Question

biochemistry quiz 5 of 16 a group of students conducted an experiment to study the growth of bean plants. they used two pots labeled \a\ and \b\. each pot contained 20 small bean plants of similar height. all the plants were treated alike except for the solution they received. each day for five days, the plants in pot a were given 40 milliliters of distilled water, while the plants in pot b were given 40 milliliters of distilled water containing one gram of fertilizer. the table below shows the average height of the plants in each pot for each day of the experiment. plant growth experiment day average height (centimeters) pot a: water only pot b: water plus fertilizer 1 2.0 2.0 2 2.2 2.3 3 2.3 2.8 4 2.5 3.2 5 2.6 3.8 which of these is being tested in this experiment? the maximum height the plants will reach the number of days the plants will grow the effectiveness of the water used on the plants the effectiveness of the fertilizer used on the plants

Explanation:

The experiment has two groups of plants. One group gets only water, the other gets water with fertilizer. The main difference between the two is the presence of fertilizer. By observing the plant - growth differences over time, the students are testing the impact of the fertilizer on plant growth.

Answer:

the effectiveness of the fertilizer used on the plants
