<u>STATEMENTS</u></h2>
The correct statement among the given answers is letter <u>d. an object in motion will remain in motion.</u>
<h2>
<u>WHY? </u></h2>
In reality, object that is in motion (like a ball) will remain in motion unless it's stopped by something (a wall or any force).
This is stated in the first law of motion by Sir Isaac Newton -- an object in motion will remain in motion unless an outside force acted upon the object.
During the S phase in the cell cycle, the chromosomes are replicated so that there are two copies. These copies are necessary so that each daughter cell created during the M phase will have an identical copy of the DNA.
Therefore, the answer is A: The DNA must be replicated.
The chromosomes joining, cell membrane expanding, and cytoplasm separating all happen during the M phase (mitosis).
DNA replication occurs in interphase, producing two sister chromatids
