Back

The dependent variable is the factor that is measured or observed in an experiment, often affected by changes in the independent variable.

Front

What are the two main body systems that interact to deliver hormones?

Front

What are the two main systems involved when your skin itches due to a bug bite?

Back

The integumentary system and the nervous system are involved when your skin itches.

Front

What is an independent variable in an experiment?

Back

The independent variable is the factor that is changed or manipulated by the experimenter to observe its effect on the dependent variable.

Front

Define the term 'constant' in the context of an experiment.

Back

A constant is a factor that remains unchanged throughout the experiment to ensure that the results are due to the independent variable.

Front

What is the role of the circulatory system in the body?

Back

The circulatory system is responsible for transporting blood, nutrients, gases, and hormones to and from cells throughout the body.

Front

What is the function of the integumentary system?

Back

The integumentary system protects the body, regulates temperature, and provides sensory information through the skin, hair, and nails.

Front

What is the main function of the endocrine system?

Back

The endocrine system produces and secretes hormones that regulate various bodily functions, including growth, metabolism, and mood.
