1. Enzymes can _ reactions.

• A. Catalyze
• B. Inhibit
• C. Stop
• D. None of the above

Correct answer: A

Rationale: Enzymes function as catalysts that promote and accelerate chemical reactions in biological systems. They do this by lowering the activation energy required for the reactions to occur, thereby speeding up the process without being consumed in the reaction. Enzymes facilitate reactions rather than inhibiting or stopping them. Therefore, the correct answer is 'Catalyze.' 'Inhibit' and 'Stop' are incorrect because enzymes do not hinder or halt reactions but rather enhance them.

2. What punctuation is needed in this sentence to make it correct? Take this fast-acting cough medicine after your next meal.

• A. Period
• B. Comma
• C. Colon
• D. Hyphen

Correct answer: A

Rationale: The correct answer is A: 'Period'. The sentence 'Take this fast-acting cough medicine after your next meal.' is a complete sentence and requires a period at the end to indicate a full stop. A comma (Choice B) is not suitable here as it would create a comma splice. A colon (Choice C) is not needed as there is no introductory clause or list following it. A hyphen (Choice D) is used to join compound words or for other specific purposes, not to end a sentence.

3. What is the definition of the word ENVIRONMENT?

• A. the major ideas of the quality of life
• B. the assistance found outside the family
• C. the elements inside and outside of a person
• D. the positive and negative aspects of a home

Correct answer: C

Rationale: The word 'environment' refers to the surroundings or conditions in which a person, animal, or plant lives or operates. It encompasses the elements both inside and outside of an individual, including physical, biological, social, and cultural factors. Option C, which mentions the elements inside and outside of a person, is the most accurate description of the word 'environment.' Choices A, B, and D do not capture the comprehensive nature of the term 'environment' and are therefore incorrect.

4. Which feature of the ear is most medial?

• A. Pinna
• B. Tympanic membrane
• C. Cochlea
• D. Outer canal

Correct answer: B

Rationale: The tympanic membrane, also known as the eardrum, is the most medial feature in the ear. It separates the outer ear from the middle ear and serves as a barrier that vibrates in response to sound waves, transmitting vibrations to the middle ear ossicles. The pinna, cochlea, and outer canal are located more laterally in the ear anatomy. The pinna is the visible part of the ear located on the lateral side of the head, the cochlea is a spiral-shaped structure in the inner ear responsible for hearing, and the outer canal refers to the external auditory canal leading to the eardrum.

5. In a survey, 120 people were asked if they could swim. If 85% said they could, how many people could swim?

• A. 100
• B. 102
• C. 110
• D. 90

Correct answer: B

Rationale: To find the number of people who could swim, multiply the total number surveyed by the percentage who said they could swim. In this case, 85% of 120 people is calculated as 0.85 * 120, resulting in 102 people who could swim. Choice A (100) is incorrect because this does not account for the percentage that said they could swim. Choice C (110) is incorrect as it is above the total number surveyed. Choice D (90) is incorrect as it does not consider the percentage who said they could swim.
