1. What is the term for the time it takes for a wave to complete one full cycle?

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

Correct answer: C

Rationale: The period of a wave is the time it takes for one complete cycle to occur. It is the duration between two successive points in the wave that are in the same phase. Frequency, on the other hand, refers to the number of cycles of a wave that occur in a given time period. Amplitude represents the maximum displacement of a wave from its equilibrium position. Wavelength is the distance between two consecutive points on a wave that are in phase. Therefore, the correct answer is 'Period' as it specifically refers to the time taken for a wave to complete one full cycle, distinguishing it from the other choices which represent different properties of a wave.

2. If an atom has 32 neutrons, 17 protons, and 19 electrons, what is its charge?

• A. Positive
• B. Negative
• C. Neutral
• D. Cannot be determined

Correct answer: A

Rationale: An atom's charge is determined by the difference between the number of protons and electrons. Since the atom has 17 protons and 19 electrons, the net charge is positive. The excess of two electrons compared to protons results in a positive charge. Choice B (Negative) is incorrect because the atom has more protons than electrons, leading to a positive charge. Choice C (Neutral) is incorrect because the atom has an imbalance between protons and electrons, resulting in a charge. Choice D (Cannot be determined) is incorrect as the charge can be determined based on the given information.

3. What was the author's intent in the passage?

• A. To persuade
• B. To entertain
• C. To express feeling
• D. To inform

Correct answer: D

Rationale: The author's primary intent in the passage is to inform the reader about historical events related to the succession of monarchs in England and Scotland. The passage presents factual information about the reigns of King James I, King Charles I, King Charles II, King James II, and the attempted recapture of the throne by Bonnie Prince Charlie. It details how religious differences and political conflicts shaped the history of England and Scotland. The other choices are incorrect because the author's focus is on providing historical facts rather than persuading, entertaining, or expressing personal feelings.

4. Which of the following is NOT a characteristic of mitosis?

• A. The replication of DNA
• B. The condensation of chromosomes
• C. The separation of sister chromatids
• D. The formation of haploid cells

Correct answer: D

Rationale: Rationale: A) The replication of DNA is a characteristic of mitosis. Before cell division occurs, the DNA is replicated to ensure that each daughter cell receives a complete set of genetic information. B) The condensation of chromosomes is a characteristic of mitosis. During mitosis, the chromosomes condense and become visible under a microscope as distinct structures. C) The separation of sister chromatids is a crucial step in mitosis. During anaphase, the sister chromatids are pulled apart and move to opposite poles of the cell to ensure that each daughter cell receives a complete set of chromosomes. D) The formation of haploid cells is NOT a characteristic of mitosis. Mitosis results in the formation of two identical diploid daughter cells, each containing the same number of chromosomes as the parent cell. Haploid cells are typically formed through the process of meiosis, not mitosis.

5. What is the measure of the total amount of space occupied by an object?

• A. Mass
• B. Density
• C. Weight
• D. Volume

Correct answer: D

Rationale: Volume is the measure of the total amount of space occupied by an object. Mass refers to the amount of matter in an object, density is the mass per unit volume, and weight is the force of gravity acting on an object. When determining the space occupied by an object, volume is the appropriate measurement to consider. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not directly indicate the total amount of space occupied by an object. Mass, density, and weight are relevant in different contexts and measurements compared to volume.
