1. Where does fertilization of the egg by sperm typically occur?

• A. Ovary
• B. Fallopian tube
• C. Uterus
• D. Vagina

Correct answer: B

Rationale: Fertilization of the egg by sperm typically occurs in the fallopian tube. After ovulation, the egg is released from the ovary and travels through the fallopian tube, where it may encounter sperm for fertilization. The fallopian tube provides the ideal environment, including necessary nutrients and conditions, for fertilization to take place before the fertilized egg moves towards the uterus for implantation. Choices A, C, and D are incorrect because fertilization does not occur in the ovary, uterus, or vagina. The ovary releases the egg, the uterus is the site for implantation, and the vagina is part of the birth canal but not the typical site for fertilization.

2. Which muscle is voluntary, striated, and found attached to bones?

• A. Smooth muscle
• B. Skeletal muscle
• C. Cardiac muscle
• D. Epithelial muscle

Correct answer: B

Rationale: The correct answer is B, Skeletal muscle. Skeletal muscle is both voluntary and striated, as well as attached to bones, allowing for movement. Smooth muscle, on the other hand, is involuntary and typically found in the walls of internal organs, controlling functions like digestion. Cardiac muscle is also striated, but it is involuntary and specifically found in the heart, responsible for cardiac contractions to pump blood. 'Epithelial muscle' is an incorrect term; epithelial tissue is a type of tissue that forms the linings of various body surfaces and structures, not a muscle type.

3. What is the term for the process of converting a liquid into a gas at a temperature below its boiling point?

• A. Vaporization
• B. Evaporation
• C. Condensation
• D. Sublimation

Correct answer: B

Rationale: Evaporation is the correct term for the process of converting a liquid into a gas at a temperature below its boiling point. During evaporation, molecules of the liquid gain enough energy to escape into the gas phase, primarily occurring at the liquid's surface. Vaporization is a broader term that encompasses the conversion of a substance from a liquid or solid state to a gas, not specifically at temperatures below the boiling point. Condensation is the reverse process of evaporation, involving the conversion of a gas into a liquid. Sublimation, on the other hand, refers to the direct transition of a substance from the solid phase to the gas phase without passing through the liquid phase.

4. What is the role of bile in digestion?

• A. To break down carbohydrates
• B. To emulsify fats
• C. To neutralize stomach acid
• D. To absorb proteins

Correct answer: B

Rationale: Bile emulsifies fats, breaking them down into smaller droplets for easier digestion.

5. What type of force enables a car to take a sharp turn while moving in a circular path?

• A. Centripetal force
• B. Tension force
• C. Frictional force
• D. Gravitational force

Correct answer: A

Rationale: Centripetal force is the force that allows an object to move in a circular path. When a car takes a sharp turn, centripetal force acts towards the center of the circle, enabling the car to stay in the curved path. Tension force is transmitted through a string, rope, cable, or wire when pulled tight, and it is not directly related to a car's turning motion. Frictional force opposes motion and is not the primary force responsible for a car's ability to take a sharp turn. Gravitational force is the attraction between masses and does not directly influence a car's ability to maneuver in a curved path.
