Q)

The embryo with 8 to 16 blastomeres is called a _________________ (e), which continues to divide and transforms into __________________ (g) as it moves further into the uterus. The blastomeres are arranged into an outer layer called _________________ (J) and an inner group of cells attached to trophoblast called the __________________ (I). What is (h) and what does it imply?

( a ) morula, blastocyst; syncytiotrophoblast, inner cell mass; Implantation -The trophoblast layer then gets attached to the endometrium and the inner cell mass gets differentiated as the embryo. After attachment, the uterine cells divide rapidly and covers the blastocyst which becomes embedded in the endometrium of the uterus. Implication - It leads to pregnancy.
( b ) blastocyst, morula; trophoblast, inner cell mass; Implantation - The trophoblast layer then gets attached to the myometrium and the inner cell mass gets differentiated as the embryo. After attachment, the uterine cells divide rapidly and covers the blastocyst which becomes embedded in the myometrium of the uterus. Implication - It leads to pregnancy.
( c ) morula, blastocyst; syncytiotrophoblast, inner cell mass; Implantation -The trophoblast layer then gets attached to the myometrium and the inner cell mass gets differentiated as the embryo. After attachment, the uterine cells divide rapidly and covers the blastocyst which becomes embedded in the myometrium of the uterus. Implication - It leads to pregnancy.
( d ) morula, blastocyst; trophoblast, inner cell mass; Implantation -The trophoblast layer then gets attached to the endometrium and the inner cell mass gets differentiated as the embryo. After attachment, the uterine cells divide rapidly and covers the blastocyst which becomes embedded in the endometrium of the uterus. Implication - It leads to pregnancy.
