In a science experiment, 10 tomato plants were given fertilizer in their water each week and 10 tomato plants were given plain water each week. All other factors were the same for all plants. At the end of each week, the height of each plant was measured. What was the independent and dependent in the experiment? 1. the height of the plant

2. the amount of water given

3. the type of plant

4. whether or not there was fertilizer in the water

Independent: whether or not there was fertilizer in water

Dependent: height of plants

Explanation:

In an experiment, there is an independent and a dependent variable. The independent variable is what is changed in the experiment. The dependent variable is what is measured.

In this experiment, 10 tomato plants are given fertilizer in the water, while 10 other tomato plants are given regular water. Everything else is kept constant, and the heights are measured at the end of the week.

The independent variable is what is being changed. In this experiment, the only thing being manipulated is the fertilizer. One group of the plants is given fertilizer, while the other is not. Therefore, the independent variable is whether or not there was fertilizer in the water.

The dependent variable is what is being measured. In this experiment, the thing that is being measured is the height of the plants. Therefore, the dependent variable is the height of the plants.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
