Explanation:Hope you get it right
Answer:
The statement C that says ''is derived from the inner cell mass'' is false.
Explanation:
The trophoblast is a structure composed of a set of cells (cytotrophoblast and syncytiotrophoblast), which are shaping the outer layer surrounding a blastocyst, during the earliest stages of embryonic development that mammals pass.
The trophoblast provides nutritive molecules to the developing embryo and facilitates its implantation to the uterine wall due to its ability to erode the tissues of the uterus, that is, it is responsible for making it possible for the embryo to be implanted in the uterine endometrium. Thus, the blast can join the cavity formed by the uterine wall, where it will absorb nutrients from the fluid from the mother.
During the third week, embryonic development includes the development of the trophoblast. At the beginning, the primary villi are formed by the internal cytotrophoblast which is surrounded by the outer layer of syncytiotrophoblast. Then, the cells found in the embryonic mesoderm are directed to the primary villous in the third week of gestation and when it ends, the mesodermal cells begin to be singled out to form blood vessel cells.

Cassini was the name of the satellite.
Eukaryotes.
There are two main division of organisms in the wide spectrum of species. Eukaryotic organisms and prokaryotic organisms.
These organisms is divided based on the cell number they have. Further, eukaryotes have a dynamic function and strata in terms of cell structure and I'm not discussing in its internal parts but the external varieties invovled.
Eukaryotes are unison of different cells that function specifically however, interdependent of one another. That is why they are called cells, and group of cells are called tissues and so on.
