A group of high school students are conducting a scientific investigation in their biology class to study the effect of different types of fertilizer on the growth of tomato plants. Which of the following statements about their investigation is correct?(1 point) Responses The type of tomato plant is the dependent variable and the independent variable is the type of fertilizer The type of tomato plant is the dependent variable and the independent variable is the type of fertilizer The growth of the tomato plants is the dependent variable and the type of fertilizer is the independent variable. The growth of the tomato plants is the dependent variable and the type of fertilizer is the independent variable. The type of fertilizer is the dependent variable and the independent variable is the type of tomato plant. The type of fertilizer is the dependent variable and the independent variable is the type of tomato plant. The type of fertilizer is the dependent variable and the independent variable is the growth of the tomato plants.

Answer 1

In the context of their investigation, the correct statement is:

The growth of the tomato plants is the dependent variable and the type of fertilizer is the independent variable.

In this scenario, the independent variable is what the researchers are changing or manipulating (the type of fertilizer), while the dependent variable is what they are measuring or observing (the growth of the tomato plants).
