1. What is the periodic law?

• A. The statement that the properties of the elements are a periodic function of their atomic numbers.
• B. The statement that the elements can be arranged in a table in which elements with similar properties are grouped together
• C. The statement that the elements can be arranged in a table in which the atomic number of an element is equal to the number of protons in its nucleus
• D. The statement that the elements can be arranged in a table in which the atomic mass of an element is equal to the number of neutrons in its nucleus.

Correct answer: A

Rationale: The periodic law states that the properties of elements are a periodic function of their atomic numbers. This means that when elements are arranged in order of increasing atomic number, there is a periodic repetition of their properties. This forms the basis for the modern periodic table. Option B describes the periodic table itself, while options C and D do not accurately describe the periodic law.

2. What is the name for the hard, protective protein that makes up hair and nails?

• A. Collagen
• B. Keratin
• C. Elastin
• D. Fibrin

Correct answer: B

Rationale: The correct answer is B: Keratin. Keratin is the name for the hard, protective protein that makes up hair and nails. Collagen is a structural protein found in connective tissues, while elastin is a protein that allows tissues in the body to resume their shape after stretching. Fibrin is a protein involved in blood clotting. Understanding the different roles of these proteins can help in identifying the correct answer as keratin specifically pertains to hair and nails.

3. Katherine tells one of the staff, “I don’t have time to discuss the matter with you now. See me

• A. Smoothing
• B. Compromise
• C. Avoidance
• D. Restriction

Correct answer: B

Rationale: The correct answer is B: 'Compromise.' In this scenario, Katherine is willing to engage with the staff member but suggests they postpone the discussion to a later time. This demonstrates a willingness to find a middle ground or reach a mutual agreement, which aligns with the concept of compromise. 'Smoothing' involves downplaying differences to maintain harmony, 'Avoidance' is ignoring or postponing the issue altogether, and 'Restriction' refers to limiting the interaction or communication. Therefore, 'Compromise' best fits the situation where Katherine is open to discussing the matter at a more suitable time.

4. What is the process of breaking down proteins into amino acids called?

• A. Proteolysis
• B. Lipolysis
• C. Carbohydrate catabolism
• D. Nucleic acid catabolism

Correct answer: A

Rationale: Rationale: Proteolysis is the process of breaking down proteins into amino acids. Lipolysis is the breakdown of fats into fatty acids and glycerol, not proteins. Carbohydrate catabolism involves the breakdown of carbohydrates into glucose for energy production. Nucleic acid catabolism is the breakdown of nucleic acids into nucleotides. In this context, the specific process of breaking down proteins into amino acids is best described by proteolysis.

5. An IV drip delivers 40 drops per minute, each containing 1mg of medication. How many milligrams are administered in 3 hours (180 minutes)?

• A. 360mg
• B. 720mg
• C. 7,200mg
• D. 14,400mg

Correct answer: C

Rationale: Rationale: In this scenario, we first calculated the total number of drops administered in 3 hours by multiplying the drops per minute by the total number of minutes. Then, we converted the drops to milligrams by multiplying the total drops by the amount of medication in each drop. This method ensures an accurate calculation of the total amount of medication administered over the given time period.

6. A car skids on a wet road. What is the main force preventing the car from stopping?

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

Correct answer: A

Rationale: Friction opposes the motion of the car, trying to bring it to a stop. However, due to the wet surface, the friction force is not enough to overcome the car's inertia.
