Answer:
This question is incomplete; the question is asking to identify variables such as the DV, IV, Constants etc
Independent variable (IV): Type of flowers
Dependent variable (DV): Growth of flowers
Constants: the same amount of sunlight, same amount of water
Explanation:
The independent variable is the variable that an experimeter changes or manipulates deliberately in order to bring about an effect in another variable. In this experiment, the TYPE OF FLOWER on each soil is changed by Alex, hence, it is the independent variable.
Dependent variable is the variable that is being measured in the experiment. It is the variable that responds to the changes made to the independent variable. In this case, the dependent variable is the GROWTH OF THE FLOWERS measured.
Constansts or control variable is the variable that the experimenter keeps constant or unchanged throughout the experiment in order to maintain the outcome of the experiment. In this case, the constants are the same amount of light, same amount of water
