Answer:
The correct answer to the question: Which of the following hypotheses is both falsifiable and testable:____, would be, B: If all plants are watered at least once a day then they will all grow at least 1 cm a day.
Step-by-step explanation:
In order to carry out research, hypothesis must be generated that will ask the questions necessary to find out information on different topics. However, not all questions, or statements will serve as a source for research, or lead to research. For this to happen, a researched must know that there are conditions to how to formulate a hypothesis; the first condition is that the hypothesis must be verifiable, or testable, which means, it can be proven. The second is, that the hypothesis must be falsifiable, or refutable, by research, and the third, the hypothesis must lead to results that can lead to further testing and reproduction. In this case, saying that all plants, when watered once a day at least, will grow a minimum of 1 cm a day cannot be used because it is based on a wrong assumption, given that all plants grow at different rates, and not all can be watered in the same way. This, in itself, from the outset, invalidates the hypothesis.
