What is Diffusion?
- A. Movement of materials from low concentration to high concentration
- B. Movement of materials from high concentration to low concentration
- C. Absorption of nutrients
- D. Breaking of materials
Correct Answer: B
Rationale: Diffusion is the process where substances move from an area of high concentration to an area of low concentration. This movement occurs due to the random motion of particles and continues until equilibrium is reached. Choice A is incorrect because diffusion occurs down the concentration gradient, from high to low concentration, not from low to high concentration. Choice C is incorrect as it refers to the uptake of substances by cells, not the general process of diffusion. Choice D is incorrect as it does not accurately describe the process of diffusion; diffusion involves the movement of substances, not the breaking of materials.

What is the best description for the term Aseptic?
- A. Sterilized
- B. Purified
- C. Contaminated
- D. Polluted
Correct Answer: B
Rationale: The correct answer is B: 'Purified.' Aseptic means free from contamination or sterile. While 'Sterilized' (choice A) is related to the elimination of all microorganisms, aseptic goes beyond sterilization to ensure freedom from contamination in a broader sense. 'Contaminated' (choice C) and 'Polluted' (choice D) are incorrect as they mean the opposite of aseptic, implying the presence of unwanted or harmful substances.
LABILE also means .
- A. Extremely changing
- B. Suicidal
- C. Rapidly changing
- D. With a high fever
Correct Answer: A
Rationale: The word 'labile' is used to describe something that is constantly changing or easily altered. Therefore, the best synonym for 'labile' is 'extremely changing.' Choice B, 'suicidal,' is incorrect as it does not relate to the meaning of 'labile.' Choice C, 'rapidly changing,' is close but not as precise as 'extremely changing.' Choice D, 'with a high fever,' is completely unrelated to the meaning of 'labile.'
Which phrase should be moved to the end of the sentence? 'The painter decided to use the urn as his subject with flowers on the table.'
- A. as his subject
- B. with flowers on the table
- C. use the urn as his subject
- D. with the urn
Correct Answer: B
Rationale: Moving 'with flowers on the table' to the end of the sentence improves the sentence flow and clarity. This placement helps to maintain a logical sequence of events, enhancing the reader's understanding. Choice A, 'as his subject,' is an integral part of the main action and should not be moved. Choice C, 'use the urn as his subject,' disrupts the verb-object relationship and makes the sentence less coherent. Choice D, 'with the urn,' lacks context and does not provide a smooth transition when placed at the end of the sentence.
What does Debilitating mean?
- A. Incapacitating
- B. Weakening
- C. Empowering
- D. Strengthening
Correct Answer: A
Rationale: The correct answer is A: 'Incapacitating.' Debilitating means causing incapacity or weakness, making choice A the most appropriate. Choices B, C, and D are incorrect because they represent the opposite of what debilitating means. Weakening (choice B), Empowering (choice C), and Strengthening (choice D) all convey a sense of increasing strength or ability, which is the opposite of the meaning of debilitating.
When a body part has atrophied, it has ____?
- A. Enlarged
- B. Withered
- C. Swollen

Correct Answer: B
Rationale: The correct answer is B: 'Withered.' When a body part atrophies, it shrinks or wastes away.
