The correct answer is D, the nucleus.
Explicación
## Step 1The problem is asking us to identify the part of the cell that breaks down during meiosis to allow chromosomes to separate and then redevelops during the last phase of the cell cycle. ## Step 2We need to consider the functions of each of the given options: vacuole, mitochondrion, cell membrane, and nucleus.## Step 3The vacuole is primarily involved in the storage of water and other substances. It does not play a direct role in the separation of chromosomes during meiosis.## Step 4The mitochondrion is the site of cellular respiration, where energy is produced. It does not directly participate in the separation of chromosomes during meiosis.## Step 5The cell membrane is the outer lining of the cell that controls the movement of substances in and out of the cell. It does not directly participate in the separation of chromosomes during meiosis.## Step 6The nucleus is the control center of the cell, containing the cell's DNA. During meiosis, the nuclear envelope breaks down to allow the chromosomes to separate. After meiosis, the nuclear envelope redevelops during the last phase of the cell cycle.
