1. What is the term for the transfer of energy through a food chain?
- A. Photosynthesis
- B. Cellular respiration
- C. Transpiration
- D. Trophic cascade
Correct answer: D
Rationale: Rationale: A) Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll. B) Cellular respiration is the process by which cells break down glucose and other molecules to produce energy in the form of ATP. C) Transpiration is the process by which water is absorbed by plant roots, moves through the plant, and is released as vapor through pores in the leaves. D) Trophic cascade refers to the transfer of energy through a food chain or food web, where the impact of a predator on its prey cascades down the food chain, affecting multiple trophic levels. This term describes the indirect effects that predators can have on lower trophic levels, influencing the entire ecosystem.
2. How is work defined in terms of force and displacement?
- A. Work is the product of force and displacement in any direction
- B. Work is done only when the displacement is vertical
- C. Work is done only when the force and displacement are perpendicular
- D. Work is the product of force and displacement in the direction of the force
Correct answer: d
Rationale: Work is calculated as the force applied to an object multiplied by the displacement of the object in the direction of the force.
3. Define power in physics.
- A. The rate of change of energy
- B. The rate of doing work or transferring energy
- C. The measure of an object's potential energy
- D. The force exerted on an object
Correct answer: b
Rationale: Power is the rate at which work is done or energy is transferred or converted.
4. Which biome is characterized by cold temperatures, permafrost, and coniferous trees?
- A. Tundra
- B. Desert
- C. Rainforest
- D. Savanna
Correct answer: A
Rationale: 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. 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. 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
5. Which preposition best completes the sentence: "She borrowed money _____ her friend."
- A. of
- B. from
- C. on
- D. for
Correct answer: B
Rationale: "From" indicates the source of the borrowed money.
