1. What is the scientific name for the common housefly?

• A. Musca domestica
• B. Drosophila melanogaster
• C. Apis mellifera
• D. Anopheles gambiae

Correct answer: A

Rationale: Musca domestica is the scientific name for the common housefly. This species is known for being a common pest found in and around human habitations. Drosophila melanogaster (option B) is a species of fruit fly commonly used in genetic research. Apis mellifera (option C) is the scientific name for the western honeybee. Anopheles gambiae (option D) is a species of mosquito known for being a vector of malaria.

2. Select the noun that the underlined adjectives describe: 'Two weeks after his surgery, Henry felt strong and healthy.'

• A. weeks
• B. his
• C. surgery
• D. Henry

Correct answer: D

Rationale: The correct answer is D (Henry) because the adjectives 'strong and healthy' describe 'Henry.' In this sentence, 'Henry' is the subject being described as strong and healthy, not 'weeks,' 'his,' or 'surgery.' While 'weeks' and 'surgery' are nouns mentioned in the sentence, they are not the nouns being described by the adjectives in question. 'His' is a possessive pronoun referring to Henry and does not match the criteria of being directly described by the adjectives 'strong and healthy.' Therefore, 'Henry' is the noun that the adjectives specifically describe in this context.

3. Which of the following best describes a chemical change?

• A. Melting ice to form water
• B. Dissolving sugar in water
• C. Burning wood to produce ash
• D. Crushing a can to reduce its size

Correct answer: C

Rationale: A chemical change involves a chemical reaction where new substances are formed. Burning wood to produce ash is an example of a chemical change because the wood undergoes a chemical reaction to form a new substance (ash). In this process, the chemical composition of wood changes to produce ash, which is a new substance. On the other hand, melting ice to form water, dissolving sugar in water, and crushing a can to reduce its size are examples of physical changes. In these instances, the substances may change their physical state or appearance but do not undergo a chemical reaction to form new substances. Therefore, choice C is the correct answer as it represents a chemical change, while choices A, B, and D represent physical changes.

4. Fill in the blank with the correct subordinating conjunction: '... the class was difficult, Allison passed with flying colors.'

• A. If
• B. Since
• C. Because
• D. Although

Correct answer: D

Rationale: The correct conjunction is 'Although.' In this sentence, there is a contrast being made between the difficulty of the class and Allison's success, indicating that despite the class being difficult, she excelled. 'If' implies a condition, 'Since' indicates a reason, and 'Because' shows causation, which do not fit the context of the sentence where a contrast is being expressed.

5. What is the main purpose of biological classification?

• A. To create a rigid and unchanging system for labeling organisms
• B. To understand the diversity and interconnectedness of life
• C. To simplify nature into neat and tidy categories
• D. To assign organisms to specific ecological niches

Correct answer: B

Rationale: Biological classification, also known as taxonomy, is the science of categorizing and organizing living organisms based on shared characteristics. The main purpose of biological classification is not to create a rigid and unchanging system (option A) or to simplify nature into neat and tidy categories (option C). Instead, it aims to help us understand the diversity of life on Earth and how different organisms are related to each other. By classifying organisms into groups based on their evolutionary relationships, we can gain insights into the interconnectedness of life and better appreciate the complexity and beauty of the natural world. Assigning organisms to specific ecological niches (option D) is more related to ecological studies rather than biological classification.
