1. Independent Variable – This is the element changed or controlled in an experiment. Here, it is the labs, since they are given to one class but not the other.
2. Dependent Variable – This represents what is measured in the experiment and depends on the independent variable. In this case, it is the average test scores.
3. Hypothesis – A testable prediction. Here, it suggests that the class participating in labs will perform better than the one without labs.
4. Control Group – The group that does not receive the experiment variable; in this example, the class without labs.
5. Experimental Group – The group exposed to the variable being tested, here the class that completes labs.
6. Constants – The same quantity and type of notes and homework provided to both classes.
7. Possible threats to accuracy – Potential issues include improper application of independent or dependent variables, or misuse of statistical analysis, among others.
Answer:
Ethylene. (Ans. D)
Explanation:
Ethylene controls the aging and ripening processes in plants. While many fruits and vegetables generate small amounts of ethylene, climacteric fruits like bananas produce larger quantities. This ethylene release accelerates respiration, triggers more ethylene production, and causes changes in color and flavor.
Therefore, when transporting green bananas over long distances to stores, the ethylene gas should be removed from their surrounding environment.
