1. What principle explains the relationship between pressure, volume, and temperature for ideal gases?

• A. Law of conservation of energy
• B. Newton's laws of motion
• C. Ideal gas law
• D. Archimedes' principle

Correct answer: C

Rationale: The ideal gas law (PV = nRT) relates pressure, volume, and temperature for ideal gases at constant number of moles and temperature.

2. The largest level of ecological organization is a:

• A. Population
• B. Community
• C. Ecosystem
• D. Biome

Correct answer: D

Rationale: Rationale: A) Population: A population consists of individuals of the same species living in the same area. It is a smaller level of ecological organization compared to a biome. B) Community: A community consists of populations of different species living and interacting in the same area. It is a larger level of organization than a population but smaller than an ecosystem or biome. C) Ecosystem: An ecosystem includes all living organisms (biotic factors) and their physical environment (abiotic factors) interacting in a particular area. It is a larger level of organization than a community but smaller than a biome. D) Biome: A biome is the largest level of ecological organization and encompasses a large geographic area characterized by a specific climate, vegetation, and animal life. Biomes can be found on multiple continents and are defined by similar abiotic and biotic factors.

3. What part of speech is the underlined word in the sentence "I was disappointed by the outcome"?

• A. Verb
• B. Noun
• C. Adjective
• D. Adverb

Correct answer: C

Rationale: "Disappointed" modifies the pronoun "I," making it an adjective.

4. How does friction affect motion?

• A. Friction increases speed
• B. Friction decreases speed
• C. Friction has no impact on speed
• D. Friction causes objects to float

Correct answer: b

Rationale: Friction opposes motion, leading to a decrease in speed or hindering movement.

5. Which of the following is the neutral subatomic particle found in the nucleus of an atom?

• A. Electron
• B. Proton
• C. Neutron
• D. Positron

Correct answer: C

Rationale: Neutrons are subatomic particles found in the nucleus of an atom that have no charge. They have a mass of approximately 1 atomic mass unit (amu). The number of neutrons in an atom's nucleus contributes to the mass number of the atom, which is the total number of protons and neutrons in the nucleus.

6. Which organelle is responsible for controlling the activities of the cell?

• A. Golgi apparatus
• B. Mitochondria
• C. Nucleus
• D. Ribosomes

Correct answer: C

Rationale: Rationale: The nucleus is the organelle responsible for controlling the activities of the cell. It contains the cell's genetic material (DNA) and serves as the command center of the cell, regulating gene expression and directing cellular activities. The nucleus plays a crucial role in cell growth, metabolism, and reproduction. The Golgi apparatus is involved in processing and packaging proteins, the mitochondria are responsible for producing energy in the form of ATP, and ribosomes are involved in protein synthesis. However, none of these organelles have the primary function of controlling the activities of the cell like the nucleus does.
