Biology Chapter 1 & 2

What Is A Hypothesis?

• A final conclusion based on extensive research.

• Educated guess as to the outcome.

• A detailed report of the results from an experiment.

• A random guess with no basis in evidence.

What are the constants in an experiment?

• The variables that are changed during the process of the experiment.

• The factors that are kept the same throughout the entire experiment.

• All the parts of the experiment that are identical in both the control group and the testing group.

• The results of the experiment that are measured and recorded.

In an experiment, what is the 'control'?

• Part of the experiment that is the same as the experimental group with only one difference.

• The group that receives the experimental treatment.

• The factor that is changed to observe its effect.

• The variable that is measured and recorded during the experiment.

What is an Independent variable?

• The variable that is kept constant throughout the experiment.

• The variable that is measured or observed as the outcome.

• The one variation from the control.

• The variable that is affection by changes in the dependent variable.

What is a dependent variable?

• That variable that is manipulated or changed during the experiment.

• The variable that remains constant throughout the experiment.

• The variable that is not measured or observed in the experiment.

• The outcome - which depends on what the independent variable was.

What is the function of Carbohydrates?

• To store genetic information in cells.

• To regulate body tempature.

• To build and repair tissues in the body.

• To serve as a primary energy source.

What is the function of Lipids?

• Develops the nervous system and hormones.

• Helps build bone and muscle.

• Stores genetic information.

• Quick source of energy.

What is the function of Proteins?

• Stores genetic information in the cell.

• Catalyze chemical reactions and help build bone and muscle.

• Store and transfer amino acids and develop the nervous sytsem.

• Provides a source of energy.

What is the function of Nucleic Acids?

• Stores and transfers genetic informations to make proteins.

• To provide energy to the cell for cellular activities.

• To regulate the blood sugar levels.

• To support and strengthen bones and muscles.
