Answer 1

The correct sequence of prenatal stages of development is germinal stage, embryonic stage, fetal stage.

Step-by-step explanation:

The correct sequence of prenatal stages of development is in the order of:

1. Germinal stage: This stage lasts for the first two weeks after fertilization and involves the early cell divisions and developmental stages of the zygote, morula, and blastocyst.
2. Embryonic stage: This stage starts at implantation and lasts until the eighth week after fertilization. It is characterized by significant growth and changes in the developing embryo, including the formation of body and organ structures.
3. Fetal stage: This stage begins at 9 weeks and lasts until birth. It involves rapid growth and development of the body, brain, and organs.
