1. Select the meaning that best fits the following word: injurious.

• A. Toxic
• B. Palatable
• C. Amenable
• D. Harmless

Correct answer: A

Rationale: The correct answer is A, 'Toxic.' 'Injurious' means harmful or likely to cause injury, similar to 'toxic.' Choices B, C, and D are incorrect because 'palatable' means pleasant to taste, 'amenable' means cooperative or willing to agree, and 'harmless' means not causing harm.

2. Select the strand of DNA that would match this segment: ACTTGCA

• A. TGAACGT
• B. GACCATG
• C. ACTTGCA
• D. None of the above

Correct answer: A

Rationale: The correct match for the DNA segment ACTTGCA is TGAACGT. In DNA, adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G). Therefore, the complementary strand to ACTTGCA should be TGAACGT, making choice A the correct answer. Choice B (GACCATG) does not follow the base pairing rules; hence, it is incorrect. Choice C (ACTTGCA) is the original segment, not its complementary strand. Choice D is incorrect as well because a matching strand does exist.

3. The information presented is

• A. Balanced in its view of public speaking.
• B. Favoring people with low-pitched voices.
• C. Slanted against people with piercing voices.
• D. Neutral toward both high- and low-pitched voices.

Correct answer: C

Rationale: The correct answer is C. The paragraph is biased against people with piercing or harsh voices, suggesting they are less desirable as public speakers, newscasters, or political candidates. The text explicitly mentions that harsh voice qualities, like being shrill, grating, hard, piercing, brassy, loud, or nasal, are undesirable and may make people uncomfortable when speaking. It also highlights that tension leading to harsh voice qualities is more common in higher-pitched voices, which are typically associated with women, making them less preferred for public speaking roles. Choices A, B, and D are incorrect because the text does not suggest a balanced view, favor low-pitched voices, or maintain neutrality towards both high- and low-pitched voices; instead, it emphasizes the negative impact of harsh and piercing voices.

4. A tissue examined under the microscope exhibits the following characteristics: cells found on the internal surface of the stomach, no extracellular matrix, cells tall and thin, no blood vessels in the tissue. What type of tissue is this?

• A. Epithelial
• B. Connective tissue
• C. Cartilage
• D. Nervous

Correct answer: A

Rationale: The correct answer is 'Epithelial.' Epithelial tissue is characterized by cells lining surfaces and cavities, such as the stomach. It does not contain blood vessels, and the cells are tall and thin. The absence of an extracellular matrix is typical of epithelial tissue, making it the most suitable choice in this scenario. Connective tissue, like cartilage and nervous tissue, have different characteristics that do not align with the description provided in the question.

5. Which of the following is equivalent to 0.0009?

• A. 0.09%
• B. 9%
• C. 0.01%
• D. 0.90%

Correct answer: A

Rationale: The correct answer is A: 0.09%. To convert 0.0009 to a percentage, move the decimal point four places to the right and add a percentage sign. Therefore, 0.0009 is equal to 0.09%. Choice B (9%) is incorrect as it represents 0.09 without the decimal point adjustment. Choice C (0.01%) is incorrect as it represents 0.0009 with one less zero. Choice D (0.90%) is incorrect as it represents 0.9 not 0.0009.
