1. What is the difference between polygenic inheritance and pleiotropy?

Correct answer: A

Rationale: Rationale: - Polygenic inheritance refers to the situation where a trait is influenced by multiple genes, each contributing a small effect to the phenotype. These traits often show continuous variation and are not easily categorized into discrete categories. - Pleiotropy, on the other hand, occurs when a single gene influences multiple, seemingly unrelated traits. This means that a mutation in one gene can lead to multiple phenotypic effects across different traits or characteristics. - Therefore, the key difference between polygenic inheritance and pleiotropy lies in the number of genes involved in influencing a trait (multiple genes in polygenic inheritance vs. one gene in pleiotropy) and the direction of influence (one trait affected by multiple genes in polygenic inheritance vs. multiple traits affected by one gene in pleiotropy).

2. Dietary fiber, although not fully digested by the body, plays a crucial role in digestion. What is one of the main benefits of consuming sufficient dietary fiber?

Correct answer: C

Rationale: Consuming sufficient dietary fiber promotes satiety and gut health. Fiber adds bulk to the diet, which helps you feel full and satisfied after meals, reducing overeating. Additionally, fiber helps regulate bowel movements by promoting healthy digestion and preventing constipation. It also feeds beneficial gut bacteria, supporting a healthy gut microbiome. While fiber does not provide energy like carbohydrates, it is essential for overall digestive health and can help prevent various chronic diseases.

3. Which statement accurately describes the Linnaean system of classification?

Correct answer: D

Rationale: Rationale: The Linnaean system of classification, developed by Carl Linnaeus, is based on a hierarchical ranking system where organisms are grouped into categories based on shared characteristics. This system organizes organisms into a hierarchy of increasingly specific categories, from broad to narrow, such as kingdom, phylum, class, order, family, genus, and species. This hierarchical approach allows for the systematic organization and classification of a wide variety of organisms based on their similarities and differences.

4. Balance the following redox reaction in acidic solution: I⁻ (aq) + Cr₂O₇²⁻ (aq) -> I₂ (aq) + Cr³⁺ (aq). Identify the oxidizing agent and reducing agent.

Correct answer: A

Rationale: . I⁻ loses an electron (oxidation), Cr₂O₇²⁻ gains electrons (reduction).

5. What is the name for the smallest amount of an element that can exist independently and retain its chemical properties?

Correct answer: A

Rationale: An atom is the fundamental building block of an element, consisting of a nucleus and electrons.

6. A patient's temperature is 98.6 degrees Fahrenheit. What is their temperature in degrees Celsius (1°F = 5/9°C)?

Correct answer: A

Rationale: Subtract 32 from the Fahrenheit temperature (98.6°F) and then multiply by 5/9 to get 37°C.
