Answer questions #1-3 based on the following scenario. scientists tested the effect of a fertilizer on the growth of plants. they had 2 sets of plants, group a which gets fertilizer, water and sun and group b which gets only water and sun (but in equal amounts to group a). 1) explain how this sceniro is a controlled experiment and identify the manipulated variable 2)if the scientist only performed 1 experiment but it supported the hypothesis why can it not be considered a theory 3) the graph below was created showing the growth of the plant. how would you know that the y-axis is measuring the growth of the plant?

1) The scenario is a controlled experiment because there were controls and a single experimental group in order to find correlations in data. The manipulated variable would be the fertilizer because it is the only factor different between Group A and Group B.

2) A one-time trial is not sufficient enough in terms of evidence to support a theory. Theories have numerous repetitions and replications to prove the correlation to be strong.

3) (The graph does not appear, but I can assume there are labels on the axes.) The labels on the graph's axes show that the y-axis is the plant growth over time.

it would be rhyolitic hope this

condensation. good luck!
