Scientific Method
This variable is changed by the experimenter to test its effect.
What is the independent variable?

What is superior?
This plane divides the body into top and bottom parts.
What is the transverse plane?
The nasal cavity is part of this larger cavity grouping.
What is the cranial cavity?
The variable that is monitored and controlled in homeostasis is called this.
What is the set point?
A well-written hypothesis often follows this format, involving

What is the frontal (coronal) plane?
The lungs are found in this cavity.
What is the thoracic cavity?
This feedback loop controls oxygen levels by adjusting breathing rate.
What is negative feedback?
To ensure your experiment is fair, you must keep these variables the same.
