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.
The correct ones are:
- Differential gene expression affects the developmental process in animals.
- Positional information controls pattern formation.
- Homeotic genes code for transcription factors that control the development of segment-specific body parts.
- Cells receive molecular signals that communicate their position in relation to other cells.
Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product, allowing it to produce end products such as protein or non-coding RNA and, as a result, affect a phenotype.
A homeotic gene is any of a group of genes that control the pattern of body formation in organisms during early embryonic development. These genes encode proteins known as transcription factors, which direct the formation of various body parts.
Molecular signaling refers to molecules that transmit information between cells in the body. However, the molecular properties of signaling molecules can vary greatly.

Answer:
Enzymes are proteins in composition which are a very essential component of the metabolic reactions in the living organisms.
The properties of enzymes allow the enzymes to be used as a reaction catalyst which increases the speed of the reaction.
The enzymes lower the threshold energy of the chemical reaction and thus increases the rate of reaction.
The enzyme catalyses very complex reactions like a breakdown of complex biomolecules as well as the formation of complex biomolecules.
The active sites are present on the enzymes which bind the substrate molecule and increases the pace of reaction.
