Question

1. if you were looking at a cell that had all of its chromosomes lined up down the middle of the cell, what phase must it be in? telophase prophase metaphase anaphase

Explanation:

Each stage of mitosis has distinct chromosome behavior:

• Prophase: Chromosomes condense, nuclear envelope breaks down.
• Metaphase: Chromosomes align at the cell's equatorial (middle) plane.
• Anaphase: Sister chromatids separate and move to opposite poles.
• Telophase: Chromosomes decondense, nuclear envelope reforms.

The described chromosome alignment matches metaphase.

Answer:

Metaphase
