What is the definition of an Experimental Group?

• The group in an experiment that receives the treatment or condition being tested.

What is the definition of metabolism?

• The process by which organisms reproduce and grow.

• The combination of chemical reactions through which an organism builds up or breaks down materials.

• The method by which organisms respond to environmental changes.

• The way in which organisms obtain energy from sunlight.

What is a Dependent Variable?

• The factor that is measured and changes as a result of the independent variable.

• A variable that remains constant throughout the experiment.

• The variable that is manipulated by the researcher.

• A variable that is not affected by any other variables.

What is cellular respiration?

• The process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

• The process of photosynthesis in plants to create glucose.

• A process by which organisms become more similar to each other over time.

• The ability of an organism to change its behavior in response to environmental changes.

What is the scientific method?

• A systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

• A random approach to solving problems without any structured process.

• A method used exclusively in laboratory settings for conducting experiments.

• A way to gather opinions and beliefs without empirical evidence.

What is the purpose of a hypothesis in scientific research?

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

• A hypothesis is a definitive conclusion drawn from data.

• A hypothesis is an untestable statement about the future.

• A hypothesis is a summary of existing research findings.

What is a food chain?

• A series of organisms each dependent on the next as a source of food.

• A type of food that chains ingredients together.

• A network of food webs in an ecosystem.

• A method of preserving food for long periods.

What is an Independent Variable?

• The factor that is changed or manipulated in an experiment.

• The outcome that is measured in an experiment.

• A variable that remains constant throughout the experiment.

• A variable that is not affected by other variables.
