Question

how does interphase relate to mitosis?
interphase is unnecessary for mitosis.
interphase reverses the results of mitosis.
interphase happens concurrently with mitosis.
interphase alternates with mitosis.
interphase is one phase of mitosis.

Explanation:

The cell cycle consists of interphase (where the cell grows and prepares for division) and mitosis (where the cell divides). They alternate in the cycle. Interphase is necessary for mitosis (so "Interphase is unnecessary for mitosis" is wrong). Interphase does not reverse mitosis results (so "Interphase reverses the results of mitosis" is wrong). Interphase and mitosis are sequential, not concurrent (so "Interphase happens concurrently with mitosis" is wrong). Interphase is not a phase of mitosis (mitosis has prophase, metaphase, anaphase, telophase), so "Interphase is one phase of mitosis" is wrong.

Answer:

Interphase alternates with mitosis.
