1. What is the name of the condition characterized by swelling caused by a buildup of lymph fluid?

• A. Anemia
• B. Edema
• C. Hypertension
• D. Diabetes

Correct answer: B

Rationale: Edema is the condition characterized by swelling caused by a buildup of lymph fluid. It occurs when excess fluid is trapped in the body's tissues. Anemia (A) is a condition characterized by a lack of healthy red blood cells, leading to a reduced ability to carry oxygen in the blood. Hypertension (C) is high blood pressure, a condition where the force of the blood against the artery walls is too high. Diabetes (D) is a condition characterized by high blood sugar levels, either due to insufficient insulin production or the body's resistance to insulin, leading to various complications.

2. Which term refers to a position toward the head? Example: The hand is part of the superior extremity.

• A. Superior
• B. Inferior
• C. Medial
• D. Lateral

Correct answer: A

Rationale: The correct answer is 'Superior.' 'Superior' refers to a position toward the head, while 'inferior' is the term for a position toward the feet. In the given example, the hand belongs to the superior extremity, which includes structures closer to the head. 'Inferior' is incorrect as it refers to a position away from the head or toward the feet. 'Medial' describes a position closer to the midline of the body, while 'lateral' refers to a position farther away from the midline.

3. According to the Cahn-Ingold-Prelog (CIP) ranking system, which functional group has the highest priority?

• A. Alcohol (OH)
• B. Aldehyde (CHO)
• C. Carboxylic Acid (COOH)
• D. Amine (NH2)

Correct answer: C

Rationale: In the Cahn-Ingold-Prelog (CIP) ranking system, functional groups are prioritized based on the atomic number of the atoms directly attached to the functional group. Carboxylic acid (COOH) holds the highest priority as the carbon atom is directly bonded to two oxygen atoms, which have higher atomic numbers compared to carbon, hydrogen, or nitrogen. The higher the atomic number of the attached atoms, the higher the priority of the functional group in the CIP ranking system. Therefore, choices A, B, and D are incorrect as they have lower atomic numbers in the atoms directly attached to them, making them lower in priority according to the CIP system.

4. What is the main factor affecting the acceleration of a ball rolling down an inclined plane?

• A. The material of the ball
• B. The angle of the incline
• C. The air resistance
• D. The ball's initial velocity

Correct answer: B

Rationale: The main factor affecting the acceleration of a ball rolling down an inclined plane is the angle of the incline. The steeper the incline, the greater the component of the gravitational force acting parallel to the incline, leading to a higher acceleration of the ball. While the material of the ball, air resistance, and the ball's initial velocity may have some influence on the motion, the angle of the incline is the primary factor determining acceleration in this scenario. The material of the ball does not significantly affect its acceleration on the incline unless it impacts the friction with the surface. Air resistance plays a minor role in the acceleration of the ball compared to the gravitational force. The ball's initial velocity affects the speed at the start but does not influence the acceleration down the incline.

5. What is the scientific term for a muscle that helps another muscle perform its action?

• A. Agonist
• B. Antagonist
• C. Synergist
• D. Fixator

Correct answer: C

Rationale: A synergist is a muscle that assists the agonist, the primary muscle responsible for a specific movement, in performing that movement. Synergists stabilize joints and provide additional support to the prime mover muscle, enhancing the efficiency and effectiveness of the movement. Choice A, Agonist, refers to the muscle primarily responsible for a specific movement. Choice B, Antagonist, refers to a muscle that opposes the action of the agonist. Choice D, Fixator, refers to a muscle that stabilizes the origin of the prime mover muscle, maintaining the desired position during movement.
