Body waves are two types: compressional or primary (P) waves and shear or secondary (S) waves. P- and S- waves are called “body waves” because they can travel through the interior of a body such as Earth’s inner layers, from the focus of an earthquake to distant points on the surface.
Answer:
mass : volume
Explanation:
Density is a physical quantity. An intensive property which can be used to determine any substance in nature.
Density is a unique quantity because it highlights the mass per unit volume of a substance.
Mathematically;
Density = ![\frac{mass}{volume}](https://tex.z-dn.net/?f=%5Cfrac%7Bmass%7D%7Bvolume%7D)
Mass is the amount of matter contained in any substance
Volume is the space they occupy
We clearly see that the ratio of mass to volume gives the value of density.
Answer:
Amount of food, competition with other species, habitat space
Theories may change over time. Unversal laws are supposed to not change.
Most theories and laws cannot not be definetly proved and they are constantly tested.
Consensus is not necessary. Many theories were discarded by the majority of scientific community before been accepted.
Both theories and laws must be based on scientific method and observations are a key part of it. Then, in my opinion, the true statement is that both are supported by observartios.
In an animal cell, DNA is found in the greatest concentration in the Nucleus.
