Answer:
her degree of accuracy in measurement is 0.05 cm (Option D)
Step-by-step explanation:
The degree of accuracy in the measurement of the botanist depends on the instrument used.
For a length of 3.56 centimeters, it shows that the length of the tomato seedling was measured using meter rule or tape.
Meter rule is graduated in 1 mm or 0.1 cm. The estimated uncertainty in measurement using meter rule is half of its graduation i.e ( ¹/₂ of 0.1 cm = 0.05 cm).
If the botanist measured the length of tomato seedling as 3.56 centimeters, then her degree of accuracy in measurement is 3.56 cm ± 0.05 cm.
Therefore, her degree of accuracy in measurement is 0.05 cm (Option D)
