1. What do ligaments connect?

• A. Muscle to muscle
• B. Bone to bone
• C. Bone to muscle
• D. Muscle to tendon

Correct answer: B

Rationale: Ligaments are fibrous connective tissues that connect bone to bone, providing stability and support to joints. They help prevent excessive movement in the joints and maintain proper alignment between bones during movement. Ligaments are not directly involved in connecting muscle to muscle, bone to muscle, or muscle to tendon. Choice A is incorrect because ligaments do not connect muscle to muscle. Choice C is incorrect as ligaments do not connect bone to muscle. Choice D is incorrect as ligaments do not connect muscle to tendon.

2. Which method is most suitable for measuring the volume of a cube?

• A. Triple beam balance
• B. Measuring wheel and mathematical formula
• C. Graduated cylinder
• D. Measuring wheel

Correct answer: B

Rationale: The correct answer is B. To measure the volume of a cube, you need to use a mathematical formula that takes into account the dimensions of the cube, specifically the length of its sides. Using a measuring wheel alone or a triple beam balance is not suitable for determining the volume of a cube. A graduated cylinder is used to measure the volume of liquids, not geometric solids like cubes.

3. Which of the following is not a type of muscle tissue?

• A. Skeletal
• B. Smooth
• C. Cardiac
• D. Adipose

Correct answer: D

Rationale: The correct answer is D, Adipose. Adipose tissue is a type of connective tissue that stores fat, not muscle tissue. Skeletal, smooth, and cardiac are all types of muscle tissues found in the body. Skeletal muscle tissue is responsible for voluntary movements and is attached to bones. Smooth muscle tissue is found in the walls of hollow organs and blood vessels, responsible for involuntary movements. Cardiac muscle tissue is found in the heart and is responsible for pumping blood throughout the body. Adipose tissue, on the other hand, primarily functions as a storage site for energy in the form of fat.

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

• A. Epididymis
• B. Vas deferens
• C. Seminal vesicle
• D. Cowper's gland

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.

5. What is the SI unit of measurement for acceleration?

• A. Meters per second (m/s)
• B. Newton (N)
• C. Meters (m)
• D. Meters per second squared (m/s²)

Correct answer: D

Rationale: The SI unit of measurement for acceleration is meters per second squared (m/s²). Acceleration is defined as the rate of change of velocity over time. It is a vector quantity with dimensions of length per time squared. Meters per second squared (m/s²) represents the change in velocity (meters per second) over a specific time interval (seconds) squared. Choice A, meters per second (m/s), represents velocity, not acceleration. Choice B, Newton (N), is the unit of force. Choice C, Meters (m), represents only distance, not acceleration. Therefore, the correct unit for acceleration is meters per second squared (m/s²).
