A) Fertilization- the fusion of Male and female gamete to form a zygote B) Implantation- the adherence of a feretilized egg to the uterine wall C) Gastrulation- the reorganization of cells I to layer changing the embryo from a single ball of cell into multi-layered organism D) None of the above
C) Gastrulation- the reorganization of cells I to layer changing the embryo from a single ball of cell into multi-layered organism
Explanation:
We can say that the figure above represents gastrulation, because we can see the creation of the three germ layers, which only occur in this phenomenon.
Gastronomy is characterized by the invagination of embryonic tissues that contain three germ layers, endoderm, mesoderm and ectoderm. In the figure above, each of these layers is represented by different colors to emphasize the visualization.
