Fill in the blanks to complete the passage. Geologists can use ________ waves to learn about Earth’s interior. P waves travel fa
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.

Based on the information in the graph, which blood type is most likely to be in shortest supply during an emergency?
Maksim231197 [3]
While there is no graph provided and I cannot find the graph online, I will base my answer through theory. 

In theory, the most common blood type is O+, followed by A+, then B+, then AB+. Rh negative blood is deemed to be rare. While the most common blood type is O+, the same blood type is also called the "universal donor" as a type O+ blood has no antigens attached in red blood cells therefore the probability of adverse reactions (i.e. hemolytic reactions) when transfused to other blood types are close to nil. In an emergency situation, wherein there is not enough time to do proper crossmatching, blood type O+ can be used therefore supplies of blood type O+ are easily depleted.
