1. What is Diffusion?

• A. Movement of materials from low concentration to high concentration
• B. Movement of materials from high concentration to low concentration
• C. Absorption of nutrients
• D. Breaking of materials

Correct answer: B

Rationale: Diffusion is the process where substances move from an area of high concentration to an area of low concentration. This movement occurs due to the random motion of particles and continues until equilibrium is reached. Choice A is incorrect because diffusion occurs down the concentration gradient, from high to low concentration, not from low to high concentration. Choice C is incorrect as it refers to the uptake of substances by cells, not the general process of diffusion. Choice D is incorrect as it does not accurately describe the process of diffusion; diffusion involves the movement of substances, not the breaking of materials.

2. Select the meaning of the underlined word in the following sentence. Apply the gel on the gingival margin around the selected teeth using the blunt-tipped applicator included in the package.

• A. Edge
• B. Grease
• C. Incisor
• D. Cavity

Correct answer: A

Rationale: In this context, the word 'margin' refers to the border or edge of the gums around the teeth. The gel is supposed to be applied on the gingival margin, which means on the edge or border of the gums near the selected teeth. Choice B, 'Grease,' is incorrect as it does not relate to the application of gel on the gums. Choice C, 'Incisor,' refers to a type of tooth and is unrelated to the context of applying gel on the gingival margin. Choice D, 'Cavity,' is also unrelated as it refers to a decayed area in a tooth and not the border of the gums.

3. What is another word for acrid?

• A. Bitter
• B. Smoky
• C. Nimble
• D. Severe

Correct answer: A

Rationale: Acrid is often used to describe a sharp, unpleasant smell or taste, which is synonymous with bitterness. The word 'bitter' closely relates to the strong and sharp sensation associated with acrid qualities. Choice B, 'Smoky,' does not capture the sharpness or unpleasantness associated with acrid, as it refers more to the presence of smoke. Choice C, 'Nimble,' and choice D, 'Severe,' are unrelated to the meaning of acrid and do not serve as synonyms in this context.

4. The voice box may be called the ______

• A. Pharynx
• B. Larynx
• C. Trachea
• D. Esophagus

Correct answer: B

Rationale: The correct term for the voice box is the larynx. The pharynx is part of the throat involved in swallowing and breathing but not the voice production. The trachea is the windpipe responsible for air passage, and the esophagus is the tube that carries food from the mouth to the stomach. Therefore, in this context, the larynx is the most appropriate term.

5. What is your “funny bone” actually?

• A. Humerus
• B. Ulnar nerve
• C. Carpal bone
• D. Biceps brachii

Correct answer: B

Rationale: Your 'funny bone' is actually your ulnar nerve, not a bone. The ulnar nerve runs along the inside part of your elbow and is easily bumped or compressed, leading to a tingling or slightly painful sensation that is commonly referred to as hitting your funny bone. The humerus (Choice A) is the long bone in your upper arm, the carpal bone (Choice C) is a bone in your wrist, and the biceps brachii (Choice D) is a muscle in your upper arm. Therefore, the correct answer is the ulnar nerve (Choice B).
