Question

scientists often replicate experiments to verify the findings. winch of the following is an example of replication? a scientist conducts three trials of her own experiment on the behavior of light. a scientist conducts a different experiment on heat after his first one does not support his hypothesis. a scientist repeats another scientists experiment on how sound waves travel. a scientist heats two different metals to compare the temperatures at which they melt.

Explanation:

Replication in science means repeating an experiment, often done by another scientist, to verify results. Conducting one's own multiple - trials is repetition, not replication. Conducting a different experiment is not replication. Heating different metals is a comparison experiment, not replication. Repeating another scientist's experiment is replication.

Answer:

A scientist repeats another scientist's experiment on how sound waves travel.
