Two sister chromatids are held together by the centromere
<h3>The Chromosome</h3>
The chromosome consists of 2 sister chromatids that are linked together by a structure known as the centromere.
Each of the sister chromatids carries an allele of the same gene.
The link between the two sister chromatids is broken at the anaphase stage of the cell division when spindle fibers pull them apart towards opposite poles within the cell.

Answer:B
Explanation:because mercury has a very thin atmosphere.
Insects that go through three stages of change in their life cycle have an incomplete metamorphosis while complete metamorphosis has four stages. The first stage of incomplete metamorphosis is the egg. During this time, the insect will hatch into a form called a nymph.
In meiosis one, homologous chromosomes only separate resulting in two cells. In meiosis II, the cells divide further, separating sister chromatids and resulting in four cells. So the cells are just even smaller with less chromosomes in each one.
