d. To ensure proper growth, a fertilized egg must implant in the wall of the uterus.

Answer:

The answer is letter d, To ensure proper growth, a fertilized egg must implant in the wall of the uterus.

Explanation:

The fetal development process starts with the conception and implantation. Conception is the process by which the male's sperm meets with the woman's egg cell in order to be fertilized. Once the egg is fertilized, it has to be implanted in the woman's uterus. Once it adheres to the wall, the fertilized egg cell (embryo) now becomes known as a "blastocyst." This is a very essential stage for fetal development because this allows the embryo to receive proper nutrients from its mother.

Implantation occurs at least 6 to 9 days after the egg is fertilized. A woman may experience the following symptoms: fatigue, breast tenderness, increased urination, food cravings, morning sickness, mood swings, headaches, etc.
