Answer:
- E. Does photosynthesis performed by elodea remove CO2 from the water?
- F. Does cellular respiration occur at a higher rate than photosynthesis in the tube with only elodea?
Explanation:
The tubes were placed under a growth light and as the elodea is growing, it would need photosynthesis to provide food. The color changes will therefore allow the students to see the effect photosynthesis has on the CO2 in the water by checking to see if the BTB turns blue which would mean that CO2 was removed by photosynthesis.
The students will also be able to see which process occurs faster in the tube with only elodea because the dominant color would show if cellular respiration occurs faster than photosynthesis or if the case is the reverse. For instance, if respiration is occurring faster, there will be more CO2 which would turn the BTB towards yellow, if photosynthesis is faster the BTB will turn towards blue and if the rates are similar, the BTB will remain green.
It tells the audience if the results support or contradict the hypothesis
Explanation:
When a scientist describes the materials that she used and how she performed her experiments, it tells the audience if the results supports or contradicts the hypothesis.
- A hypothesis formulation helps to test a scientific claims.
- Experiments are usually hinged on well designed hypothesis.
- From the hypothesis, one can be sure the experiment is tuned and designed within the scope of the observation desired to be tested.
- This is why the materials used and procedures followed in an experiment can tell if the results supports or contradicts the hypothesis.
