Propose a suitable title, state a hypothesis, and identify the independent and dependent variables for an experiment investigating catalase distribution in a pawpaw plant.

A suitable title should reflect the aim of the experiment, which is to compare catalase activity in different parts of the pawpaw.

• Title: Investigation into the Distribution of Catalase Enzyme in Different Parts of the Pawpaw Plant

A hypothesis is a testable statement predicting the outcome.

• Hypothesis: Different parts of the pawpaw plant (seeds, fruit, and stalk) will contain varying concentrations of the catalase enzyme, leading to different rates of hydrogen peroxide breakdown.

The independent variable is the factor that is intentionally changed or varied by the experimenter.

• Independent variable: The specific part of the pawpaw plant (seeds, fruit, or stalk).

The dependent variable is the factor that is measured or observed in response to changes in the independent variable.

• Dependent variable: The amount or activity of catalase enzyme (e.g., measured by the rate of oxygen production/fizzing when hydrogen peroxide is added).
