- Q1An eyepiece graticule has a scale with 100 divisions. A stage micrometer has a scale with 50 divisions, each of which is 0.040mm apart. Using a ×40 objective lens, the whole length of this stage micrometer scale lines up with 15 divisions of the eyepiece graticule. What is the actual length of the 100 division scale of the eyepiece graticule?75µm750µm13 mm1.3 mm60s
- Q2A prokaryotic cell which is 1µm in diameter, is magnified 50000 times in an electron micrograph. What is the diameter of the cell in the electron micrograph?5 × 102 mm5 × 100 mm5 × 101 mm5 × 10–1 mm60s

- Q4Which definition of the magnification of a drawing of a leaf is correct?the actual size of the leaf multiplied by the magnification of the microscopethe measured difference in size between the leaf and a drawing of the leafthe increase in size of the leaf when observed using a microscopethe size of the drawing of the leaf divided by the actual size of the leaf60s
