After conducting the experiment, the students wrote the conclusion below. Which sentence provides evidence to support the claim that type of water does have an effect on plant growth?
In this experiment, they tested if the type of water affects the height of a plant. The hypothesis stated, "If rainwater, tap water or bottled spring water were used to grow a plant then bottled spring water would produce the tallest plant." This hypothesis was somewhat supported. When a plant was place in a pot with 200 grams of soil and watered daily the plant grew, on average 0.11 cm more than the shortest plant tested. Research has shown that the air and water pollution does have a direct effect on the growth a plant. Plants also need an adequate supply of sunlight . Two of the three plants were grown indoors, therefore, amount of natural sunlight could have an effect on plant growth and would need to be tested further. The students decided they would investigate the affects of natural sunlight on plant growth for an extended investigation.

Based on the following excerpt, which of the following statements correctly provides scientific reasoning to support the claim? (choose 2)
Polluted water due to acid rain actually washes the essential nutrients plants need out of the soil. Water pollution makes the soil acidic and negatively affects the solubility or dissolvability of nutrient ions, such as iron, magnesium, potassium and calcium ions. As a result, water removes these nutrients more quickly from the soil and sends them into streams and lakes. Calcium and magnesium in particular are critical for proper plant growth. Iron helps plants to create the pigment chlorophyll, which is necessary for food formation, while potassium helps plants to use water. Without these nutrients, plants become more susceptible to drought, fungal infections and insects. Water pollution also leaves large amounts of aluminum in the soil, which can be harmful to plants. Acid rain contains sulfuric and nitric acid, which can damage tree leaves and bark and hurt the fine root hairs of many plants. Plants need these fine root hairs to absorb water.
