What is the part of the blastocyst that promotes implantation and produces hCG?
The trophoblast is the part of the blastocyst that promotes implantation and produces human chorionic gonadotropin (hCG). This hormone helps maintain the uterine lining during early pregnancy and is the basis for most pregnancy tests.
What happens to the blastocyst cells that do not become a human body?
The blastocyst cells that do not become part of the human body form the placenta and other supporting tissues necessary for fetal development. These cells contribute to the formation of structures that facilitate the exchange of nutrients and waste between the mother and the developing embryo.
What is the name for the group of the approximately 100 cells that forms from a fertilized egg?
The group of approximately 100 cells that forms from a fertilized egg is called a blastocyst. It is the stage of development that precedes implantation in the uterus during early embryonic development.
What part of a blastocyst will eventually undergo gastrulation and form the embryo?
The inner cell mass of the blastocyst will undergo gastrulation and form the embryo. This inner cell mass consists of pluripotent cells that will give rise to the various tissues and organs of the developing embryo.
Attachment of the embryo to the wall of the uterus?
"When pregnancy occurs, the endometrium is the site of attachement of the embryo and forms the maternal part of the placenta from which the fetus is nourished."got this from Saladin textbook 5th edition, Anatomy and Physiology: The Unity of Form and Function (page 1083)

What is a placenta formed from?
The placenta is developed during pregnancy from the implantation of a blastocyst. The blastocyst creates the outer layer of the placenta. This continues to developed into two more portions and then develops an outer protective layer. The placenta grows throughout the entire pregnancy.
What is the mass of stem cells produced in the first few days after ferlization?
blastocyst The most versatile stem cells occur earliest in life. As a fertilized human egg divides, it first becomes a solid ball of cells, the morula. Next, about five days after fertilization, it becomes a hollow ball, the blastocyst. The cells of the outer layer of the blastocyst eventually form part of the placenta.

The part of the uterus that will become the maternal portion of the placenta?
The decidua basalis portion of the endometrium

Does the blastocyst develop after feritilzation?
Yes. It is part of the development of the embryo.
What part of the uterus does the placenta attached to?
The placenta will be attached to the uterus, but it is not part of it. The uterus is a muscle and is part of basic female human anatomy. The placenta is an organ which is formed after conception.
Do tuna have placenta?
No, tuna fish do not have placentas. The placenta is part of mammal physiology, and fish are not mammals.
What is the term used for new human life after fertilization?
embryo You go from ovum (egg) + sperm and get a zygote. A single fertilized cell. This divides rapidly forming a blastocyst. The blastocyst has a few parts even though it is a tiny ball of cells. One part will eventually form the placenta and the other part, called the embroblast. At this point the baby-to-be has not implanted, that is, it has not reached the uterine cell wall to initiate pregnancy. The cell could easily die on it's own at this stage, the mother-to-be is not considered pregnant either. Her body is not yet hosting or contributing anything to the growth of the blastocyst. When the blastocyst implants it will grow a placenta that gets nutrients from the (now pregnant) mother and uses her blood stream to eliminate waste. Now we have an embryo. The term embryo can be used to describe this whole period from first fertilization to eight weeks of pregnancy. But, the moment of implantation is just so important to the whole process that I think the distinction should be made. After eight weeks of pregnancy you have a fetus and after birth you will have an infant/newborn/baby. Hope this helps, D
What is the part of the fruit that encloses the seed?
Fruit placenta
