Question

trudy made this venn diagram comparing interphase and cytokinesis. which statement belongs in the region marked x? is the longest stage dna is copied the number of nuclei doubles the number of cells doubles

Explanation:

• Is the longest stage: Interphase is the longest stage of the cell cycle, not cytokinesis. So this is incorrect for region X (which is only for cytokinesis - specific).
• DNA is copied: DNA is copied during interphase (S - phase of interphase), not during cytokinesis. So this is incorrect for region X.
• The number of nuclei doubles: The number of nuclei doubles during mitosis (when the nucleus divides). Cytokinesis is about the division of the cytoplasm. So this is incorrect.
• The number of cells doubles: Cytokinesis is the process by which the cytoplasm of a parental cell is divided into two daughter cells. So when cytokinesis is complete, the number of cells doubles. This is a characteristic of cytokinesis only.

Answer:

The number of cells doubles
