Student conducts an experiment to see how music affects plant growth. the student obtains four identical plants. each one is potted in the same type of soil and receives the same amount of sunlight and water each day. plant a listens to classical music for three hours each day. plant b listens to rock music for three hours each day. plant c listens to country music for three hours each day. plant d does not listen to any music at all. 1. based on the experiment in the scenario, which visual aid would be most in showing the change in the plants' heights over time? a. a line graph b. a bar graph c. a pie chart d. a timeline

a line graph or a bar chart

Explanation:

Option A, A line graph

Explanation:

Continuous changing trends or variable with continuous changing values are best represented by a line graph.

Since the height of plants will be a continuous changing process, it will be plotted in the form of line.

On the other hand a bar graph shows a comparison between certain set of quantities. A pie chart represent share of sub group variable forming the main group variable.

A time line is representation of time on graph.

Hence, option A is the most appropriate graph to show the change in the plants' heights over time

the answer for this question would be d. glaciers

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
