6. Describe about fertilization and implantation.

Fertilization happens when a sperm cell combines with an egg cell, resulting in a zygote containing a full set of genetic material. This typically occurs in the fallopian tube post-ovulation. The zygote then goes through rapid cell divisions to become a blastocyst. Implantation, occurring roughly 6-10 days after fertilization, involves the blastocyst adhering to the uterine lining. This process allows for nutrient exchange between the mother and the growing embryo. Hormonal shifts support the uterine lining's readiness for successful implantation. If it's successful, the embryo continues developing. If not, the absence of implantation leads to menstruation.
