A student is measuring the lengths of caterpillars for an experiment. She measures 100 caterpillars using a ruler that measures
to the nearest centimeter. Which statement describes a change that could help improve the results of her experiment? O A. Her measurements will be more precise if she measures an additional 100 caterpillars. O B. Her measurements will be more accurate if she measures an additional 100 caterpillars. O C. Her measurements will be more accurate if she uses a ruler that measures to the nearest millimeter. O D. Her measurements will be more precise if she uses a ruler that measures to the nearest millimeter Please help
<em>The student's measurement would be more accurate if she can measure an additional 100 caterpillars and be more precise if she uses a ruler that measures to the nearest millimeter.</em>
<u>Accuracy refers to the closeness of measurement or group of measurements to the true value while precision is the closeness of repeated measurements. </u>
The accuracy of a measurement is increased by increasing the number of sample measurements. The more the sample measurements, the lesser the deviation of the mean from the true value.
The precision of a measurement is increased by being able to measure small differences. Hence, a ruler that measures to the nearest millimeter would be more precise than a ruler that can only measure in centimeter.
The statement water is easily polluted..... is true. Water is pretty much the world's best solvent. So even toxic substances are easily dissolved in it and when that happens they pollute the water.

alteration in cell kinetics pattern resulting in depletions of all populations.
