Question

1. what is the dependent or responding variable? 10 p a number of tomatoes b water c sunlight d classical music 4. what is the experiments control group? 10 po a plant a b plant b 5. what is the experiments constants? * 10 poi a water b music c headphones

Explanation:

Question 3

In an experiment, the dependent variable is what is being measured or observed, which depends on other factors. Here, the number of tomatoes is the outcome being measured (e.g., how many tomatoes grow based on other factors like water, sunlight, music). Water, sunlight, and classical music are independent variables or factors being tested.

The control group in an experiment is the group that does not receive the experimental treatment, used for comparison. If Plant A is the control, it likely doesn't get the variable being tested (e.g., music) while Plant B might be the experimental group.

Constants in an experiment are factors kept the same for all groups. Water is likely kept constant (same amount for all plants) to ensure only the experimental variable (like music) affects the outcome. Music is the variable, and headphones are not a constant related to plant growth.

Answer:

A. A number of tomatoes
