Chorionic villi sampling (cvs) is a test to determine whether fetal cells have genetic abnormalities and can be performed as early as 8 weeks. chorionic villi cells are removed using a small tube that is passed through the cervix. these cells are cultured and undergo chromosomal analysis.
explain why chorionic villi cells will determine whether the fetus has genetic abnormalities.

The zygote is formed by the fusion of the male and female gamete during the process of sexual reproduction. Chorionic villi sampling (CVS) is used to determine the sex of the baby and genetic abnormalities.

The fetal cells and chorionic villi has the same genome. The villib are derved from the cells known as trophoblast that are known to form the blastocyst outer layer. This provide nutrition to the embryo through the placenta. These cells first differentiate from the egg and shares the same genetic makeup. Any abnormalities in these  cells shows the genetic abnormalites.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest

human didn't come from monkeys man i hate these stupid teachers
