The answer is; saturated soil turns into liquid that can't support buildings
Soil liquefaction occurs mainly in soils saturated, or partially saturated, with water such as in wetlands. During an earthquake, the waves pass through the soil and make it behave like a wave in a fluid. This causes the soil to loosen temporarily and become weak. The foundation of buildings in the soil fail and the structures collapse.
Frederick Miescher first identified DNA.
DNA provides the instructions for protein production.

The prenatal is the stage of the development of the foetus from the fertilized cells towards the whole organism. In the embryo stage, the cells divide and the organs are formed.
<h3>What are the stages of prenatal division?</h3>
In the embryo stage of the foetus development the formation of the cells and their division occurs, it is the early stage of the development where the multicellular diploid organism results in the formation of the distinct organs with specialized functions.
Blastocysts are the early group of cells formed after zygote formation and is important for the implantation in the uterus lining.
A zygote is the immediate result of egg and sperm fusion. This cell is the earliest cell that is diploid and is formed just after fertilization.
Therefore, option A. embryo is the stage in which the formation of the organs occurs.
