1. 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.

2. Examine the following decomposition reaction: ABC → ______. Which of the following is a possible set of products for this reaction?

• A. 2AB + C
• B. AB + CD
• C. A + BC
• D. B + C

Correct answer: C

Rationale: In a decomposition reaction, a single reactant breaks down into two or more products. For the decomposition of ABC, a plausible set of products is A + BC. This reaction represents the breakdown of ABC into two separate components: A and BC. The correct choice C aligns with the fundamental concept of decomposition reactions, where a compound disintegrates into simpler substances. Choices A, B, and D do not reflect a proper decomposition reaction as they do not demonstrate the breakdown of the original compound into distinct components.

3. Which property of a wave is responsible for determining its energy?

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

Correct answer: C

Rationale: The correct answer is C, Frequency. The energy of a wave is determined by its frequency, not its amplitude, wavelength, or velocity. According to the equation E = h*f, where E is energy, h is Planck's constant, and f is frequency, the energy of a wave is directly proportional to its frequency. Higher frequency waves carry more energy, while lower frequency waves carry less energy. Therefore, frequency plays a crucial role in determining the energy content of a wave, making it the correct choice in this context.

4. Based on an examination of word parts, which of the following words means 'above the kidney'?

• A. Interrenal
• B. Subrenal
• C. Intrarenal
• D. Suprarenal

Correct answer: D

Rationale: The correct answer is 'Suprarenal.' Breaking down the word parts, 'supra-' means above, and '-renal' pertains to the kidney. Therefore, 'Suprarenal' means above the kidney. Choice A, 'Interrenal,' is incorrect as 'inter-' means between or among. Choice B, 'Subrenal,' is incorrect as 'sub-' means below. Choice C, 'Intrarenal,' is incorrect as 'intra-' means within or inside.

5. In a volleyball game, who can score a point?

• A. the receiving team
• B. the serving team
• C. any team
• D. neither team

Correct answer: B

Rationale: According to the passage, only the serving team can score in a volleyball game. After the ball is served, the serving team earns points by winning a rally. The receiving team aims to stop the serving team and win the rally to gain the serve. Therefore, the correct answer is the serving team. Choices A, C, and D are incorrect as the receiving team does not score points, both teams do not score, and there is indeed scoring in volleyball.
