1. Ibexes are wild mountain goats that live in the Alps and the mountains of Asia. They climb very steep slopes. They are sure-footed and can easily leap from rock to rock. In winter, they replace their summer coat with thicker hair and a wooly undercoat.

• A. Ibexes are wild mountain goats that are very agile.
• B. Ibexes are found in lowlands and highlands.
• C. Ibexes like to climb steep slopes in the mountains.
• D. Ibexes have adapted to life in the mountains.

Correct answer: D

Rationale: The correct answer is 'Ibexes have adapted to life in the mountains' because it serves as a concluding sentence that summarizes the content of the paragraph. This statement encapsulates the information provided about ibexes living in the Alps and Asian mountains, climbing steep slopes, being sure-footed, and changing their coats in winter. Choice A is incorrect because the text does not specifically mention their agility. Choice B is incorrect as the text only mentions the Alps and Asian mountains, not lowlands. Choice C is also incorrect as the text mentions ibexes climbing steep slopes, not just liking to do so.

2. What is the process by which muscles convert chemical energy (ATP) into mechanical energy (movement)?

• A. Photosynthesis
• B. Cellular respiration
• C. Muscle contraction
• D. The sliding filament theory

Correct answer: C

Rationale: Muscle contraction is the correct answer. It is the process by which muscles convert chemical energy (ATP) into mechanical energy (movement). During muscle contraction, the sliding filament theory explains how actin and myosin filaments slide past each other, causing muscle fibers to shorten and generate force. Photosynthesis (option A) is the process by which plants convert light energy into chemical energy. Cellular respiration (option B) is the process by which cells generate ATP from glucose and oxygen. The sliding filament theory (option D) is a detailed explanation of the molecular events that occur during muscle contraction but is not the overall process of converting energy into movement; it focuses on the mechanism within the process of muscle contraction.

3. How many millimeters are in 0.75 centimeters?

• A. 7.5 mm
• B. 0.75 mm
• C. 75 mm
• D. 75 cm

Correct answer: C

Rationale: To convert centimeters to millimeters, you need to multiply by 10 since there are 10 millimeters in a centimeter. Therefore, 0.75 centimeters equals 0.75 x 10 = 7.5 millimeters, not 75 millimeters (Choice C). Choice A (7.5 mm) is the correct conversion, while Choice B (0.75 mm) and Choice D (75 cm) are incorrect conversions.

4. Select the context clue from the following sentence that helps you define the word pungent: 'The pungent odor in the room made everyone’s eyes tear for a few minutes.'

• A. odor
• B. room
• C. made
• D. tear

Correct answer: A

Rationale: The correct answer is 'A: odor.' In the sentence provided, 'odor' serves as the context clue that helps define 'pungent' as a strong smell. The word 'pungent' commonly refers to something having a sharply strong scent, and 'odor' directly relates to this meaning in the sentence. Choices 'B: room,' 'C: made,' and 'D: tear' do not provide contextual information about the meaning of 'pungent,' making them incorrect choices for defining the word in this context.

5. What is an alteration in the normal gene sequence called?

• A. DNA mutation
• B. Gene migration
• C. Polygenic inheritance
• D. Incomplete dominance

Correct answer: A

Rationale: A DNA mutation is the correct term used to describe an alteration in the normal gene sequence. It refers to changes in the DNA sequence that can result in different traits or characteristics. Gene migration involves the movement of genes between populations, polygenic inheritance refers to the inheritance of traits controlled by multiple genes, and incomplete dominance is a pattern of inheritance where neither allele is dominant.
