1. Which of the following is a characteristic of a solution with a high viscosity?

• A. It flows easily
• B. It has a low resistance to flow
• C. It has a high resistance to flow
• D. It does not mix with other liquids

Correct answer: c

Rationale: Solutions with high viscosity have a high resistance to flow. The other choices do not accurately describe high viscosity.

2. Which additional information would be MOST relevant to the passage's argument?

• A. A detailed biography of a historical figure with no analysis of their impact on society.
• B. A timeline of technological advancements throughout history with no connection to social consequences.
• C. A case study of how historical knowledge informed the development of a successful solution to a contemporary problem.
• D. A statistical analysis of economic trends without any reference to historical events or context.

Correct answer: C

Rationale: Choice C aligns with the passage's theme by demonstrating how historical knowledge directly impacted a contemporary solution, further supporting the argument for history's value.

3. Which of the following is the primary function of the lymphatic system?

• A. Transporting oxygen and nutrients to cells
• B. Carrying waste products away from tissues
• C. Regulating body temperature
• D. Producing red blood cells

Correct answer: B

Rationale: The correct answer is B: 'Carrying waste products away from tissues.' The primary function of the lymphatic system is to collect excess fluid from tissues and return it to the bloodstream, while also transporting waste products, pathogens, and cellular debris away from tissues to be filtered and eliminated. This helps maintain fluid balance in the body and supports the immune system by removing harmful substances. Options A, C, and D do not accurately describe the primary function of the lymphatic system, making them incorrect choices.

4. Which type of wave motion occurs when particles move perpendicular to the direction of wave propagation?

• A. Transverse waves
• B. Longitudinal waves
• C. Electromagnetic waves
• D. Surface waves

Correct answer: A

Rationale: Transverse waves are characterized by particles moving perpendicular to the direction of wave propagation. In these waves, the oscillations of the particles are perpendicular to the direction of energy transfer. Longitudinal waves, on the other hand, have particles that move parallel to the direction of wave propagation. Electromagnetic waves are a type of transverse wave that do not require a medium for propagation. Surface waves are a combination of both longitudinal and transverse motions and occur at the interface between two different mediums.

5. he adrenal cortex produces a group of steroid hormones called corticosteroids. What is a MAJOR function of corticosteroids?

• A. Regulate insulin sensitivity and blood sugar levels
• B. Control blood pressure and electrolyte balance
• C. Stimulate the immune system and inflammatory response
• D. Promote growth and development during puberty

Correct answer: B

Rationale: The correct answer is B: 'Control blood pressure and electrolyte balance.' Corticosteroids, produced by the adrenal cortex, play a major role in regulating blood pressure and electrolyte balance in the body. These hormones, such as aldosterone, act on the kidneys to control the reabsorption of sodium and water, which in turn affects blood pressure and electrolyte levels. While corticosteroids can have effects on other physiological processes, their primary function is to regulate blood pressure and electrolyte balance, making option B the most appropriate choice in this context.

6. An IV drip delivers 40 drops per minute, each containing 1mg of medication. How many milligrams are administered in 3 hours (180 minutes)?

• A. 360mg
• B. 720mg
• C. 7,200mg
• D. 14,400mg

Correct answer: C

Rationale: Rationale: In this scenario, we first calculated the total number of drops administered in 3 hours by multiplying the drops per minute by the total number of minutes. Then, we converted the drops to milligrams by multiplying the total drops by the amount of medication in each drop. This method ensures an accurate calculation of the total amount of medication administered over the given time period.
