The spindle apparatus disintegrates during anaphase telophase interphase metaphase

Answer;

-Telophase

Explanation;

-The spindle apparatus disintegrates during the telophase of mitosis. Telophase is the final stage of mitosis.

-During this phase, the sister chromatids reach opposite poles. The small nuclear vesicles in the cell begin to re-form around the group of chromosomes at each end.

-As the nuclear envelope re-forms by associating with the chromosomes, two nuclei are created in the one cell. Telophase is also marked by the dissolution of the kinetochore microtubules and the continued elongation of the polar microtubules.

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.
