Question

organize stages of mitosis
spindle fibers pull chromatids apart
growth and loss of nuclear envelope
chromosomes line up in middle of cell
nuclear envelope develops over two new nuclei

Explanation:

Mitosis has several stages. First, the nuclear envelope breaks down and the cell grows (prophase). Then, chromosomes line - up in the middle of the cell (metaphase). After that, spindle fibers pull chromatids apart (anaphase). Finally, a nuclear envelope develops over two new nuclei (telophase).

Answer:

1. growth and loss of nuclear envelope
2. chromosomes line up in middle of cell
3. spindle fibers pull chromatids apart
4. nuclear envelope develops over two new nuclei
