Trophoblast
Correct Answer
A. BlastocystExplanation
After fertilization, the zygote undergoes several divisions and forms a hollow fluid-filled ball called a blastocyst. The blastocyst is an early stage of development in embryos of mammals, including humans. It consists of an outer layer of cells called the trophoblast, which later develops into the placenta, and an inner mass of cells called the embryoblast, which develops into the embryo itself. The blastocyst is an important stage in embryonic development as it marks the beginning of implantation into the uterine wall.Rate this question:

-
- 29.
Fertilization usually takes place in the fallopian tubes
-
True
-
False
Correct Answer
A. TrueExplanation
Fertilization usually takes place in the fallopian tubes because this is where the sperm and egg meet. After sexual intercourse, the sperm travels through the cervix and into the uterus, then into the fallopian tubes. If an egg is present in the fallopian tube, it can be fertilized by the sperm. The fertilized egg then travels down the fallopian tube to the uterus for implantation and pregnancy to occur. Therefore, it is true that fertilization usually takes place in the fallopian tubes.Rate this question:
-

As many as 50 % of the zygotes do not survive the first two weeks
-
True
-
False
Correct Answer
A. FalseExplanation
The statement claims that 50% of zygotes do not survive the first two weeks, but this is incorrect. Zygotes are the fertilized eggs that develop into embryos, and it is estimated that a significant percentage of zygotes do not successfully implant in the uterus and therefore do not develop further. However, it is not accurate to say that 50% of zygotes do not survive the first two weeks, as the actual percentage may vary and is not specified in the statement. Therefore, the correct answer is False.Rate this question:
