Question

what happens during interphase?
the nucleus grows to its full size.
the cell grows to its full size.
the nucleus divides into two nuclei.
the cell divides into two cells.

Explanation:

Interphase is the phase of the cell cycle where the cell prepares for division. During interphase, the cell grows to its full size, replicates its DNA, and prepares organelles. The nucleus does not divide (that's mitosis/meiosis), and the cell doesn't divide into two cells (cytokinesis or mitotic/meiotic division). The nucleus growing to full size isn't a main event of interphase; the cell's growth (including organelle production, DNA replication) involves the cell growing to its full size before division. So the correct event during interphase is the cell growing to its full size.

Answer:

The cell grows to its full size. (Corresponding to the third option: "The cell grows to its full size.")
