1. Which of the following factors does not strengthen a scientific argument?

• A. Lack of bias
• B. Extensive use of qualitative research and data
• C. Able to be reproduced and repeated by others
• D. Withstands the test of time

Correct answer: B

Rationale: The correct answer is B. While qualitative data can provide valuable insights, it does not inherently strengthen a scientific argument to the same extent as quantitative data. Quantitative data is generally more precise, measurable, and easier to verify, making it a stronger basis for scientific arguments. Choices A, C, and D all contribute to strengthening a scientific argument. Lack of bias ensures objectivity and reliability, reproducibility by others validates the findings, and standing the test of time indicates the enduring validity and reliability of the argument.

2. Which of the following is NOT a risk factor for developing atherosclerosis?

• A. High blood pressure
• B. High levels of LDL cholesterol
• C. Regular physical activity
• D. Smoking

Correct answer: C

Rationale: Regular physical activity is not a risk factor for developing atherosclerosis; in fact, it is associated with a reduced risk. High blood pressure, high levels of LDL cholesterol, and smoking are all known risk factors for atherosclerosis. Regular physical activity plays a crucial role in improving cardiovascular health, reducing the risk of atherosclerosis, and maintaining overall well-being. Therefore, the correct answer is regular physical activity (choice C).

3. What is the medical term for an ingrown hair?

• A. Folliculitis
• B. Hirsutism
• C. Pseudofolliculitis Barbae
• D. Alopecia

Correct answer: A

Rationale: The correct answer is A, Folliculitis. Folliculitis is the medical term for the inflammation of hair follicles, which can be caused by ingrown hairs. Hirsutism refers to excessive hair growth, pseudofolliculitis barbae is a condition where shaving causes ingrown hairs, and alopecia is hair loss. Therefore, choices B, C, and D are incorrect as they do not specifically refer to ingrown hairs.

4. What is the term for the balanced equation that represents a chemical reaction?

• A. Hypothesis
• B. Chemical formula
• C. Balanced equation
• D. Reaction mechanism

Correct answer: C

Rationale: The correct answer is C - 'Balanced equation'. A balanced equation is a representation of a chemical reaction that shows the reactants, products, and their stoichiometric coefficients. It ensures that the number of atoms of each element is equal on both sides of the equation, following the law of conservation of mass. Choice A, 'Hypothesis', is incorrect as it refers to a proposed explanation based on limited evidence as a starting point for further investigation. Choice B, 'Chemical formula', is incorrect as it represents the composition of a compound using symbols and subscripts. Choice D, 'Reaction mechanism', is incorrect as it describes the step-by-step process by which a chemical reaction occurs, not just the overall representation of the reaction itself.

5. Which blood vessels transport blood from the capillaries back to the heart?

• A. Arterioles
• B. Veins
• C. Venules
• D. Capillaries

Correct answer: B

Rationale: Veins are the correct answer as they are the blood vessels that carry blood from the capillaries back to the heart. Veins have thinner walls compared to arteries and contain valves to prevent blood from flowing backward. This transport of blood from the capillaries to the heart is essential for the circulatory system to maintain proper blood flow and oxygenation levels. Arterioles are small branches of arteries that lead to capillaries, not vessels that transport blood back to the heart. Venules are small vessels that collect blood from capillaries and lead to veins. Capillaries are the smallest blood vessels where the exchange of gases and nutrients occurs between blood and tissues, not vessels that transport blood back to the heart.
