Question

the spindles disappear in what phase of mitosis? prophase anaphase final phase

Explanation:

Mitosis has several phases. Prophase is when spindles form. Anaphase is when sister chromatids separate. The final phase (telophase) is when spindles disappear as the nuclear envelope reforms and chromosomes decondense.

Answer:

Final phase (Telophase, though labeled as Final phase here) is when spindles disappear. So the answer is Final phase.
