Chapter 1, Problem 1PL

To explain biological phenomena, scientists use a technique called

1. the scientific method.
2. the scientific law.
3. conclusions.
4. measurements.

Summary Introduction

Introduction:

The scientific method is a series of different steps that can be used to collect knowledge about different biological phenomena. This technique involves five different methods. It starts with making observations, asking questions, formulating a hypothesis, carrying out an experiment, analyzing data, and creating a conclusion. Scientific experiments are examples of the scientific method.

Answer to Problem 1PL

Correct answer:

The correct answer is option (a) the scientific method.

Explanation of Solution

Explanation/justification for the correct answer:

Option (a).The scientific method. The scientific method is used to collect evidence in an experiment related to the hypothesis that supports or contradicts the theory. It is a technique that involves a series of steps to experiment. So, the correct answer is option (a)

Explanation for incorrect answer:

Option (b).Scientific law. The scientific law explains observations in the form of a verbal statement or a mathematical equation. It is different from the hypothesis and based on observation only. So, this is an incorrect option.

Option (c).Conclusions. Conclusions are a summary of the experiment. For a cause-effect experiment, the conclusion predicts whether the result of the experiment supports the hypothesis or not. So, this is an incorrect answer.

Option (d).Measurements. Measurements are a collection of quantitative data that describe the property of an object. Measurements are part of the scientific method. So, this is an incorrect answer.
