Vedclass · Answer

(A) In the process of development,the morula continues to divide and transforms into a blastocyst. As the blastocyst forms,the cells arrange themselves into an outer layer called the trophoblast and an inner group of cells called the inner cell mass. The blastocyst also contains a fluid-filled cavity known as the blastocoel. During this stage,the zona pellucida begins to degenerate or break,allowing the blastocyst to implant in the uterine wall. Based on the provided figure: $A$ points to the breaking zona pellucida. $B$ points to the inner cell mass. $C$ points to the blastocoel (cavity). $D$ points to the outer layer of cells,the trophoblast.
