There's a great picture that I attached below that is a great representation
The data did not support the hypothesis because the amount of dissolved oxygen decreased as water temperature increased.
Answer:
D. An observation is based on evidence, an inference is not.
Explanation:
When you infer something, you're basically guessing at it, while an observation is something that you can see and prove.
The control group is the one not given calculators because they are the “as seen in nature” group. The experimental group would be the ones with calculators.
Lima beans in soil of pH 6.8 grew better than that in soil of pH 7.9 showing that a slightly acidic soil is best for growth of Lima beans.
<h3>What is the purpose of the experiment?</h3>
The purpose of the experiment is to determine the effect of soil pH of growth of Lima beans.
Lima beans is known to have maximum growth in soil pH of 6.0 to 6.8.
The Lima beans are planted in soil of pH 7.9 (watered with creek water) and soil of pH 6.8 (watered with a solution of Miracle grow).
It was observed after ten days, that the Lima beans in soil of pH 6.8 grew better than that in soil of pH 7.9 which did not grow.
In conclusion, Lima beans grows best in soil of pH that is slightly acidic.
