Exploring the Scientific Method in Biology

What is the primary goal of the biology EOC review?

• To conduct experiments in the laboratory

• To learn about the history of biology

• To memorize the characteristics of living things

• To prepare for the biology EOC at the end of April

Which is NOT a characteristic of all living things?

• Ability to reproduce

• Containment of DNA

• Response to stimuli

• Use of energy through photosynthesis only

What does a hypothesis represent in an experiment?

• A record of the observations made during the experiment

• A detailed description of the experimental procedure

• A summary of the experiment's results

• A testable prediction about the experiment's outcome

What is the role of a control in an experiment?

• To ensure the safety of the experiment

• To measure the outcome of the experiment

• To be the variable that is manipulated by the scientist

• To remain unchanged to serve as a standard for comparison

What does the independent variable represent in an experiment?

• The standard for comparison

• The outcome that is measured

• The variable that the scientist changes

• The variable that is kept constant

Which type of data is represented by numbers?

• Qualitative data

• Quantitative data

• Theoretical data

• Hypothetical data

Which graph is typically used to represent continuous data?

• Pie chart

• Bar graph

• Histogram

• Line graph

What is the purpose of using graphs in experiments?

• To predict the outcome of future experiments

• To replace numerical data with images

• To visually represent data for easier interpretation

• To make the report look more professional

What is the main difference between a scientific theory and a law?

• A theory can never become a law

• A law states what happens; a theory explains why

• A theory is less accurate than a law

• A law is a prediction; a theory is an observation

Which is an example of a scientific law?

• The hypothesis of natural selection

• The cell theory

• The law of gravity

• The theory of evolution
