1. Choose the meaning of the word 'distended' in the following sentence: 'The patient's distended veins were a cause for worry.'

• A. Bleeding
• B. Enlarged
• C. Pressure
• D. Minuscule

Correct answer: B

Rationale: The term 'distended' means swollen or enlarged. In this context, when the patient's veins are described as distended, it implies that they are expanded or swollen beyond their normal size, which can be a cause for worry due to potential health implications. Choice A ('Bleeding') is incorrect as 'distended' does not refer to bleeding but rather to being swollen. Choice C ('Pressure') is incorrect as 'distended' does not directly imply pressure but rather enlargement. Choice D ('Minuscule') is incorrect as 'distended' means the opposite of minuscule, indicating something enlarged or swollen.

2. Select the word or phrase that makes this sentence grammatically correct: 'A child is not yet old enough to know what is healthy for ____.'

• A. him or her
• B. them
• C. it
• D. she or he

Correct answer: A

Rationale: The correct answer is 'him or her' because it agrees with the singular noun 'child.' When referring to a singular subject of unknown gender, 'him or her' is a suitable pronoun choice to maintain grammatical correctness. Options B, C, and D are incorrect as they do not match the singular form of 'child.' Using 'them' (B) would be plural, 'it' (C) is not appropriate for a person, and 'she or he' (D) is unnecessarily wordy and less commonly used in modern English.

3. What process involves the movement of water molecules through a selectively permeable membrane?

• A. Diffusion
• B. Osmosis
• C. Active Transport
• D. Facilitated Diffusion

Correct answer: B

Rationale: Osmosis is the process specifically involving the movement of water molecules through a selectively permeable membrane, from an area of higher water concentration to an area of lower water concentration. This process helps balance concentrations on both sides of the membrane. Choice A, Diffusion, refers to the movement of particles from an area of higher concentration to an area of lower concentration, not specific to water. Choice C, Active Transport, requires energy to move substances against their concentration gradient, unlike osmosis. Choice D, Facilitated Diffusion, involves the use of transport proteins to move specific substances across membranes, not limited to water molecules.

4. Cytosine and thymine are known as:

• A. Purines
• B. Pyrimidines
• C. Both
• D. None of the above

Correct answer: B

Rationale: Cytosine and thymine are known as pyrimidines because they have a single carbon ring structure. Purines, on the other hand, have a double-ring structure. Choice A ('Purines') is incorrect because purines have a double-ring structure, unlike cytosine and thymine. Choice C ('Both') is incorrect as it implies they are both purines and pyrimidines, which is not true. Choice D ('None of the above') is incorrect because cytosine and thymine are indeed pyrimidines.

5. Which word in the following sentence is a conjunction: 'The little girl wanted a cookie, but she didn’t take one.'

• A. little
• B. but
• C. take
• D. the

Correct answer: B

Rationale: 'But' is the conjunction in this sentence. A conjunction is a word that connects clauses or sentences. In this case, 'but' links two contrasting ideas: the little girl wanting a cookie and her decision not to take one. The other options are not conjunctions; 'little' is an adjective, 'take' is a verb, and 'the' is a definite article.
