metallic ball made mainly of iron. Here, temperatures reach extraordinary levels, estimated to be between 7,200–8,500ºF (4,000–4,700ºC). Although the inner core is very hot, it is not liquid like the outer core.
