LAB 1 PRACTICE QUESTIONS

1 The microscope you are using has a field diameter of 400 m when using the 40x objective. A cell which fills 50% of the field of view at 40x would be ________ in diameter.


The Microscope View


What You Know

400 m = 0.4 mm

50%


The Final Step

400 m = 0.4 mm

50%50 % X 400 m =


The Answer

400 m = 0.4 mm

50%50 % X 400 m =

200 m or0.2 mm


2 The microscope you are using has a field diameter of 0.5 mm when using the 40x objective. A cell which fills a quarter of the field of view at 40x would be ________ in diameter.

LAB 1 METRIC LENGTH REVIEW

ALL LENGTHS OR DISTANCES IN METRIC ARE BASED ON THE UNIT OF THE METRE

THE MOST COMMON PREFIXES CHANGE BY UNITS OF 1000


EXAMPLES: 1 kilometre (1km) = 1000 metres 1 metre (1m) = 1000 millimetres 1 millimetre (1mm) = 1000 micrometre

micrometre (1m) = 1000 nanometre (nm)


The exception to the 1000 rule for distance conversions is cm’s

1 metre is equal to 100 cm and 1 cm is equal to 10 mm

1 cm = 10 mm

LAB 1 METRIC QUESTIONS

2.6 mm is equal to ? _______ cm? _______ m? _______ nm

LAB 1 METRIC QUESTIONS

2.6 mm is equal to ? 0.26 cm? 2600 m? 2600000 nm
