Question

15 multiple choice 2 points a student will measure and record the growth of two flowering plants every other day for 10 days. according to the diagram, which question is being tested? do flowering plants grow better when watered with salt water? how much fertilizer do flowering plants need? does fertilizer added to the soil lead to taller flowering plants? how tall do flowering plants grow?

Explanation:

The experiment has two plants. One has fertilizer added, the other does not. The variable is the presence of fertilizer. The measured outcome would be related to plant growth (taller, as height is a common measure of growth).

• The first option about salt - water is not relevant as there is no salt - water in the experiment.
• The second option about "how much" fertilizer is not addressed as there is no variation in fertilizer amount (only presence/absence).
• The fourth option is too general as it doesn't mention the role of fertilizer.

Answer:

Does fertilizer added to the soil lead to taller flowering plants?
