At which stage would one be able to first distinguish a diploblastic embryo from a triploblastic embryo? a) fertilizationb) cleavagec) gastrulationd) organogenesise) metamorphosis

Gastrulation.

Explanation:

Zygote is formed by the fusion of the male and female gamete. The zygote undergoes the process of cleavage to form the different embryonic stages of the offspring.

Gastrulation is the important process of the pre embryonic development. The blastula get multiply and rearranged to form the gastrula. The gsatrulation process includes the formation of three germ layers also known as triploblastic embryo. The three germ layers are ectoderm, endoderm and mesoderm.

Thus, the correct answer is option (C).

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
