Unit 1 Nature of Life and Biochemistry Review Game #1

Front

What do enzymes do?

Back

Enzymes speed up chemical reactions by lowering the activation energy required for the reaction to occur.

Front

What is a good hypothesis to answer the question, "Does the amount of salt in water cause it to boil faster?"

Back

If a person adds more salt, then the water will boil faster.

Front

What is a good hypothesis to answer the question, "Does fertilizer affect the growth of the plant?"

Back

If the amount of fertilizer is increased, then the plant height will increase.

Front

What type of macromolecules are sucrase and lactase?

Back

Sucrase and lactase are proteins.

Front

What is the first step of the scientific method?

Back

The first step of the scientific method is to identify a question or problem.

Front

What is the role of a hypothesis in scientific research?

Back

A hypothesis is a testable prediction that can be investigated through experimentation.

Front

Define macromolecules.

Back

Macromolecules are large, complex molecules that are essential for life, including proteins, nucleic acids, carbohydrates, and lipids.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

What is the difference between independent and dependent variables?

Back

The independent variable is the factor that is changed or controlled in an experiment, while the dependent variable is the factor that is measured or observed.

Front

What is a control group in an experiment?

Back

A control group is a standard of comparison in an experiment that is not exposed to the treatment or variable being tested.
