1. Which property of a substance resists a change in its shape?

• A. Density
• B. Mass
• C. Inertia
• D. Elasticity

Correct answer: D

Rationale: Elasticity refers to a material's ability to resist deformation and return to its original shape after stress is applied. It is the property that resists a change in shape. Density is the mass per unit volume of a substance. Mass is the amount of matter in an object, while inertia is the tendency of an object to resist changes in its state of motion. Viscosity, not mentioned in the question, is the resistance of a fluid to flow, not shape change.

2. In which position allows access to the stomach?

• A. Medial
• B. Prone
• C. Superficial
• D. Supine

Correct answer: B

Rationale: The question now specifies the need for a position that allows access to the stomach. The correct answer is 'B: Prone.' In the prone position, the patient lies face down, which facilitates access to the stomach for various procedures or examinations. Choice A, 'Medial,' refers to a direction rather than a patient position. Choice C, 'Superficial,' describes a superficial depth rather than a patient position. Choice D, 'Supine,' is a position where the patient lies face up, which does not provide easy access to the stomach.

3. A large geographic area characterized by similar climate, plants, and animals is called a:

• A. Population
• B. Community
• C. Biome
• D. Ecosystem

Correct answer: C

Rationale: A) Population refers to a group of individuals of the same species living in a specific area. B) Community refers to all the populations of different species living and interacting in a particular area. C) Biome is a large geographic area characterized by similar climate, plants, and animals. Biomes are defined by factors such as temperature, precipitation, and vegetation types. D) Ecosystem refers to a community of living organisms interacting with each other and their physical environment. An ecosystem can be part of a biome.

4. What is the anatomical term for the back of the body? Example: Shoulder blade.

• A. Anterior
• B. Superior
• C. Posterior
• D. Inferior

Correct answer: C

Rationale: The correct answer is C: Posterior. 'Posterior' is the anatomical term that refers to the back of the body. It is the opposite of 'anterior,' which refers to the front of the body. 'Superior' typically describes a structure that is positioned above another structure, while 'inferior' refers to a structure that is below another. In this case, the term 'posterior' specifically indicates the back of the body, making it the most appropriate choice among the options provided.

5. What is the relationship between the frequency and period of a wave?

• A. They are unrelated
• B. Frequency = Period
• C. Frequency = 1/Period
• D. Period = 1/Frequency

Correct answer: D

Rationale: The correct relationship between frequency and period of a wave is that Period = 1/Frequency. This relationship indicates that the period of a wave is the reciprocal of its frequency. Frequency refers to the number of complete cycles of a wave occurring in a unit of time, while the period is the time taken for one complete cycle of the wave to occur. As frequency and period are inversely related, the correct formula to express this relationship is Period = 1/Frequency. Choice A is incorrect as frequency and period are related. Choice B is incorrect as frequency and period are not equal. Choice C is incorrect as it suggests that frequency is directly proportional to period, which is not the case.
