Answer 1

Answer: RATE ME PLEASE AND GIVE ME A THANKS

Explanation:

The blastocyst is a structure formed in the early development of mammals. It possesses an inner cell mass (ICM) which subsequently forms the embryo. The outer layer of the blastocyst consists of cells collectively called the trophoblast.The trophoblast gives rise to the placenta.

Answer 2

Answer:

The blastocyst is the ball of cells; it is the end result of the zygote separating into many, many cells during the first week of fertilization. The outer cells create a "shell" around the inner cells. The inner cells will eventually become an embryo. The outer cells will form the amniotic sack, umbilical cord, and the placenta after the blastocyst implants itself in the uterus in 10 days.
