1. DNA bases include all but which of the following?

• A. Adenine
• B. Thymine
• C. Uracil
• D. Cytosine

Correct answer: C

Rationale: The correct answer is C: Uracil. Uracil is not a DNA base; it is a base found only in RNA. The four bases in DNA are Adenine, Thymine, Cytosine, and Guanine. Choice A, Adenine, is a correct DNA base. Choice B, Thymine, is a correct DNA base. Choice D, Cytosine, is a correct DNA base. Therefore, Uracil is the only incorrect choice among the options provided.

2. How are elements arranged in the periodic table?

• A. By their atomic mass
• B. By their chemical properties
• C. By their physical state
• D. By their charge

Correct answer: B

Rationale: Elements are arranged in the periodic table based on their chemical properties, making choice B the correct answer. The periodic table is organized so that elements with similar chemical properties are grouped together in columns, known as groups or families. This arrangement allows for the identification of trends in the behavior of elements and predicting their properties based on their position in the table. Choices A, C, and D are incorrect because the periodic table primarily focuses on the chemical properties of elements, not solely on atomic mass, physical state, or charge.

3. Which adjective best completes the sentence?

• A. More greater
• B. Great
• C. Best
• D. More greatest

Correct answer: C

Rationale: 'Best' is the correct choice because it conveys the highest quality or degree in comparison, which is appropriate in this context. The sentence is discussing the opinion of coffee experts about a particular coffee blend, indicating that it is the most superior among the options. Choices A, B, and D are grammatically incorrect or redundant. 'More greater' is incorrect due to the redundant use of 'more' and 'greater.' 'Great' is a comparative form that does not fit the superlative context required. 'More greatest' is incorrect due to the unnecessary use of 'more' alongside 'greatest,' which is already a superlative form.

4. A symptom that is exacerbated is ____?

• A. Improving
• B. Made worse
• C. Stayed the same
• D. Ameliorated

Correct answer: B

Rationale: The correct answer is 'B) Made worse.' Exacerbated means to make a condition more severe or intense. Therefore, if a symptom is exacerbated, it is getting worse, not improving (choice A), staying the same (choice C), or ameliorated (choice D), which means to improve or make better.

5. To which system do the ovaries belong?

• A. skeletal system
• B. nervous system
• C. lymphatic system
• D. reproductive system

Correct answer: D

Rationale: The correct answer is D: reproductive system. The ovaries are essential organs of the female reproductive system. They play a vital role in producing eggs and secreting hormones like estrogen and progesterone. The skeletal system (choice A) consists of bones and tissues that support the body, the nervous system (choice B) controls body functions and responses, and the lymphatic system (choice C) helps the body fight off infections. Therefore, the ovaries belong to the reproductive system.
