Multiple Choice

Which statement about variation in human anatomy and physiology is true?

Variation in anatomy and physiology can occur due to genetic differences and environmental factors.

Physiological variations are only observed in response to disease.

Anatomical variations are always pathological and require medical intervention.

All humans have identical anatomical structures and physiological functions.

Verified step by step guidance

Understand that human anatomy and physiology can vary among individuals due to several factors.

Recognize that genetic differences contribute to variations in anatomical structures and physiological functions. For example, genetic predispositions can affect height, skin color, and metabolic rates.

Consider the impact of environmental factors on physiological variations. These can include diet, climate, altitude, and lifestyle, which can influence things like lung capacity and muscle development.

Acknowledge that not all anatomical variations are pathological. Many are benign and do not require medical intervention, such as variations in the number of ribs or the presence of certain muscles.

Realize that the statement 'All humans have identical anatomical structures and physiological functions' is incorrect, as individual differences are a normal part of human diversity.
