The logic behind polar body biopsy is based on:
a. darwin's theory of natural selection.
b. mendel's law of segregation.
c. mendel's law of independent assortment.
d. the rules of the central dogma.
e. the idea that the alleles in a polar body are the same as those in the oocyte to which it was attached.

e. the idea that the alleles in a polar body are the same as those in the oocyte to which it was attached.

Explanation:

Meiosis I in primary oocyte forms a secondary oocyte and a polar body. The secondary oocyte undergoes meiosis II and forms an ovum (egg cell) and a polar body.  

Since polar body and ovum/secondary oocyte are derived from the same precursor cell, they share common alleles. Hence, a biopsy of polar bodies helps to diagnose any possible genetic defects in the embryo during genetic screening.  

well, you see. the answer to your question is quite simple. the thing that is big, powerful, and over 9,000 is your mom.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
