1. Which of the following must the human body obtain from the environment in order to survive?

• A. Nitrogen
• B. Waste products
• C. Water
• D. Carbon dioxide

Correct answer: C

Rationale: The correct answer is C: Water. Water is essential for the human body to survive as it plays a crucial role in various physiological processes like digestion, circulation, and temperature regulation. Nitrogen is abundant in the atmosphere and is not directly obtained from the environment for survival. Waste products are materials that need to be eliminated from the body, not obtained for sustenance. Carbon dioxide is a byproduct of cellular respiration and is expelled from the body through breathing, not obtained as a nutrient.

2. 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.

3. The activities of an anatomist consist of ______, whereas those of a physiologist consist of _____.

• A. observing body parts; studying functions of body parts
• B. conducting experiments; making microscopic examinations
• C. studying molecules; observing forms of the body parts
• D. sketching; dissecting

Correct answer: A

Rationale: An anatomist focuses on observing the structure and morphology of body parts, such as organs, tissues, and cells, to understand their organization. On the other hand, a physiologist is more concerned with studying the functions and processes of these body parts, including how they work individually and together to maintain homeostasis. Therefore, the correct answer is 'observing body parts; studying functions of body parts.' Choices B, C, and D are incorrect as they do not accurately reflect the primary activities of anatomists and physiologists.

4. When the body is placed in the anatomical position, which of the following is not true?

• A. The head is facing to the front.
• B. The palms are facing forward.
• C. The body is erect.
• D. The upper limbs are at the sides.

Correct answer: B

Rationale: In the anatomical position, the palms are facing forward, not backward. Choice A is correct because the head is indeed facing to the front. Choice C is correct as the body is erect. Choice D is correct as the upper limbs are positioned at the sides. Therefore, the incorrect statement is that the palms are facing forward.

5. 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.
