The answer to this is the Immune System.
The Immune system is made up of a network of cells and tissues and organs that work together to protect the body. The white blood cells (also known as Leukocytes) is part of the immune system, they help destroy disease causing organisms or substances.
That is why when you fall ill and like a few days later you are all better, that is because of the immune system.
Sometimes when somebody has a weak immune system they fall ill more easily and could die because the bacteria that makes you sick isn't being destroyed by the immune system. Sometimes the person has to go to the hospital for treatment and some medications that can help support their immune system.
Hope this helped :)
Have a great day

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.
