1. Which of the following numbers is NOT divisible by 3?

• A. 105
• B. 141
• C. 273
• D. 810

Correct answer: D

Rationale: Rationale: To determine if a number is divisible by 3, we can check if the sum of its digits is divisible by 3. If the sum of the digits is divisible by 3, then the original number is also divisible by 3. A) 105: 1 + 0 + 5 = 6, which is divisible by 3. Therefore, 105 is divisible by 3. B) 141: 1 + 4 + 1 = 6, which is divisible by 3. Therefore, 141 is divisible by 3. C) 273: 2 + 7 + 3 = 12, which is divisible by 3. Therefore, 273 is divisible by 3. D) 810: 8 + 1 + 0 = 9, which is divisible by 3. Therefore, 810 is divisible by 3. Since all the

5. Which of the following is the main organ responsible for regulating blood pressure?

• A. Heart
• B. Kidneys
• C. Adrenal glands
• D. Pituitary gland

Correct answer: B

Rationale: Rationale: The kidneys play a crucial role in regulating blood pressure through various mechanisms. One of the key ways the kidneys regulate blood pressure is by controlling the volume of blood in the body. They do this by adjusting the amount of water and sodium excreted in the urine. The renin-angiotensin-aldosterone system, which is primarily controlled by the kidneys, also plays a significant role in blood pressure regulation. This system helps to maintain blood pressure by regulating blood volume and systemic vascular resistance. While the heart, adrenal glands, and pituitary gland are involved in various aspects of the cardiovascular and endocrine systems, the kidneys are the main organ responsible for regulating blood pressure.
