What is the correct order for the scientific method?

Back

The correct order is: problem, hypothesis, experiment, analyze data, draw conclusions.

Front

The pH scale is based off of the concentration of _________ ions.

Back

The pH scale is based off of the concentration of Hydronium (H+) ions.

Front

Identify the DEPENDENT variable in the experiment about water spurt from a milk carton.

Back

The dependent variable is the distance water traveled out of the carton.

Front

What factors affect an enzyme's reaction rate?

Back

Factors that affect an enzyme's reaction rate include temperature, pH, and substrate concentration.

Front

Which substance is more acidic than lemon juice according to the pH range?

Back

Hydrochloric acid is more acidic than lemon juice.

Front

Define hypothesis in the context of the scientific method.

Back

A hypothesis is a testable prediction about the relationship between variables.

Front

What is the role of a control group in an experiment?

Back

The control group serves as a baseline to compare the effects of the independent variable.

Front

Explain the significance of the independent variable in an experiment.

Back

The independent variable is the factor that is manipulated to observe its effect on the dependent variable.

Front

What is the function of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up biochemical reactions without being consumed.

Front

Define pH and its importance in biology.

Back

pH is a measure of acidity or alkalinity of a solution, important for enzyme activity and cellular functions.
