Chapter 9, Problem 9STP

Summary Introduction

Introduction : All scientists and biologists follow the same basic steps to do research and answer queries. These are called scientific methods.They conduct experiments, collect data, make hypothesis and gather evidences.

Answer to Problem 9STP

Correct answer :

The correct answer is option A. A conclusion would be established.

Explanation of Solution

Explanation/justification for the correct answer:

Option A. A conclusion would be established−Scientists gather information from various experiments. This informationis called data. They then analyze the data and decide if the data supports the hypothesis. The experiments are conducted over and over again to gather more data. If data from repeated experiments support a hypothesis, then a conclusion is drawn. Hence this is the correct option.

Explanation for incorrect answer

Option B. The data would become a law- If data from repeated experiments support a hypothesis, then a conclusion is drawn.The scientists also compare the results of their experiments with the results of other studies. The results are also published in science journals so that the scientists can compare different results. After many repeated experiments when the results are similar, then the hypothesis becomes a theory/ law. Hence this is not a correct option.

Option C. The hypothesis would be rejected- If data from repeated experiments support a hypothesis, then a conclusion is drawn.If the data does not support the hypothesis then it sis revised and tested for alternate hypothesis. Hence this is an incorrect option.

Option D.The hypothesis would be revised - If data from repeated experiments support a hypothesis, then a conclusion is drawn.If the data does not support the hypothesis then it sis revised and tested for alternate hypothesis. Hence this is an incorrect option.
