Answer:
Anaphase
Explanation:
<em>The centromere splits during the anaphase of the cell division. Thus, allowing the two linked chromatids to separate.</em>
A typical chromosome is made up of two sister chromatids joined together by a structure known as the centromere. During cell division - at the metaphase stage - the chromosomes align at the equator of the cell, forming the metaphase plate. The spindle from the opposing ends of the cell engages each chromosome at the kinetochore of the centromere.
<u>At the anaphase stage</u><u>, the centromere splits, leading to the separation of the sister chromatids of each chromosome. The sister chromatids of the same then start migrating in the opposite direction as a result of the shortening of the spindle fiber.</u>
Answer: covalent bonds
Explanation: Two covalent bonds form between the two oxygen atoms because oxygen requires two shared electrons to fill its outermost shell.
The electron configuration of an atom can be determined by identifying first the right order of the electron shells. The atomic number of Magnesium is 12 so we expect the electrons also sum up to 12. The condensed electron configuration is Ne 3s2. The complete configuration is 1s2 2s2 2p6 3s2.
