The right answer is A. sismic waves.
Seismic waves correspond to elastic waves that propagate on the surface and inside our planet following an earthquake.
They appear when a starting impulse sets particles in motion, which in turn will move the material to their contact before returning to their original place. The generated phenomenon can then spread over tens, hundreds, even thousands of kilometers. Note that these waves can be generated artificially in seismic studies.
Like all waves, they can be reflected or refracted when they pass from one medium to another (for example between the mantle and the Earth's core).
Answer:

Explanation:
DNA polymerase can synthesize only a new DNA strand not m-RNA. It can do this in the 5’ to 3’ direction.
Answer:
The correct answer is - A wood-frame house built on bedrock.
Explanation:
An earthquake would damage a steel-frame building built on sediment in comparison of a wooden house built on the bedrock due to the fact that waves of an earthquake do not go through solid things easily such as the earth core or the bedrock land rather than reclaimed land or sediments.
So, the bedrock will shake less than the hotel or heave building built on sediment. A house that made up of wooden-frame would shake only whereas the steel-frame might damage more.
