What is the primary difference between anatomy and physiology?
Anatomy focuses on function, while physiology focuses on structure.
Anatomy is the study of structure, while physiology is the study of function.
Anatomy and physiology both study the same aspects of the body.
Physiology is the study of diseases, while anatomy is the study of health.
Which of the following best describes the scientific method?

Why is the concept of variation important in anatomy and physiology?
It allows for the study of identical organisms.
It explains why all organisms are the same.
It helps understand the differences and adaptations in organisms.
