1. What is the process by which muscle tissue wastes away due to disuse or lack of nutrients?

• A. Hypertrophy
• B. Atrophy
• C. Fibrosis
• D. Rigor mortis

Correct answer: B

Rationale: Atrophy is the correct term for the process by which muscle tissue wastes away due to disuse or lack of nutrients. It is essential to differentiate atrophy from hypertrophy, which is the increase in muscle size due to exercise or strength training. Fibrosis involves the formation of excess fibrous connective tissue, which is distinct from muscle wasting. Rigor mortis, on the other hand, is the stiffening of muscles that occurs after death and is not related to muscle wasting during life.

2. Which technique best helps maintain consistency in writing style?

• A. Writing freely without a clear outline or structure.
• B. Using different vocabulary and sentence structures in each paragraph.
• C. Establishing a style guide with agreed-upon terminology and formatting.
• D. Relying on thesaurus suggestions for varied word choices.

Correct answer: C

Rationale: Establishing a style guide with agreed-upon terminology and formatting is the most effective technique to maintain consistency in writing style. A style guide ensures that writers adhere to specific guidelines regarding tone, terminology, and formatting, thereby creating a cohesive and uniform writing style across different pieces of writing. This consistency helps enhance readability and reinforces the brand or voice associated with the written content. Choices A, B, and D are incorrect because they do not promote consistency in writing style. Writing freely without structure can lead to inconsistency, using different vocabulary and sentence structures can create disjointed writing, and relying solely on thesaurus suggestions may result in awkward or inappropriate word choices that do not contribute to maintaining a consistent writing style.

3. The transfer of energy through feeding relationships in an ecosystem is called a:

• A. Food Chain
• B. Food Web
• C. Habitat
• D. Biome

Correct answer: A

Rationale: A food chain is a linear sequence of organisms where each organism consumes the one below it and is consumed by the one above it. This transfer of energy through feeding relationships is a fundamental concept in ecology to understand how energy flows through an ecosystem. In a food chain, energy is transferred from producers (plants) to primary consumers (herbivores), then to secondary consumers (carnivores), and so on. Each step in the food chain represents a trophic level, and energy is lost as heat at each level, resulting in a pyramid-shaped energy flow. Food webs, on the other hand, represent a more complex network of interconnected food chains within an ecosystem. Habitats refer to the specific environments where organisms live, and biomes are large geographical areas characterized by specific climates and vegetation types. Therefore, the correct answer is 'Food Chain' as it specifically describes the linear transfer of energy through feeding relationships in an ecosystem.

4. Hampton was born and raised in Maywood, a suburb of Chicago, Illinois, in 1948. Which revision best improves the sentence?

• A. NO CHANGE
• B. in Maywood, of Chicago, Illinois in 1948.
• C. in Maywood, of Chicago, Illinois, in 1948.
• D. in Chicago, Illinois of Maywood in 1948.

Correct answer: C

Rationale: The corrected choice C 'in Maywood, of Chicago, Illinois, in 1948.' is the best revision as it places commas around the city and state, as well as around the year, improving clarity and readability. Choice A is incorrect as it does not provide the necessary punctuation for clarity. Choice B incorrectly places 'of Chicago' between 'Maywood' and 'Illinois,' disrupting the flow of information. Choice D reverses the order of 'Chicago, Illinois' and 'Maywood,' making it structurally incorrect.

5. Which of the following describes a responsibility of the integumentary system?

• A. Distributing vital substances, such as nutrients, throughout the body.
• B. Blocking pathogens that cause disease.
• C. Sending leaked fluids from the cardiovascular system back to the blood vessels.
• D. Storing bodily hormones that influence gender traits.

Correct answer: B

Rationale: The correct responsibility of the integumentary system is to act as a barrier that blocks pathogens from entering the body, thus helping to prevent diseases and infections. This function serves as the first line of defense for the body against external threats. Choices A, C, and D are incorrect. Choice A is a function of the circulatory system, not the integumentary system. Choice C relates to the lymphatic system, not the integumentary system. Choice D involves the endocrine system, not the integumentary system.
