Jackie read that Aloe vera promote healing on burned tissue. She decided to investigate the effect of various amounts of Aloe ve
Anon25 [30]

Answer:

Hypothesis: IF Aloe vera is applied, THEN the number of regenerated planaria will increase

Independent variable: The different amounts of Aloe vera applied

Dependent variable: Number of regenerated planaria

Control group: The parts of planaria that received 0% of Aloe vera

Conclusion: The Hypothesis should be rejected

Explanation:

Hypothesis in an experiment is a testable explanation to an observed problem. It aims at proferring a possible solution/answer to a question. In this experiment, the hypothesis will be: IF Aloe vera is applied, THEN the number of regenerated planaria will increase

The independent variable refers to the variable being manipulated or changed in the experiment while the dependent variable is the variable that responds to the changes made to the independent variable. The dependent variable is the measured variable. In this experiment, the independent variable is THE DIFFERENT AMOUNTS OF ALOE VERA APPLIED while the dependent variable is THE NUMBER OF REGENERATED PLANARIA.

The control group of an experiment is the group that differs from the experimental group by not receiving the experimental treatment (independent variable). In this experiment, the control is the PART OF PLANARIA THAT RECEIVES 0% OF ALOE VERA.

Based on the outcome of the experiment, it can be seen that there was an initial increase in number of regenerated planaria but the number later declined, hence, the hypothesis given will be REJECTED as it doesn't explain the declination.
