Question

the third phase of mitosis is called anaphase. what do you see happening in anaphase? select all that apply
the cell has divided
the chromosomes have split in half
the nucleus has dissolved
a new nucleus has formed on either end of the cell
the chromosomes are moving to either end of the cell

Explanation:

1. Analyze each option:

• "The cell has divided": Cell division occurs in cytokinesis, not anaphase. Eliminate.
• "The chromosomes have split in half": Chromosomes split at the centromere in anaphase, so sister chromatids (half of the chromosome structure) separate. This happens.
• "The nucleus has dissolved": The nucleus dissolves in prophase, not anaphase. Eliminate.
• "A new nucleus has formed on either end of the cell": New nuclei form in telophase. Eliminate.
• "The chromosomes are moving to either end of the cell": In anaphase, spindle fibers pull the separated chromatids (now called chromosomes) to opposite poles (ends) of the cell. This happens.

Answer:

• The chromosomes have split in half
• The chromosomes are moving to either end of the cell
