1. What is the number of students who said their favorite color is blue if 35% of 100 students chose blue as their favorite color?

• A. 35
• B. 25
• C. 20
• D. 10

Correct answer: A

Rationale: To find the number of students who said their favorite color is blue, we calculate 35% of 100, which is (35/100) * 100 = 35. Therefore, 35 students said their favorite color is blue. Choice B is incorrect because it represents the percentage of students who chose red. Choice C is incorrect as it represents the percentage of students who chose green. Choice D is incorrect as it represents the percentage of students who chose yellow.

2. What is the name of the muscular ring that controls the passage of food from the esophagus to the stomach?

• A. Pyloric sphincter
• B. Cardiac sphincter
• C. Ileocecal valve
• D. Sphincter of Oddi

Correct answer: B

Rationale: The correct answer is the Cardiac sphincter (lower esophageal sphincter). It is situated at the junction of the esophagus and the stomach, controlling the passage of food into the stomach. The cardiac sphincter opens and closes to regulate the flow of food and prevent reflux. The pyloric sphincter, on the other hand, is located between the stomach and the small intestine, not the esophagus and stomach. The ileocecal valve is positioned between the small and large intestines, while the Sphincter of Oddi is found in the duodenum, not between the esophagus and stomach.

3. What is the square root of 1296?

• A. 24
• B. 36
• C. 31
• D. 12

Correct answer: B

Rationale: The square root of 1296 is 36 because 36 multiplied by 36 equals 1296. Therefore, the correct answer is 36. Choices A, C, and D are incorrect. A (24) is not the square root of 1296 because 24 multiplied by 24 is 576, not 1296. C (31) is also incorrect as 31 multiplied by 31 is 961, not 1296. D (12) is not the square root of 1296 as 12 multiplied by 12 equals 144, not 1296.

4. Which of the following structures acts like a funnel by delivering urine from the millions of collecting tubules to the ureters?

• A. The renal pelvis
• B. The renal cortex
• C. The renal medulla
• D. Bowman's capsule

Correct answer: A

Rationale: The correct answer is A: The renal pelvis. The renal pelvis serves as a reservoir for urine collected from the kidney's numerous collecting tubules, funneling it into the ureters for transport to the bladder. The renal cortex is the outer region of the kidney involved in filtration, while the renal medulla is the inner region responsible for concentrating urine. Bowman's capsule is part of the nephron and is involved in the initial filtration of blood in the kidney, not in funneling urine to the ureters.

5. Which of the following terms means close to the trunk of the body?

• A. Superficial
• B. Sagittal
• C. Proximal
• D. Distal

Correct answer: C

Rationale: The term 'proximal' means situated close to the point of attachment or the center of the body, such as close to the trunk. In anatomical terms, proximal is used to describe locations that are closer to the body's center or point of reference. 'Superficial' refers to something situated near the surface, 'sagittal' refers to a plane that divides the body into left and right portions, and 'distal' refers to a position away from the center or point of reference. Therefore, 'proximal' is the correct term to indicate a position close to the trunk of the body.
