Quizplus · Accepted Answer

A blastocyst is an early stage of development in pregnancy, where a ball of identical cells has formed but has not yet differentiated into recognizable body parts. The blastocyst typically implants in the uterine wall around five or six days after fertilization. Embryo (A) refers to a later stage of development, after the blastocyst has begun to differentiate into specific cell types. Fetus (C) refers to a later stage of development still, after all major organs and body systems have formed. Neonate (D) refers to a newborn baby up to four weeks old.
