1. What is the muscular tube that transports sperm from the testes to the urethra called?

Correct answer: B

Rationale: The correct answer is the vas deferens. It is the muscular tube responsible for carrying sperm from the testes to the urethra. After sperm is produced in the testes, it moves to the epididymis for maturation and storage. The seminal vesicle contributes fluid to semen, but it is not the tube that transports sperm. Cowper's gland also adds fluid to semen but is not involved in transporting sperm. Therefore, the vas deferens is the accurate choice for the muscular tube that transports sperm.

2. Which vitamin is essential for proper absorption of calcium and plays a role in lung function?

Correct answer: C

Rationale: The correct answer is Vitamin D. Vitamin D is crucial for the proper absorption of calcium in the intestines and is essential for maintaining lung function. It regulates calcium and phosphorus levels, crucial for healthy bones and teeth. Vitamin A is important for vision and immune function, not specifically for calcium absorption or lung function. Vitamin B12 is essential for nerve function and red blood cell production, not related to calcium absorption or lung function. Vitamin E is an antioxidant that helps protect cells from damage, but it is not directly involved in calcium absorption or lung function.

3. Which of the following structures in the cell is responsible for producing ATP?

Correct answer: C

Rationale: The correct answer is C, Mitochondria. Mitochondria are known as the powerhouse of the cell and are responsible for producing ATP, the primary energy currency of the cell through cellular respiration. Ribosomes (Choice A) are involved in protein synthesis, the nucleus (Choice B) stores genetic material and controls cell activities, and the endoplasmic reticulum (Choice D) plays a role in protein synthesis, lipid metabolism, and detoxification, but none of these structures are directly responsible for producing ATP.

4. Which form of energy is associated with the motion of an object?

Correct answer: A

Rationale: Kinetic energy is the form of energy associated with the motion of an object. When an object is in motion, it possesses kinetic energy due to its movement. Potential energy, on the other hand, is stored energy that an object has due to its position or condition. Thermal energy is related to heat, while electrical energy is associated with the flow of electric charge. In this case, the correct answer is kinetic energy as it directly correlates with the motion of an object.

5. Which of the following is NOT a function of the skeletal system?

Correct answer: D

Rationale: The skeletal system's primary functions include support and structure, protection of internal organs, movement facilitation, production of blood cells, and storage of minerals like calcium. Insulation of the body is not a function of the skeletal system. Insulation, typically involving fat under the skin, helps regulate body temperature but is not a direct function of the skeletal system. Choice B, the production of red blood cells, is a function of the skeletal system as it occurs in the bone marrow within the bones. Choices A and C are also correct functions of the skeletal system.
