Question

an experiment was carried out to answer the question \does the ph of water affect the growth of radish plants?\. two groups of ten radishes were set up. one group was watered with water having a ph of 3.0, and the other group was watered with water having a ph of 7.0. both groups of plants received the same intensity of light, the same amount of water, and they were grown in the same type of soil. the heights of the radish plants were measured every 2 days for a period of 2 weeks. which sentence is a possible hypothesis that could be tested in this experiment? does the ph of water affect the growth of radish plants? will the amount of water alter the heights of radish plants? the ph of the water will affect the heights of the radish plants. the temperature of the water will affect the heights of the radish plants.

Explanation:

Step1: Identify the experiment's focus

The experiment is testing the effect of water pH on radish - plant growth.

Step2: Analyze each statement

The statement "Does the pH of water affect the growth of radish plants?" is the hypothesis being tested in the experiment as it directly relates to the variables being manipulated (pH of water) and measured (growth of radish plants). The other statements about temperature and amount of water are not part of this particular experiment's focus.

Answer:

Does the pH of water affect the growth of radish plants?
