1. What is the function of the Vas Deferens?

• A. Produces fluid to increase sperm mobility
• B. Site where the egg matures
• C. Helps control urine flow
• D. Connects each testis to the urethra

Correct answer: D

Rationale: The vas deferens is a duct that connects each testis to the urethra, allowing the transport of sperm. Choice A is incorrect because the vas deferens does not produce fluid to increase sperm mobility. Choice B is incorrect as the vas deferens is not a site for egg maturation. Choice C is incorrect as the vas deferens does not help control urine flow, its primary role is in the transport of sperm.

2. What is the formula to calculate kinetic energy?

• A. Kinetic Energy = Mass × Velocity
• B. Kinetic Energy = Force × Distance
• C. Kinetic Energy = Power × Time
• D. Kinetic Energy = Potential Energy ÷ Time

Correct answer: A

Rationale: Kinetic energy is the energy an object possesses due to its motion. The formula to calculate kinetic energy is KE = 0.5 × mass × velocity^2, which can also be written as KE = mass × (velocity)^2. Therefore, the correct formula is Kinetic Energy = Mass × Velocity. Choice B is incorrect because it represents the work formula. Choice C is incorrect as it represents the formula for work done. Choice D is incorrect as it does not accurately represent the formula for calculating kinetic energy.

3. Where is fat primarily digested, and where is protein primarily digested?

• A. Mouth; stomach
• B. Stomach; small intestine
• C. Small intestine; small intestine
• D. Small intestine; stomach

Correct answer: B

Rationale: The correct answer is B. Fats are primarily digested in the small intestine, where bile from the liver emulsifies fats for enzymatic digestion. The small intestine is where most of the absorption of nutrients occurs. Proteins, on the other hand, are mainly digested in the stomach by the enzyme pepsin under acidic conditions. The stomach's acidic environment helps denature proteins, making them more accessible to pepsin for digestion. Choices A, C, and D are incorrect because they do not accurately reflect the primary sites of fat and protein digestion in the human digestive system.

4. What is the waste product of protein digestion?

• A. Glucose
• B. Amino acids
• C. Fatty acids
• D. Ammonia

Correct answer: D

Rationale: The waste product of protein digestion is ammonia. Protein digestion breaks down proteins into amino acids, and during this process, ammonia is produced. Ammonia is toxic and needs to be converted into urea in the liver for excretion via urine. Glucose is a product of carbohydrate digestion, amino acids are building blocks of proteins, and fatty acids are the end products of fat digestion. Therefore, the correct answer is ammonia.

5. 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.
