1. Which biome is characterized by cold temperatures, permafrost, and coniferous trees?

• A. Tundra
• B. Desert
• C. Rainforest
• D. Savanna

Correct answer: A

Rationale: A) Tundra: This biome is characterized by cold temperatures, permafrost (permanently frozen subsoil), and vegetation such as mosses, lichens, and coniferous trees like spruce and fir. The tundra is found in high latitudes near the Arctic Circle and high altitudes in mountainous regions. It is a cold and harsh environment where the ground remains frozen for a significant part of the year. The coniferous trees in this biome are adapted to survive in extreme cold conditions. B) Desert: Deserts are characterized by low precipitation levels and high temperatures, with sparse vegetation adapted to arid conditions. C) Rainforest: Rainforests are characterized by high levels of rainfall, warm temperatures, and dense vegetation with a variety of plant and animal species. D) Savanna: Savannas are tropical grasslands with scattered trees and shrubs, characterized by a distinct wet and dry season. They have a different climate pattern compared to the cold temperatures and permafrost found in the tundra biome. In this case, the description of cold temperatures, permafrost, and coniferous trees aligns most closely with the characteristics of the tundra biome, making option A the correct answer.

2. Which of the following describes the structure of the above passage?

• A. problem-solution
• B. sequence
• C. comparison-contrast
• D. cause-effect

Correct answer: C

Rationale: The correct answer is C: 'comparison-contrast.' Throughout the passage, the author compares and contrasts the Arthurian writings of Malory and Tennyson, highlighting the differences and similarities between their approaches to the Arthurian legends. The structure of the passage is focused on contrasting Malory's prose style and moral elements with Tennyson's poetic and romantic approach, making it a clear comparison-contrast. Choices A, B, and D are incorrect. The passage does not present a problem and its solution, follow a strict sequence of events, or outline cause-effect relationships; instead, it emphasizes the differences and similarities between the two authors' interpretations of the Arthurian stories.

3. What mnemonic helps in recalling metric conversions?

• A. King Hector Died By Drinking Chocolate Milk
• B. Kittens Have Delighted By Dancing Cool Moves
• C. Memorize Your Units Well
• D. Convert These Every Time

Correct answer: A

Rationale: The mnemonic 'King Hector Died By Drinking Chocolate Milk' aids in recalling metric prefixes in order: kilo-, hecto-, deca-, base (meter, liter, gram), deci-, centi-, milli-. Choice B does not provide a relevant mnemonic for metric conversions. Choices C and D do not offer a helpful phrase for remembering metric prefixes, making them incorrect.

4. DNA has both a 'sense' and 'antisense' strand. What is true about the antisense strand?

• A. It runs 5' to 3'.
• B. It runs 3' to 5'.
• C. It is used in replication.
• D. It is the direction DNA is stored.

Correct answer: B

Rationale: The correct answer is B: 'It runs 3' to 5'. The antisense strand runs in the 3' to 5' direction, complementing the sense strand. Choice A is incorrect as the antisense strand runs in the opposite direction, which is 3' to 5'. Choice C is incorrect because the antisense strand is not directly involved in replication. Choice D is incorrect as the direction DNA is stored is not determined by the antisense strand.

5. Which of the following is NOT a function of the skeletal system?

• A. Support and structure
• B. Production of red blood cells
• C. Storage of minerals like calcium
• D. Insulation of the body

Correct answer: D

Rationale: The skeletal system's primary functions include support and structure, protection of internal organs, movement facilitation, production of blood cells, and storage of minerals like calcium. Insulation of the body is not a function of the skeletal system. Insulation, typically involving fat under the skin, helps regulate body temperature but is not a direct function of the skeletal system. Choice B, the production of red blood cells, is a function of the skeletal system as it occurs in the bone marrow within the bones. Choices A and C are also correct functions of the skeletal system.
