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.

Answer:
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen, are replaced by stronger bonds in the products. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions.
Answer:
En la fotosíntesis, la energía de la luz se utiliza para convertir el dióxido de carbono y el agua en glucosa y oxígeno. Para 6 moléculas de dióxido de carbono y 6 de agua, se producen 1 molécula de glucosa y 6 moléculas de oxígeno.
Explanation:
Because we learn over time how things work and how they don't work.
