Most of what we know about the interior of the Earth comes from the study of seismic waves from earthquakes Primary waves waves) are compressional waves that are longitudinal in nature while secondary waves (S-waves) are shear waves that are transverse
waves. The graph shows the velocity of both waves as they pass through Earth's interior. What do these two waves have in common
regarding velocity?

same speed because as you can see when they inyer in to a medium there speed increase in same

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
