1. In aerobic respiration, how many ATP molecules are produced per molecule of FADH2?

• A. 1
• B. 2
• C. 3
• D. 4

Correct answer: B

Rationale: The correct answer is B: 2. During aerobic respiration, each molecule of FADH2 produces 2 ATP molecules. FADH2 enters the electron transport chain and contributes to the generation of ATP. Choice A (1), Choice C (3), and Choice D (4) are incorrect because FADH2 specifically yields 2 ATP molecules per molecule in the process of aerobic respiration.

2. What is the microscopic functional unit of the kidney responsible for filtering blood?

• A. Ureter
• B. Nephron
• C. Renal pelvis
• D. Bladder

Correct answer: B

Rationale: The nephron is the correct answer as it is the microscopic functional unit of the kidney responsible for filtering blood. It is composed of a renal corpuscle (glomerulus and Bowman's capsule) and a renal tubule. The other options, such as (A) Ureter, (C) Renal pelvis, and (D) Bladder, do not play a role in filtering blood within the kidney. The ureter is a tube that carries urine from the kidney to the bladder. The renal pelvis is a part of the kidney where urine collects before entering the ureter. The bladder is an organ that stores urine until it is excreted from the body.

3. Edema, characterized by swelling due to fluid buildup, can be a sign of:

• A. Heart failure
• B. Liver disease
• C. Lymphatic system dysfunction
• D. All of the above

Correct answer: D

Rationale: Edema is the swelling caused by fluid retention in the body tissues. It can indicate various underlying conditions. Heart failure can lead to fluid buildup due to the heart's ineffective pumping. Liver disease can cause edema by reducing protein production, leading to fluid leakage into tissues. Dysfunction of the lymphatic system can impair fluid drainage, contributing to edema. Therefore, all of the above conditions can manifest with edema, making the correct answer 'All of the above.' Choices A, B, and C are all valid causes of edema, making them incorrect when considered individually. Selecting 'All of the above' encompasses all the possible causes of edema.

4. Based on the scenario provided, which of the following inferences can be validly made?

• A. This director consistently produces unsuccessful movies.
• B. Movie reviews have no impact on the success of a film.
• C. The movie reviewers' assessments of the first movie were correct.
• D. The director's next movie will receive positive reviews.

Correct answer: C

Rationale: Choice C is the correct answer because the scenario indicates that the negative reviews of the first movie were accurate, as the subsequent poor performance of the movie aligns with the critics' assessments. Choices A and D are incorrect as the scenario only provides information about the first movie and its repercussions, not about the director's consistent performance or the future reception of their movies. Choice B is incorrect because the scenario clearly demonstrates that negative reviews had a significant impact on the movie's performance, contradicting the idea that movie reviews have no influence.

5. How will 0.80 be written as a percent?

• A. 40%
• B. 125%
• C. 90%
• D. 80%

Correct answer: D

Rationale: To convert a decimal to a percent, you multiply by 100. Therefore, 0.80 * 100 = 80%. The correct answer is D. Choice A (40%) is incorrect as 0.80 is not equivalent to 40%. Choice B (125%) is incorrect as it is greater than 100%. Choice C (90%) is incorrect as it does not reflect the correct conversion of 0.80 to a percent.
