Anatomy
1. Which of the following hormones helps regulate blood pressure by affecting kidney function?
- A. Insulin
- B. Testosterone
- C. Renin
- D. Estrogen
Correct answer: C
Rationale: The correct answer is C: Renin. Renin is an enzyme produced by the kidneys that plays a crucial role in regulating blood pressure. Renin helps control blood pressure by initiating a series of reactions that ultimately lead to the production of angiotensin, a hormone that constricts blood vessels and increases blood pressure. Insulin is a hormone that regulates blood sugar levels, not blood pressure. Testosterone and estrogen are sex hormones that do not have a direct impact on kidney function or blood pressure regulation. Therefore, the correct hormone that helps regulate blood pressure by affecting kidney function is Renin.
2. The final sentence suggests that public discourse about AI should focus on
- A. Celebrating the achievements of AI and promoting its widespread adoption in all sectors.
- B. Criticizing the ethical shortcomings of existing AI systems and demanding stricter regulations.
- C. Engaging in open and informed discussions about the potential benefits, risks, and responsible development of AI.
- D. Focusing solely on the technical challenges of AI development and leaving ethical considerations to experts.
Correct answer: C
Rationale: The emphasis on "ongoing public discourse" and "the future of AI in society" suggests a call for open discussions and collective responsibility, aligning with C.
3. Which of the following is NOT typically found in healthy urine?
- A. Urea
- B. Glucose
- C. Creatinine
- D. Electrolytes
Correct answer: B
Rationale: Glucose is NOT typically found in healthy urine because the kidneys filter glucose from the blood, and any excess is excreted in the urine. In healthy individuals, the renal threshold for glucose reabsorption is low, so glucose should not be present in significant amounts in urine. On the other hand, urea, creatinine, and electrolytes are all normal components of urine. Urea is a waste product of protein metabolism, creatinine is a waste product of muscle metabolism, and electrolytes like sodium and potassium are essential for various bodily functions and are excreted in urine. Therefore, option B is the correct answer as glucose is not typically found in healthy urine.
4. A reaction between an acid and a base is known as:
- A. Precipitation
- B. Neutralization
- C. Oxidation-reduction
- D. Photolysis
Correct answer: B
Rationale: When an acid and a base react, they neutralize each other's properties
5. Which sentence uses the past perfect tense correctly?
- A. By the time I arrived, the party had already begun.
- B. I wish I had studied harder for the exam.
- C. We will have finished the project by Monday.
- D. She had been waiting for hours before he finally showed up.
Correct answer: A
Rationale: Option A expresses an action ("party began") completed before another past action ("I arrived").
6. What effect does doubling the net force applied to an object have on its acceleration, assuming mass remains constant?
- A. Acceleration doubles
- B. Acceleration is halved
- C. Acceleration remains the same
- D. Acceleration quadruples
Correct answer: a
Rationale: According to Newton's second law (F = ma), if mass remains constant and force doubles, acceleration also doubles.
