Seismic waves travel in all the directions and used to determine the magnitude of an earthquake. There are 3 types of seismic waves that move in different directions.
1. P wave: It is the fastest of all three waves that travel through the interior of the earth and are compressive waves.
2. S wave: Secondary waves generally follow the P waves and travel through the interior of the earth but are shearing waves.
3. Surface wave: This is the slowest of all three waves that moves close to the surface of the ground.
These waves affect the movement of other materials when they are passing through the interior or surface of the earth.
P waves can move through the solid rocks and even liquids. S waves do not travel through the liquids such as water and molten magma. Surface waves causes shaking of the ground and do not go deep inside the earth.
The answer is: Because a subject might involuntarily manufacture a false memory and believe it is true.

Answer:
The correct answer is C eukaryotes have a greater variety of genetic material than prokaryotes.
Explanation:
Prokaryotic cells consist of single chromosome and their DNA is present in a dense region called nucleoid.As one copy of each gene is present in the chromosome prokaryotic cells are haploid.The DNA of prokaryotic cells are circular
Whereas eukaryotic DNA is linear and multiple distinct chromosomes are present in eukaryotes.Two copies of each chromosome are present are in many eukaryotic cells.As a result the eukaryotic cells are diploid in nature.
Due to this greater variety of genetic material the domain eukarya are more complex than archea and or bacteria domains.
Answer:
d.They are still very common ,but threatened with increasing harvesting for timber.
Explanation:
Brazil's Araucaria trees:
These trees are very soft and can be cut so easily.Brazilian pines is also know as Araucaria tree.
Before 1950's or 60's the number of trees were more but now due to harvesting the number of trees become less.The these trees are used for timber and for glue also.
In the present time the availability of these trees threatened with increasing harvesting for timber.
So the our option d is correct.

2. is the correct answer
