1. The recent discovery of taste receptors that detect sweetness in the small intestine illustrates that
- A. chemical responses occur in various parts of the body.
- B. new discoveries about anatomy and physiology are still being made.
- C. everything about anatomy and physiology has been discovered.
- D. the molecular and cellular level is crucial in anatomy and physiology.
Correct answer: B
Rationale: The recent discovery of taste receptors in the small intestine illustrates that new discoveries about anatomy and physiology are still being made. This finding demonstrates that our understanding of the human body is continuously evolving. Choice A is incorrect because the discovery does not imply that chemical responses occur in only one part of the body but rather showcases a specific new discovery. Choice C is incorrect as it is highly improbable that everything about anatomy and physiology has been discovered given the complexity of the human body. Choice D is incorrect as while the molecular and cellular level is important in anatomy and physiology, the primary focus of this discovery is on the new findings about the taste receptors in the small intestine.
2. What is the main function of the digestive system?
- A. Formation of cells
- B. Movement of body parts
- C. Absorption of nutrients
- D. Providing oxygen for the extraction of energy from nutrients
Correct answer: C
Rationale: The correct answer is C: Absorption of nutrients. The main function of the digestive system is to break down food into nutrients that can be absorbed by the body to provide energy and support bodily functions. Choice A, 'Formation of cells,' is incorrect as cell formation is not the primary function of the digestive system; it is more related to processes like cell division and growth. Choice B, 'Movement of body parts,' is incorrect as this is more related to the muscular system, which controls body movements. Choice D, 'Providing oxygen for the extraction of energy from nutrients,' is incorrect because providing oxygen is primarily the function of the respiratory system, which is responsible for breathing and oxygen exchange in the body, not the digestive system.
3. Specialized cell types organized in a way that provides a specific function form
- A. tissues, which build organs.
- B. organs, which build tissues.
- C. organ systems, which build tissues.
- D. atoms, which comprise tissues.
Correct answer: A
Rationale: The correct answer is 'tissues, which build organs.' Specialized cell types organize to form tissues, which in turn build organs. Tissues are groups of cells that work together to perform a specific function. Option B is incorrect because organs are composed of tissues, not the other way around. Option C is incorrect as organ systems consist of multiple organs working together, not building tissues. Option D is incorrect as atoms are the basic building blocks of matter and are not directly involved in forming tissues.
4. Temperature is a form of energy, whereas heat is a measurement of the intensity of the temperature.
- A. TRUE
- B. FALSE
- C. Not Sure
- D. None of the above
Correct answer: A
Rationale: The statement is true. Temperature is a measure of the average kinetic energy of the particles in a substance, while heat is the transfer of energy from a hotter object to a colder one. Heat is not a measurement of the intensity of temperature, but rather the energy transfer due to a temperature difference. Therefore, the correct answer is True. Choice B (False) is incorrect as the statement is true based on the definitions of temperature and heat.
5. The origin of the term 'anatomy' is related to
- A. the Greek word for 'function.'
- B. the name of the first anatomist.
- C. the Greek word for 'cutting up.'
- D. the function of internal organs.
Correct answer: C
Rationale: The correct answer is C: the Greek word for 'cutting up.' The term 'anatomy' originates from the Greek words 'ana' (up) and 'temnein' (to cut), which means 'cutting up' or 'dissection.' This term refers to the process of dissecting bodies to study their structure. Choices A, B, and D are incorrect because 'anatomy' is not related to the Greek word for 'function,' the name of the first anatomist, or the function of internal organs, but rather to the act of cutting up for study and examination.
