A group of biology students conducted a lab to study the effect of water on plant growth. They used the following procedure: 1 – Germinate nine bean seeds. 2 – Put three bean plants each into three identical pots containing the same weight and type of soil. Label the pots A, B, and C. 3 – Place pots in an area where they can receive the same amount of sunlight. 4 – Each day pour 30 mL of water into pot A, 20 mL of water into pot B, and 10 mL of water into pot C. 5 – Measure and record the height of the plants every other day for 15 days. Recorded data: Which was a limiting factor for this experiment? A amount of soil B size of the pots C amount of water D amount of sunlight
