Answer:

B and C

Explanation:

<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.

<u>The correct option is B and C.</u>

KatRina [158]
When tiny ice crystals in clouds stick together to form snowflakes, the result is snow. If enough crystals form a clump, they'll become heavy enough to fall to the ground. When temperatures are cold and moisture in the form of tiny ice crystals exists in the atmosphere, snow forms.
