You look through a microscope, and see a cell with the following characteristics. What phase of the cell cycle is this cell in? the chromosomes are shaped like lines (not X's) the chromosomes are divided at each end of the cell the nuclear membrane is starting to reform

Telophase

Explanation:

Each sub-phase of M-phase can be distinguished and identified very easily now as each sub-phase shows certain characteristics features.

In the given question, the chromosomes are divided at the end that is they have been distributed to the poles of the cells, appear shaped liked lines and the nuclear envelope starts to appear around them as well as the nucleolus.

This sub-phase of the M-phase is known as the "Telophase". Cells during Telophase are characterized by having nuclear membrane formation and other characteristics mentioned in the cells support that the cell is in Telophase.

Thus, Telophase is correct.
