Explanation:
You ned to take a picture showing the full question, or none of the answers we give you will be accurate without knowing what it’s asking.
The question is incomplete, however the correct question is as follows:
A 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.
2. In the experiment described in the scenario, which group represents the control group?
A. Plant A
B. Plant B
C. Plant D
D. Plant C
Answer:
The correct answer is - option C.
Explanation:
In a experimental setup an independent variable is the one which can be changed or controlled in an experiment. The progressions happening in the independent variable liable to influence the results of the dependent variable. The dependent variable can't be controlled however the progressions happening in this variable happens because of the adjustments in the independent variable. The control group is the one which is utilized as a standard in a test arrangement to analyze the changes happening in the tested sample as for the utilization of the controlled variables.
As per the given circumstance, the music is the independent variable over which the development of the plant is reliant upon. Thus, the development of the plant is dependent variable. The control group is the Plant D which doesn't listen in to any music whatsoever. This is kept in the analysis to decide whether development of plant is reliant upon music or normal conditions, for example, soil, daylight and water are adequate.
