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. <em>Conception</em><u> is the process by which the male's sperm meets with the woman's egg cell in order to be fertilize</u>d. 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<em> "blastocyst."</em> 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:<em> fatigue, breast tenderness, increased urination, food cravings, morning sickness, mood swings, headaches, etc.</em>
