1. Which blood type is considered a universal donor?

• A. A
• B. B
• C. AB
• D. O

Correct answer: D

Rationale: Blood type O is considered the universal donor because individuals with type O blood can donate red blood cells to individuals with any ABO blood type (A, B, AB, or O) without causing an adverse reaction. Type O blood lacks A or B antigens on the surface of red blood cells, minimizing the risk of an immune response when transfused into individuals with different blood types. Therefore, type O blood is in high demand for blood transfusions in emergency situations when the recipient's blood type is unknown or when there is a shortage of specific blood types. Choices A, B, and AB are not considered universal donors. Individuals with blood types A, B, or AB can only donate to individuals with compatible blood types to avoid adverse reactions since they have A and/or B antigens on the surface of their red blood cells, making them incompatible with all blood types.

2. Which of the following occurred first in Alexander Graham Bell's life?

• A. Helped found the National Geographic Society.
• B. Developed a metal detector.
• C. Moved to Canada.
• D. Invented the telephone.

Correct answer: C

Rationale: Alexander Graham Bell moved to Canada early in his life, before inventing the telephone and developing other technologies. Choice A is incorrect because Bell did not help found the National Geographic Society; this happened years after his major inventions. Choice B is incorrect because Bell developed a metal detector after inventing the telephone. Choice D is incorrect because Bell invented the telephone after moving to Canada.

3. Which of the following processes describes the conversion of glucose to pyruvic acid during glycolysis?

• A. Glycogenesis
• B. Glycolysis
• C. Glycogenolysis
• D. Gluconeogenesis

Correct answer: B

Rationale: The correct answer is B: Glycolysis. Glycolysis is the metabolic pathway where glucose is broken down to produce pyruvic acid and ATP, generating energy in the form of ATP. Glycogenesis (choice A) is the process of glycogen synthesis, Glycogenolysis (choice C) is the breakdown of glycogen to release glucose, and Gluconeogenesis (choice D) is the synthesis of glucose from non-carbohydrate sources. Therefore, during glycolysis, glucose is converted into pyruvic acid, which is a crucial step in energy production.

4. Sarah is hosting a brunch for a baby shower and knows that several of the guests are strict vegans. She wants to make sure she prepares certain foods correctly to ensure all her guests have something to eat. In particular, she is looking for recipes for banana bread and blueberry muffins. Which chapter of the cookbook should she consult?

• A. Chapter I
• B. Chapter II
• C. Chapter IV
• D. Chapter V

Correct answer: B

Rationale: Chapter II typically focuses on baking and sweet treats, which would likely include recipes for banana bread and blueberry muffins. Sarah should consult this chapter for vegan-friendly versions of these recipes that will cater to her strict vegan guests. Choice A, Chapter I, primarily covers yeast breads, not the specific recipes Sarah is looking for. Choice C, Chapter IV, focuses on elegant, easy entrees, which are not relevant to the sweet treats Sarah wants. Choice D, Chapter V, covers delicious desserts and drinks, but it does not specifically mention the items Sarah is interested in, making it less likely to contain the recipes she needs.

5. The metric system is based on what concept?

• A. Multiplication
• B. Powers of 10
• C. Addition
• D. Subtraction

Correct answer: B

Rationale: The metric system is based on powers of 10. This means that units within the system are related by factors of 10, making conversions straightforward by simply shifting the decimal point. The system's simplicity and consistency are derived from this fundamental concept. Choices A, C, and D are incorrect because the metric system's foundation lies in the consistent relationship between units through powers of 10, not through basic arithmetic operations like multiplication, addition, or subtraction.
