Sexual reproduction is vital to the propagation of the Human race. Which of the following sequences represents the correct order of events in the formation of a human fetus?

• Zygote → Blastocyst → Embryo → Fertilization

• Fertilization → Zygote → Blastocyst → Embryo

• Blastocyst → Embryo → Differentiation → Zygote

• Fertilization → Growth → Differentiation → Zygote

In which of the following structures of the female human reproductive system is the blastocyst implanted during normal human development?

• Ovary

• uterus

• vagina

The diagram below represents structures found in the female reproductive system. If the areas labeled A were completely blocked on both sides, the most likely result would be that

• egg production would stop

• sperm production would stop

• fertilization would not occur

• an embryo would develop
