Question

Quizplus · Accepted Answer

Carole is correct. The fertilized egg cell is initially nourished by the nutrients within the yolk of the ovum. As it travels down the fallopian tube, it undergoes cell division and gains mass. It then implants into the uterine lining, where it can continue to receive nourishment from the mother's bloodstream.
