just olya [345]

Answer: Antigens

Explanation: The ABO system of blood grouping is based on the basis of the type of antigens that are present in the red blood cells. Erythrocytes is another name for the red blood cells. Antigens are molecules that are capable of eliciting immune response. There are two types of antigens: antigen A and B. Blood type A has only antigen A, blood type B has only antigen B, blood type AB has both antigen A and B while blood type O has no antigen (neither A nor B antigen).

Similarly, Rh trait is determined by the presence or absence of rhesus antigen in the erythrocytes. Rhesus antigen is an antigen first discovered in rhesus monkey. Rh+ indicates the presence of rhesus antigen in the red blood cells while Rh- indicates the absence of rhesus antigen in the red blood cells.

Kisachek [45]

Answer:

Seismic waves,    Outer,    Mantle

Explanation:

P-waves vibrate longitudinally to the direction of propagation while S-waves vibrate vertically to direction of propagation. This is why S-waves are called shear waves while P-waves are compressional waves. S-waves are the main cause of destruction in an earthquake and are slower than P-waves.

The wave movement of P-waves allows them to pass through liquids and gases while S-waves cannot. Due to this differential phenomenon of these waves, the reflection of P –waves and S-waves after an earthquake – and as their vibrations are picked up by seismographs around the earth - enabled scientists to determine the properties of the  layers of the earth’’s interior.
