Question 1

An electron micrograph shows drawings of a eukaryotic nucleus and a lysosome.

  • For the nucleus:

    • The scale bar indicates that a length of 3.0 cm on the drawing represents an actual diameter of 2.4 μm2.4\ \mu\text{m}2.4 μm.
    • The measured diameter of the nucleus on the drawing is 7.5 cm.

  • For the lysosome:

    • The scale bar indicates that a length of 2.5 cm on the drawing represents an actual diameter of 250 nm250\text{ nm}250 nm.
    • The measured diameter of the lysosome on the drawing is 4.0 cm.

Calculate how many times larger the actual diameter of the nucleus is than the actual diameter of the lysosome. Show your working.
