1. Your hypothesis predicts that exposing plants to classical music will enhance their growth. How could you design an experiment to test this hypothesis?

• A. Play classical music to all plants in the greenhouse and compare their growth to a control group without music.
• B. Select plants with personal preferences for classical music and compare their growth to plants who dislike it.
• C. Play different genres of music to separate plants and analyze which genre promotes the most growth.
• D. Observe the behavior of plants listening to music and measure their happiness levels.

Correct answer: A

Rationale: To test the hypothesis that exposing plants to classical music enhances their growth, the most appropriate experimental design would be to play classical music to all plants in the greenhouse (experimental group) and compare their growth to a control group of plants that are not exposed to any music. This design allows for a direct comparison between the effects of classical music exposure on plant growth, eliminating confounding variables that may arise from individual plant preferences or different music genres.

2. What is the common name for the compound CH₃COOH?

• A. Acetic acid
• B. Formic acid
• C. Butyric acid
• D. Propionic acid

Correct answer: A

Rationale: CH₃COOH is commonly known as acetic acid. The other choices represent different organic acids.

3. He wants to influence the customary way of thinking and behaving that is shared by the

• A. Organizational chart
• B. Cultural network
• C. Organizational structure
• D. Organizational culture

Correct answer: A

Rationale: The correct answer is A: "Organizational chart." In the context of the question, the individual is aiming to impact the established patterns of thinking and behavior within a group or organization. An organizational chart typically depicts the formal structure of an organization, including roles, relationships, and reporting lines. By influencing the organizational chart, the individual can potentially shape the hierarchical structure and decision-making processes, thereby impacting the customary way of thinking and behaving within the organization. Options B, C, and D do not directly refer to the visual representation of roles and relationships within an organization, making them incorrect choices for this question.

4. What is the building block of DNA?

• A. Amino acid
• B. Nucleotide
• C. Nucleotide
• D. Fatty acid

Correct answer: B

Rationale: Rationale: - Amino acids are the building blocks of proteins, not DNA. - Nucleotide is the correct building block of DNA. A nucleotide consists of a sugar (deoxyribose in DNA), a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine). - The option "C) Nucleotide" is a duplicate of the correct answer "B) Nucleotide." - Fatty acids are not the building blocks of DNA; they are a type of lipid molecule.

5. Which of the following is an example of an aromatic compound?

• A. Ethanol
• B. Toluene
• C. Acetone
• D. Butanal

Correct answer: B

Rationale: Toluene is an aromatic compound. The other choices are not aromatic compounds.

6. A patient needs to take 2 tablets for every 30 pounds of body weight. If they weigh 150 pounds, how many tablets should they take?

• A. 5
• B. 10
• C. 15
• D. 20

Correct answer: A

Rationale: Divide the patient's weight (150 pounds) by the ratio denominator (30 pounds/tablet) to get 5 tablets.
