Calculate actual size from magnification
A micrograph in a HL enzyme kinetics workshop shows a cell image length of \(66\) mm at \(\times 600\) magnification. Calculate actual cell length in micrometres. Enter the answer and choose the interpretation that best matches the HL biological evidence.
Worked practice: biological evidence and answer
Use the labelled biological evidence first, then connect it to the final answer.
