Explanation:

Question 14:

PMAT is an acronym for the stages of mitosis. Each letter represents a distinct phase in the process of cell division (mitosis).

• P: Prophase - Chromosomes condense, the nuclear envelope breaks down, and the mitotic spindle forms.
• M: Metaphase - Chromosomes align at the cell's equatorial plate (metaphase plate).
• A: Anaphase - Sister chromatids separate and are pulled to opposite poles of the cell by the spindle fibers.
• T: Telophase - The nuclear envelope reforms around the separated chromosomes, and the cell prepares to divide into two daughter cells (cytokinesis often follows).

Answer:

• P: Prophase
• M: Metaphase
• A: Anaphase
• T: Telophase
