  1. Question 1

    Q1. A cytologist observes that a secretory cell has 30,000 nuclear pores, while an undifferentiated cell has few. What determines this numerical variation?

    • A) Surface area of the nucleus
    • B) Volume of the nucleoplasm
    • C) Thickness of the nuclear lamina
    • D) Physiological activity of the cell

    Answer: Physiological activity of the cell
