After four divisions, the zygote becomes a morula- the stadium that consists of 16 blastomeres. By the fifth day of development the form of the blastocyst is formed through the processes of compaction, cell division, and blastulation. Later, specialized cells in the embryo are derived from the inner cell mass (ICM) of the blastocyst.
<span>decomposition reaction occurs when the bonds of the reacting compounds are broken and new combinations are formed. A</span> compound partitions into its components.
