Question

Quizplus · Accepted Answer

Fertilization occurs first, followed by the cortical reaction to prevent polyspermy. Mitosis then occurs in the fallopian tube, turning the zygote into a blastocyst. The blastocyst then implants in the uterus, completing the process of fertilization and implantation. The correct order is: 5, 4, 3, 2, 1.
