The
peripheral nervous system (PNS) consists of nerves that transmit impulses back
and forth between the central nervous system, the skeletal muscles, and the
skin.
<span>The
PNS consists of the nerves and ganglia that are located outside the brain and

Answer:
A. Antibodies to A and B are present in the red cells.
Explanation:
AB positive is a blood type with the presence of A and B antibodies in the red blood cells, with the absence of A and B antigens. This blood type is referred to as the “universal recipient” because individuals who are AB positive can receive from all blood types including O, A and B.

Explanation:
This much is undeniable. Based on the magnetic fingerprints locked into ancient rocks, we know that over the last 20 million years, magnetic north and south have flipped roughly every 200,000 to 300,000 years (this rate has not been constant over the planet's lifetime, though).
This could weaken Earth's protective magnetic field by up to 90% during a polar flip. Earth's magnetic field is what shields us from harmful space radiation which can damage cells, cause cancer, and fry electronic circuits and electrical grids.
