1. A car is traveling on a curved road. What force keeps the car moving along the curved path?

• A. Gravitational force
• B. Normal force from the road
• C. Air resistance
• D. Friction between the tires and the road

Correct answer: D

Rationale: In this case, static friction acts between the tires and the road, providing the centripetal force required to keep the car moving in a circle even though it's traveling in a straight line relative to the ground.

2. What type of bond involves the complete transfer of electrons between atoms?

• A. Covalent bond
• B. Ionic bond
• C. Metallic bond
• D. Hydrogen bond

Correct answer: B

Rationale: Ionic bond - Electrons are completely transferred from one atom to another, creating cations and anions with strong electrostatic attraction.

3. Which statement BEST summarizes the author's perspective on bioremediation for plastic pollution?

• A. It is the only viable solution to the problem and should be prioritized.
• B. It is a promising approach but requires further research and development.
• C. It is less effective than traditional methods and poses environmental risks.
• D. It is irrelevant to the problem and will not make a significant impact.

Correct answer: B

Rationale: The passage acknowledges the potential of bioremediation while highlighting the need for further research, indicating a balanced perspective.

4. Pseudostratified columnar epithelium

• A. Skeletal muscle
• B. Bony skeleton
• C. External ears
• D. Bloodstream

Correct answer: C

Rationale: The correct answer is C: External ears. Pseudostratified columnar epithelium is a type of epithelial tissue found in the respiratory tract, where it appears to be stratified but all cells are anchored to the basement membrane. The external ears are lined with pseudostratified columnar epithelium to help protect and support the structures of the ear canal. Skeletal muscle (A) is a type of muscle tissue, bony skeleton (B) refers to bones, and bloodstream (D) is a system for blood circulation, which are not related to pseudostratified columnar epithelium.

5. A bar graph shows the number of patients admitted to the ER each day for a week. How do you determine the day with the highest number of admissions?

• A. Find the tallest bar in the graph.
• B. Compare the heights of all bars.
• C. Calculate the average number of admissions per day.
• D. Subtract the lowest number of admissions from the highest.

Correct answer: A

Rationale: The best approach is to find the tallest bar

6. The external body covering, providing protection and contributing to temperature regulation, is composed of:

• A. Muscle tissue
• B. Epithelial tissue (skin)
• C. Bone marrow
• D. Cartilage

Correct answer: B

Rationale: The correct answer is B: Epithelial tissue (skin). The skin is the external body covering that provides protection against physical, chemical, and biological factors. It also plays a crucial role in regulating body temperature by controlling heat exchange with the environment through processes like sweating and blood vessel constriction or dilation. Muscle tissue (option A) is responsible for movement, bone marrow (option C) produces blood cells, and cartilage (option D) is a type of connective tissue found in joints. Therefore, epithelial tissue (skin) is the most suitable option as it directly addresses the functions of the external body covering.
