Question 1 of 5
In the early days, healers transitioned from superstition and magic to using natural chemicals in the field of medicine.
Correct Answer: A
Rationale: The statement is true. The field of medicine evolved as early healers moved away from superstition and magic, instead focusing on natural chemicals to treat illnesses. This transition marked a shift towards a more scientific and evidence-based approach to healthcare. Choice B is incorrect because the statement accurately reflects the historical development of medicine. Choice C is incorrect as the historical transition from superstition to natural chemicals is a well-documented aspect of the evolution of medicine. Choice D is incorrect as the statement provided is true.
Question 2 of 5
Macromolecules are built of
Correct Answer: A
Rationale: The correct answer is A: Monomers. Macromolecules are built from smaller subunits called monomers. Monomers join together through chemical reactions to form larger molecules known as macromolecules. Option B is incorrect because it does not provide the accurate information regarding macromolecules. Option C is incorrect as it indicates uncertainty, which is not the case here. Option D is incorrect as there is a specific answer related to the composition of macromolecules.
Question 3 of 5
Most of the terminology to name and describe body parts and their functions comes from
Correct Answer: A
Rationale: The correct answer is Latin and Greek. Medical terminology is largely derived from Latin and Greek roots. These languages have been foundational in the development of medical terminology due to the precision and descriptive nature of their vocabulary. Choice B, English and Italian, is incorrect because while some medical terms may have originated from these languages, the majority come from Latin and Greek. Choices C and D, pictures drawn on the cave walls of our ancestors and the language of hunter-gatherers, are both incorrect as they do not align with the historical origins of medical terminology.
Question 4 of 5
An investigator who conducts an experiment to determine how temperature changes affect the rate at which the heart beats is most likely a(n)
Correct Answer: B
Rationale: The correct answer is 'physiologist.' A physiologist studies how the body functions under normal and abnormal conditions, including how temperature changes can affect physiological processes like heart rate. An anatomist focuses on the structure of organisms rather than their functions, making choice A incorrect. Choices C and D are also incorrect as they are more related to the study of chemicals and biochemistry, which are not directly relevant to investigating the effects of temperature on heart rate.
Question 5 of 5
Why are anatomy and physiology difficult to separate?
Correct Answer: A
Rationale: Anatomy and physiology are difficult to separate because physiological functions depend on anatomical structures. The correct answer highlights the interdependence between the two disciplines; physiological functions are carried out by anatomical structures. Choice B is incorrect as it only states a characteristic of physiological functions without addressing the relationship with anatomy. Choice C is incorrect as it talks about body parts providing structural support, which is not directly related to the interdependence of anatomy and physiology. Choice D is incorrect because the rate of change in understanding does not necessarily dictate the difficulty of separating the two disciplines.
