Answer:
the number of electrons in it's outermost energy level
Explanation:
if the number of electrons in its outermost energy level is less than 4 that's the ion reacts by losing electrons and is thus the ion is positively charged
is the number of electrons in the outermost energy level is more than 48 react by gaining electrons and thus it is negatively charged
Answer:
In a diploid zygote, the cause of trisomy is two sister chromatids remain joined during meiosis II (option B).
Explanation:
At the end of meiosis I, each daughter cell contains a chromosome formed by sister chromatids, each of which must be separated in meiosis II to form the gametes with a chromosome charge equivalent to half the chromosome charge of the species.
The result of the sister chromatids not separating in meiosis II -by not disjunction- results in a gamete with an extra chromosome, which when joined to another gamete results in a zygote with an additional chromosome, which is considered an aneuploidy, called trisomy.
