Final answer:
Chromosomes uncoil during telophase, which is true; however, mitosis is complete when cell division has occurred is false, as mitosis ends at telophase and is followed by cytokinesis for actual cell division. The reappearance of the nuclear membrane during mitosis is true, marking the end of mitosis with the formation of two daughter nuclei.
Step-by-step explanation:
The statement chromosomes uncoil during the completion of mitosis is True. As mitosis reaches the terminal phase known as telophase, the chromosomes that were previously condensed and separated reach the opposite poles of the cell and begin to uncoil, transitioning into a more relaxed chromatin state. This process facilitates the beginning of the next cell cycle where the DNA must be in a form that allows for gene expression and DNA replication.
Also, mitosis is complete when cell division has occurred is a False statement. Mitosis technically concludes at the end of telophase with the reformation of the nuclear membranes around the decondensed chromatin and the initiation of the nucleoli within the new nuclei. However, cell division is finalized only after cytokinesis, which is the process following mitosis that divides the cytoplasm and cell membrane resulting in two separate daughter cells.
Finally, the statement that the reappearance of the nuclear membrane is part of the mitotic process is True. The reformation of the nuclear envelope during telophase encases each set of chromosomes, allowing the two daughter cells to restore their normal nuclear functions post-mitosis.
