What are the two types of evidence that scientists use to examine the inside of the earth?

The movement of seismic waves: p waves and s waves

Explanation:

seismic waves are produced by earthquakes as shock waves and can be detected by seismometers.

P waves travel through solid and liquid rock; they are longitudinal.

S waves travel though solid rock only and therefore are slower. They are transverse.

Looking at the speed of these waves with a seismometer You can identify which parts of the Earth are liquid or solid.

cell division has two checkpoints namely, g1

checkpoint and spindle assembly checkpoint. the checkpoint which determines if

division has properly occurred is the g1 checkpoint. at this point, is a damage

in the dna is detected or  the has not reach the optimum size, the cell is

stopped in g1 and is not allowed to proceed to further process.
