1. Pulse, temperature, and respiration are known as ___________.

• A. vital signs
• B. vital statistics
• C. vital force
• D. vital capacity

Correct answer: A

Rationale: Pulse, temperature, and respiration are collectively known as vital signs. These measurements provide important information about a person's overall health status and are essential in assessing a person's well-being in various medical settings. Choice B, 'vital statistics,' is incorrect as vital statistics usually refer to data related to births, deaths, marriages, and health. Choice C, 'vital force,' is incorrect as it refers to a concept in some alternative medicine practices and is not a standard medical term for these measurements. Choice D, 'vital capacity,' is incorrect as it specifically refers to the maximum amount of air a person can expel from the lungs after a maximum inhalation, not a combination of pulse, temperature, and respiration.

2. ___________ is a symbiotic relationship in which one organism benefits and the other is not affected.

• A. Mutualism
• B. Parasitism
• C. Commensalism
• D. Competition

Correct answer: C

Rationale: The correct answer is 'Commensalism.' In commensalism, one organism benefits from the relationship while the other is neither helped nor harmed. This type of symbiotic relationship is characterized by one organism deriving a benefit, such as food or shelter, without impacting the other organism in any significant way. Choice A, 'Mutualism,' is a symbiotic relationship in which both organisms benefit. Choice B, 'Parasitism,' is a symbiotic relationship in which one organism benefits at the expense of the other. Choice D, 'Competition,' refers to a relationship in which organisms compete for limited resources, with both being affected in terms of access to resources.

3. Which type of joint is found in the neck and allows for rotational movement?

• A. Hinge joint
• B. Pivot joint
• C. Ball and socket joint
• D. Saddle joint

Correct answer: B

Rationale: The correct answer is B: Pivot joint. A pivot joint, like the one found in the neck, allows for rotational movement, enabling the head to turn from side to side. Hinge joints (Choice A) allow movement in one plane like a door hinge and are not found in the neck. Ball and socket joints (Choice C) allow for a wide range of motion in multiple directions and are typically found in the hip and shoulder. Saddle joints (Choice D) allow for movement back and forth and side to side, like the thumb joint, but are not found in the neck.

4. _____ are very ancient people.

• A. Chinese
• B. The Greeks
• C. Romans
• D. Egyptians

Correct answer: A

Rationale: The correct answer is 'Chinese.' In the context of ancient civilizations, 'Chinese' is appropriately used to refer to a very ancient culture like the Shang dynasty (c. 1600–1046 BC) or the Zhou dynasty (1046–256 BC). The other choices ('The Greeks,' 'Romans,' and 'Egyptians') are also ancient civilizations, but they are not the best fit in the given sentence as they do not match the description of 'very ancient people.' The Greeks, Romans, and Egyptians are ancient too, but 'very ancient people' specifically points towards Chinese civilization during its early periods. Therefore, 'Chinese' is the most suitable option.

5. In a static fluid, pressure (P) at a depth (h) is governed by the hydrostatic equation:

• A. P = ρgh
• B. P = γh
• C. P = μgh
• D. P = bh

Correct answer: A

Rationale: The correct formula for the pressure at a certain depth in a fluid according to the hydrostatic equation is P = ρgh. Here, ρ represents the fluid's density, g is the gravitational acceleration, and h is the depth. This formula shows that pressure increases linearly with the density of the fluid, the acceleration due to gravity, and the depth. Choices B, C, and D are incorrect because they do not accurately represent the relationship between pressure, density, gravitational acceleration, and depth in a static fluid.
