1. Is oxygen the primary raw material for new living material?

• A. TRUE
• B. FALSE
• C. Not Sure
• D. None of the above

Correct answer: B

Rationale: While oxygen is essential for many living organisms, it is not the primary raw material for new living material. The primary raw materials for new living material are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur, collectively known as CHNOPS elements. These elements are the building blocks of biological molecules and are essential for life. Therefore, the correct answer is False. Choices C and D are incorrect because the primary raw materials for new living material are well-established in biology.

2. The anatomical term that indicates a structure close to the surface is

• A. anterior
• B. proximal
• C. superficial
• D. superior

Correct answer: C

Rationale: The correct answer is 'superficial.' In anatomy, the term 'superficial' refers to a structure that is close to the surface of the body. Choice A, 'anterior,' refers to the front of the body, not specifically to depth. Choice B, 'proximal,' refers to a structure that is closer to the point of attachment or trunk of the body. Choice D, 'superior,' indicates a structure that is above or higher in position.

3. The term 'physiology' is related to

• A. the Latin meaning of 'physical shape.'
• B. the structure of internal organs.
• C. the Greek for 'cutting up.'
• D. the Greek for 'relationship to nature.'

Correct answer: D

Rationale: The term 'physiology' originates from the Greek words 'physis' (meaning nature) and 'logos' (meaning study or relationship). Therefore, the correct answer is 'the Greek for 'relationship to nature.' Choice A is incorrect as it refers to the Latin meaning of 'physiology,' not the Greek origin. Choice B is incorrect as it is specific to the structure of internal organs, not the overall study of nature. Choice C is incorrect as it refers to a different term related to dissection or anatomy, not physiology.

4. In negative feedback mechanisms, changes away from the normal state

• A. stimulate changes in the same direction
• B. inhibit all body reactions
• C. stimulate changes in the opposite direction
• D. stimulate a reduction in all body requirements

Correct answer: C

Rationale: In negative feedback mechanisms, changes away from the normal state stimulate changes in the opposite direction. This is a fundamental concept in biological systems where the response to a stimulus opposes the initial change, helping to maintain homeostasis. Choice A is incorrect because negative feedback does not stimulate changes in the same direction. Choice B is incorrect because negative feedback does not inhibit all body reactions, but rather specific responses. Choice D is incorrect because negative feedback does not stimulate a reduction in all body requirements, but rather adjusts specific functions to restore balance.

5. Which of the following are vital signs?

• A. Body temperature, blood pressure, and pulse rate
• B. Appearance of the skin, red blood cell count, oxygen level
• C. Body weight, age, gender
• D. Visual acuity and auditory sharpness

Correct answer: A

Rationale: The correct answer is A: Body temperature, blood pressure, and pulse rate. Vital signs are measurements that indicate the body's basic functions and are essential indicators of health. Body temperature, blood pressure, and pulse rate are classic vital signs routinely checked in medical settings to assess a person's overall health status. Choices B, C, and D are not considered vital signs. The appearance of the skin, red blood cell count, and oxygen level may provide valuable health information but are not classified as vital signs. Similarly, body weight, age, and gender are important factors in healthcare but are not vital signs. Visual acuity and auditory sharpness relate to sensory functions and are not typically categorized as vital signs.
