Question

scientist conducted this experiment with the tomato plants. in order to tell which plant grew the best under the light, they counted the number of tomatoes produced by each plant. this is called the: dependent variable conclusion independent variable constant

Explanation:

To determine the correct answer, we analyze each option:

• Dependent Variable: In an experiment, the dependent variable is what is being measured or observed and depends on the independent variable. Here, the number of tomatoes (growth measure) depends on the light (independent variable), so this is the dependent variable. But wait, let's check other options.
• Conclusion: A conclusion is the final summary of results, not what's being counted here. Eliminate.
• Independent Variable: The independent variable is the factor manipulated (like light color here), not the measured outcome. Eliminate.
• Constant: A constant is a factor kept the same, not what's being counted. Eliminate. Wait, earlier analysis had a mix - the number of tomatoes is the dependent variable as it's the outcome being measured (depends on light). So the correct option is the one labeled "Dependent Variable".

Answer:

A. Dependent Variable
