Nick is conducting a controlled experiment to test whether music helps daisies grow faster. Below are the steps to Nick's experi
ment: 1. Plant daisies in two separate flowerpots.
2. Place flowerpot 1 in a green room with music.
3. Place flowerpot 2 in a similar green room without music.
4. Give the daisies the same amount of food and water each week.
5. Measure the growth of the daisies.
6. Draw conclusions based on the data collected.
Which group is the control group in Nick's experiment?
FLOWERPOT 2 that was placed in the room without music
Explanation:
This question portrays an experiment performed by Nick to test whether music helps daisies grow faster. Nick performed this experiment using two separate flowerpots; he placed the first flowerpot in a room with music and the other flowerpot in a room without music. This shows that the independent variable is the MUSIC.
However, in an experiment, the CONTROL GROUP is the group that does not receive the experimental treatment (music). Based on this, the FLOWERPOT 2 (containing daisy) PLACED IN THE ROOM WITHOUT MUSIC IS THE CONTROL GROUP.
Stabilizing Selection; this type of natural selection selects against the extremes of a trait and favors only the intermediate phenotype, making the population look more similar overtime.
