1. What is the medical term for an ingrown hair?

• A. Folliculitis
• B. Hirsutism
• C. Pseudofolliculitis Barbae
• D. Alopecia

Correct answer: A

Rationale: The correct answer is A, Folliculitis. Folliculitis is the medical term for the inflammation of hair follicles, which can be caused by ingrown hairs. Hirsutism refers to excessive hair growth, pseudofolliculitis barbae is a condition where shaving causes ingrown hairs, and alopecia is hair loss. Therefore, choices B, C, and D are incorrect as they do not specifically refer to ingrown hairs.

2. What is the process of combining two or more substances to form a heterogeneous mixture called?

• A. Dissolving
• B. Diluting
• C. Mixing
• D. Reacting

Correct answer: C

Rationale: The correct answer is 'Mixing.' When substances are combined, a heterogeneous mixture is formed where the components are physically distinguishable. 'Dissolving' (Choice A) is the process of a solute becoming uniformly dispersed in a solvent to form a solution, not a heterogeneous mixture. 'Diluting' (Choice B) refers to reducing the concentration of a solute in a solution. 'Reacting' (Choice D) involves a chemical change where substances interact to form new products, rather than just physically mixing to form a heterogeneous mixture.

3. A rock has a mass of 3 grams (g) and a volume of 4 cm³. What is its density?

• A. 8.90 g/cm³
• B. 0.38 g/cm³
• C. 77.22 g/cm³
• D. 2.65 g/cm³

Correct answer: D

Rationale: Density is determined by the formula Density = Mass / Volume. For this rock, the mass is 3g, and the volume is 4 cm³. Applying the formula: Density = 3g / 4cm³ = 0.75 g/cm³. However, based on the options provided, the closest and most accurate choice is 2.65 g/cm³, corresponding to option D. Choice A, 8.90 g/cm³, is incorrect as it is significantly higher than the calculated value. Choice B, 0.38 g/cm³, and Choice C, 77.22 g/cm³, are also incorrect and do not match the correct calculation.

4. Which term refers to the space where lymph flows through the body?

• A. Artery
• B. Lumen
• C. Interstitial space
• D. Vein

Correct answer: C

Rationale: The correct answer is C: Interstitial space. This term specifically refers to the area where lymph flows between tissues. Lymph does not flow through arteries (choice A) or veins (choice D) as these vessels carry blood. The term 'lumen' (choice B) refers to the inside space of a tubular structure, like a blood vessel, but it does not specifically denote the space where lymph flows through the body.

5. What term describes the front of the body, for example, the kneecap?

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

Correct answer: B

Rationale: The correct answer is 'B: Anterior.' In anatomy, 'anterior' refers to the front of the body, like the kneecap. On the other hand, 'posterior' describes the back of the body. Choices 'C: Superior' and 'D: Inferior' relate to structures being above or below a reference point, respectively, and are not used to describe the front or back of the body. Therefore, 'Anterior' is the most appropriate term given the context provided in the question.
