1. What does the term 'counterfeit' mean?

• A. Real
• B. Fake
• C. Accurate
• D. Honest

Correct answer: B

Rationale: The correct answer is B: 'Fake.' Counterfeit refers to something that is not genuine or a copy made to deceive. Choice A, 'Real,' is incorrect because counterfeit items are not real. Choice C, 'Accurate,' is incorrect as counterfeit implies inaccuracy. Choice D, 'Honest,' is incorrect as counterfeit items are deceptive and not honest.

2. Which of the following is true of the Krebs cycle?

• A. It is a redox reaction involving proteins produced during glycolysis
• B. It is a redox reaction involving sugars produced during glycolysis
• C. Protons are passed along a gradient to produce ATP
• D. It is also known as the glycolic acid cycle

Correct answer: B

Rationale: The Krebs cycle, also known as the citric acid cycle, involves a series of redox reactions that occur in the mitochondria. The cycle begins with the oxidation of acetyl CoA, which is derived from the breakdown of sugars produced during glycolysis. These sugars are broken down further in the Krebs cycle to produce ATP and reduce electron carriers such as NADH and FADH2. The cycle does not involve proteins produced during glycolysis. Protons are not passed along a gradient to produce ATP directly in the Krebs cycle; rather, they are used in the electron transport chain to generate ATP. The Krebs cycle is not known as the glycolic acid cycle; glycolysis is the metabolic pathway that produces pyruvate from glucose.

3. When a die is rolled, what is the probability of rolling an odd number?

• A. 16.67%
• B. 33.33%
• C. 75%
• D. 50%

Correct answer: D

Rationale: When a die is rolled, there are 3 odd numbers (1, 3, 5) out of a total of 6 possible outcomes. The probability of rolling an odd number is calculated by dividing the number of favorable outcomes (3) by the total number of outcomes (6), resulting in a probability of 3/6 or 50%. Therefore, the correct answer is D. Choices A, B, and C are incorrect because they do not reflect the correct probability calculation for rolling an odd number on a standard six-sided die.

4. Which vitamin is important for blood clotting?

• A. Vitamin C
• B. Vitamin K
• C. Vitamin A
• D. Vitamin D

Correct answer: B

Rationale: Vitamin K is crucial for the synthesis of proteins involved in blood clotting, aiding in the prevention of excessive bleeding. Without sufficient Vitamin K, the blood may not clot properly, leading to an increased risk of bleeding and other related complications. Vitamin C is essential for collagen synthesis and the immune system, not specifically for blood clotting. Vitamin A is important for vision and immune function. Vitamin D plays a role in calcium absorption and bone health, but it is not directly linked to blood clotting.

5. An overt symptom is ___________.

• A. dangerous
• B. hidden
• C. obvious
• D. controlled

Correct answer: C

Rationale: An overt symptom is a symptom that is easily noticeable or observable. It is not hidden or controlled, but rather overt and easily seen or identified by others. Therefore, the correct answer is C, 'obvious.' 'Dangerous' (choice A) does not describe the visibility of a symptom but rather its potential harm. 'Hidden' (choice B) is the opposite of overt, meaning not easily visible. 'Controlled' (choice D) does not relate to the visibility of a symptom but rather implies regulation or management.'
