Explanation / Answer

ANSWER 1
Animal development includes a series of consecutive stages. Please choose the answer that states the correct order of these stages:
C. Fertilization -> Cleavage -> Gastrulation -> Neurulation -> Organogenesis
Fertilization is the fusion of the two gametes hence first.
Cleavage is the process of the fertilized cell (zygote) multiplying to give a mass of cells.
Gastrulation is achieving the gastrula stage where a small cluster accumulates.
Neurulation is when the neural tube and plate is formed, this occurs pretty on in the developmental stage.
Organogenesis is the formation of the organs
