1. alex wants to find out if different amounts of water affect plant growth. she waters three bean plants with three different amounts of water. she measures each plant’s height daily. she places all three plants in the same window to get sunlight. she keeps the temperature in the room set at 72°f. which option is the responding variable in this experiment? (1 point) the temperature of the room the amount of water the height of the plants the amount of sunlight

Explanation:

In an experiment, the responding variable (dependent variable) is what is being measured or observed as a result of changes in the independent variable. Here, Alex is testing how different amounts of water (independent variable) affect plant growth. The height of the plants is what she measures to see the effect of water amount. The temperature and sunlight are controlled variables (kept constant), and the amount of water is the independent variable (the one she changes).

Answer:

C. the height of the plants
