Question

during the middle of mitosis, how many nuclear envelopes does the cell have? 0 1 2 3

Explanation:

During mitosis, specifically in prophase, the nuclear envelope breaks down. It remains broken down until telophase when new nuclear envelopes form around the separated sets of chromosomes. Since the question asks about the middle of mitosis (which would be metaphase or anaphase), the nuclear envelope is still broken down.
