Question

1. josie set up an experiment to test the effect of light on tomato plants. the results of her experiment are shown below. what is the best conclusion she could make from this experiment? daily water 60 ml a daily water 60 ml b daily water 60 ml c no conclusion can be drawn from this experiment because it was not a fair test. tomato plants grow heaviest in dim light. tomato plants grown in bright light will be shorter but have more mass than tomato plants grown in dim light. tomato plants grow tallest in bright light.

Explanation:

The experiment has only one variable - light intensity (bright vs dim), with water amount and other factors kept constant. By comparing the height and mass of tomato plants in different light conditions, we can analyze the effect of light on plant growth. From the data, plants in brighter light seem to have different height and mass characteristics.

Answer:

Tomato plants grown in bright light will be taller but have less mass than tomato plants grown in dim light. (This is based on the trend shown in the data where plant A in bright - light has a higher height and lower mass compared to plant C in dim - light, though more replicates would strengthen the conclusion)
