3. LAB 1 PRACTICE QUESTIONS
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.

4. LAB 1 PRACTICE QUESTIONS
The Microscope View

5. LAB 1 PRACTICE QUESTIONS
What You Know
50%
400 m = 0.4 mm

6. LAB 1 PRACTICE QUESTIONS
The Final Step
50%
50 % X 400 m =
400 m = 0.4 mm

7. LAB 1 PRACTICE QUESTIONS
The Answer
50%
50 % X 400 m =
200 m or
0.2 mm
400 m = 0.4 mm

8. LAB 1 PRACTICE QUESTIONS

17. 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

18. LAB 1 METRIC LENGTH REVIEW
EXAMPLES:
1 kilometre (1km) = 1000 metres
1 metre (1m) = 1000 millimetres
1 millimetre (1mm) = 1000 micrometre
micrometre (1m) = 1000 nanometre (nm)

19. LAB 1 METRIC LENGTH REVIEW
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

20. LAB 1 METRIC QUESTIONS
2.6 mm is equal to
_______ cm
_______ m
_______ nm

21. LAB 1 METRIC QUESTIONS
2.6 mm is equal to cm m nm
