Question 9 why do scientists prefer to use the metric system? a. it allows for more accurate measurements b. it reduces systematic error. c. it reduces random error. d. it is based on invariant natural constants. e. calculations can be done using calculators

Option A.

Explanation:

It allows for more accurate measurements, is the right answer.

The scientists prefer to use the metric system due to the fact that through this they can accurately compare their findings. This system is used throughout the world to measure weight, volume and distance. In this system, there are three basic units of which all the others are measured; meters for length, grams for weight and seconds for time. In short, this system gives the same standards of measurement to the scientists at the time when they conduct experiments.
