In the prophase of mitosis if 18 duplicated chromosomes are in a cell then the number of chromosomes in interphase is <u>9</u>.
A cell's growth and division are accompanied by a sequence of processes known as a cell cycle. A cell spends the majority of its time in what is known as interphase, where it develops, duplicates its chromosomes, and gets ready to divide. The cell then exits interphase, goes through mitosis, and finishes dividing.
A sister chromatid is one that has two identical copies of a chromosome that are connected by a common centromere during chromosome DNA replication. In other words, a sister chromatid can also be thought of as "one-half" of a chromosome that has been duplicated. A dyad is a pair of sister chromatids.
Sister chromatids, which are firmly connected at the centromere region of each chromosome, are created as a result of DNA replication during the S phase (synthesis phase). Each chromosome is a duplicate at this point and is made up of two sister chromatids.

An oxidation-reduction<span> (</span>redox<span>) </span>reaction<span> is a type of chemical </span>reaction<span> that involves a transfer of electrons between two species. An </span>oxidation-reduction reaction<span> is any chemical </span>reaction<span> in which the </span>oxidation<span> number of a molecule, atom, or ion changes by gaining or losing an electron.</span>
<span>Mass is how much matter you are made of, so unless you eat a lot of junk food or somehow lose an arm on the way to the moon it will remain the same. Your weight is the combination of your mass and the pull of gravity and can vary greatly. Remember, the moon has about 1/6 the gravity of earth, so you'd weigh about 11.6 Kg on the moon.</span>
