Ca2+ means that the charge on the ion is positive be two units. As electrons have a negative charge of -1, when an atom loses electrons, the overall charge increases. In F- one electron has been gained. Iron (III) is slightly different, it refers to the magnitude of the oxidation number rather than being a +3 charge

If the DNA content of a diploid cell in the G1 phase of the cell cycle is x, then the DNA content of the same cell at metaphase

REY [17]

Answer:

d. 2x.

Explanation:

At metaphase the DNA chromatides are duplicated. This explains that if in G1 phase of the cell cycle the DNA content is x, then the content in metaphase of meiosis I is 2x.
