1. To which two systems does the urethra belong?

• A. Reproductive and endocrine
• B. Urinary and reproductive
• C. Endocrine and urinary
• D. Digestive and cardiovascular

Correct answer: B

Rationale: The urethra belongs to both the urinary and reproductive systems. In the urinary system, it functions as a passage for urine from the bladder to exit the body. In the reproductive system, it serves as a conduit for the expulsion of semen during ejaculation. Choice A is incorrect because the urethra is not part of the endocrine system. Choice C is also incorrect because the urethra is not primarily associated with the endocrine system. Choice D is incorrect as the urethra is not part of the digestive or cardiovascular systems.

2. What is the meaning of Diameter?

• A. The width of a structure
• B. The distance across the center of an object
• C. The height of an object
• D. The radius of a circle

Correct answer: B

Rationale: The correct answer is B. Diameter is defined as the distance across the center of an object, typically a circle. Choice A is incorrect because width refers to the measurement of something from side to side, not necessarily through the center. Choice C is incorrect because height is a measurement from top to bottom, not across the center. Choice D is incorrect because the radius of a circle is the distance from the center to any point on the circle's circumference, not the distance across the center.

3. HPV is likely to involve the ___________.

• A. skull and spine
• B. mucous membranes
• C. kidneys
• D. heart

Correct answer: B

Rationale: HPV, which stands for Human Papillomavirus, is a virus that commonly affects the skin and mucous membranes. It primarily targets the genital area but can also infect the mouth and throat through oral-genital contact. Therefore, the most likely involvement of HPV is with the mucous membranes, making option B the correct choice. Choices A, C, and D are incorrect because HPV does not typically affect the skull, spine, kidneys, or heart.

4. Which of the following is a colligative property of a solution?

• A. Freezing point depression
• B. Viscosity
• C. Surface tension
• D. Boiling point elevation

Correct answer: A

Rationale: A colligative property is a property that depends on the number of solute particles in a solution, not on the identity of the solute particles. Freezing point depression is one such property, where adding a solute to a solvent lowers the freezing point of the solution compared to the pure solvent. This phenomenon occurs because the presence of solute particles disrupts the formation of the regular crystal lattice structure, requiring a lower temperature for solidification to occur. Choices B, C, and D are not colligative properties. Viscosity and surface tension are not dependent on the number of solute particles but on intermolecular forces and molecular interactions. Boiling point elevation is another colligative property, but in this case, the question asked for a colligative property of a solution, making freezing point depression the correct answer.

5. What is the meaning of exacerbate?

• A. To lessen in intensity
• B. To make worse
• C. To neutralize
• D. To control

Correct answer: B

Rationale: The correct answer is B: 'To make worse.' Exacerbate means to worsen or make a situation, condition, or problem more severe or intense, not to lessen it. Therefore, if something exacerbates a situation, it means it makes it worse. Choices A, C, and D are incorrect because exacerbate does not mean to lessen in intensity, neutralize, or control the situation, but rather to worsen it.
