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.

Since plasma cells make your antibodies, they need to produce a lot of protein. Also because the nucleus makes a lot of products to make proteins you need a large Golgi Body. How ER's relate to this: to do protein synthesis you need ribosomes and to have ribosomes you need the rough ER!
Water exists as a solid at or below 0 degree Celsius.
At 0 degree Celsius, water can go through a phase change, either freezing or melting, depending whether energy is given or taken away. If the temperature is below 0, water should exist as solid as the temperature is lower than its melting point. If the temperature is right at 0 degree, the water can partially be solid and liquid at the same time, during phase change.
Therefore, water exists as solid at or below 0 degree Celsius.
