d. To promote healthy growth, a fertilized egg must attach itself to the uterine wall.
Correct Answer:
The answer is option d, To promote healthy growth, a fertilized egg must attach itself to the uterine wall.
Reasoning:
The development of the fetus initiates with conception and implantation. Conception refers to the meeting of the male sperm with the female egg cell for fertilization. Following fertilization, the egg must implant in the uterus of the woman. After it adheres, the fertilized egg cell (embryo) becomes recognized as a "blastocyst." This phase is crucial for fetal growth as it ensures the embryo receives essential nutrients from the mother.
Implantation typically takes place between 6 and 9 days post-fertilization. Symptoms a woman may experience include: fatigue, breast sensitivity, frequent urination, cravings, nausea, mood fluctuations, headaches, etc.
