Answer: (E)

Verified step by step guidance

1. Step 1: Understand the concept of physiology. Physiology is the branch of biology that deals with the normal functions of living organisms and their parts. It focuses on how organisms, organ systems, organs, cells, and biomolecules carry out the chemical and physical functions that exist in a living system.
2. Step 2: Analyze each question to determine if it pertains to physiology. Questions about physiology typically involve processes or functions within living organisms.
3. Step 3: Evaluate the first four questions. These questions are related to anatomical features or characteristics of different species, such as the number of toes, presence of tails, claws on wings, and teeth in whales. These are more related to anatomy rather than physiology.
4. Step 4: Consider the last question: 'How is blood pressure affected by physical activity?' This question is about the physiological process of how physical activity influences blood pressure, which is a function within the circulatory system.
5. Step 5: Conclude that the question about blood pressure and physical activity is the one related to physiology, as it involves understanding the functional changes in the body in response to physical activity.
