1. What characteristic unites all organisms in the kingdom Animalia?

• A. Multicellularity and heterotrophy
• B. Unicellular nature
• C. Photosynthesis
• D. Cell walls made of chitin

Correct answer: A

Rationale: A) Multicellularity and heterotrophy: This is the correct answer because all organisms in the kingdom Animalia are multicellular (composed of multiple cells) and exhibit heterotrophy (obtain nutrients by consuming other organisms). B) Unicellular nature: This is incorrect because organisms in the kingdom Animalia are multicellular, not unicellular. C) Photosynthesis: This is incorrect because organisms in the kingdom Animalia do not perform photosynthesis; they are heterotrophs that obtain nutrients by consuming other organisms. D) Cell walls made of chitin: This is incorrect because organisms in the kingdom Animalia do not have cell walls made of chitin. Chitin is a structural polysaccharide found in the cell walls of fungi, not animals.

2. Based on the word choices in the following sentence, which of the following is the most likely meaning of the prefix per-?

• A. Across
• B. By
• C. With
• D. Through

Correct answer: D

Rationale: The prefix 'per-' commonly means 'through,' indicating movement from one side to the other or completely through something. In this context, 'through' is the most fitting interpretation as it aligns with the idea of complete passage or thorough involvement. The other options do not convey the concept of going completely through something. 'Across' implies moving from one side to another but not necessarily all the way through. 'By' denotes proximity or secondary involvement rather than passage through. 'With' indicates accompaniment or association, which is not reflective of the prefix per- in terms of movement or completion.

3. Which property of a wave determines its energy?

• A. Wavelength
• B. Amplitude
• C. Frequency
• D. Velocity

Correct answer: B

Rationale: The energy of a wave is determined by its amplitude, which is the measure of its maximum displacement from the equilibrium position. Waves with higher amplitudes carry more energy as energy is directly proportional to amplitude. Therefore, the correct answer is B) Amplitude. Choice A (Wavelength) does not determine the energy of a wave; it is related to the spatial length between wave crests. Choice C (Frequency) is not the property that determines a wave's energy; it refers to the number of complete oscillations a wave undergoes in a given time. Choice D (Velocity) is the speed at which a wave propagates through a medium and is not directly related to its energy.

4. Which structure in the lungs is the site of gas exchange?

• A. Trachea
• B. Alveoli
• C. Bronchioles
• D. Diaphragm

Correct answer: B

Rationale: The correct answer is B: Alveoli. Alveoli are tiny air sacs in the lungs where gas exchange occurs. Oxygen from inhaled air diffuses into the bloodstream, while carbon dioxide from the blood is released into the alveoli to be exhaled. The trachea (Choice A) is the windpipe that carries air to and from the lungs, but it is not involved in gas exchange. Bronchioles (Choice C) are small air passages within the lungs that branch off from the bronchi, leading air to the alveoli but not directly involved in gas exchange. The diaphragm (Choice D) is a muscle below the lungs that helps in breathing by expanding and contracting the chest cavity, but it is not the site of gas exchange.

5. Based on the context of the passage, the reader can infer that this information is likely to appear in which of the following types of works?

• A. a scholarly paper
• B. a mystery
• C. a fictional story
• D. a biography

Correct answer: D

Rationale: The information provided in the passage about the skeleton's structure and divisions, along with specific details like the number of bones and their functions, is characteristic of content found in a biography or a reference work focusing on anatomy. Biographies often include detailed factual information about historical figures, their lives, and aspects related to them, such as physical characteristics. A scholarly paper would delve deeper into analysis and research, rather than presenting basic factual information. The content in the passage is purely informative and factual, ruling out the possibility of it being part of a mystery or fictional story, which require narrative and plot elements rather than straightforward facts.
