1. Cells that line the inner or outer surfaces of organs or body cavities are often linked together by intimate physical connections. These connections are referred to as ______.

• A. Separate desmosomes
• B. Ronofilaments
• C. Tight junctions
• D. Fascia adherens

Correct answer: C

Rationale: The correct answer is C: Tight junctions. Tight junctions, also known as zonula occludens, are the intimate physical connections between cells that line the inner or outer surfaces of organs or body cavities. These junctions form a virtually impermeable barrier to fluid, creating a tight seal between the cells. This helps in maintaining the integrity and function of the tissue as well as regulating the movement of substances across the cell layer. Choice A, Separate desmosomes, are cell structures that provide strong adhesion between cells but do not create a barrier to fluid. Choice B, Ronofilaments, is not a term used to describe the connections between cells. Choice D, Fascia adherens, are another type of cell junction involved in cell adhesion, but they are different from tight junctions in terms of their structure and function.

2. Select the phrase that makes the following sentence grammatically correct: I hope that my parents ___________ if I am able to graduate early.

• A. are delighted
• B. were delighted
• C. will be delighted
• D. will have been delighted

Correct answer: C

Rationale: The correct answer is C: 'will be delighted.' In this context, the sentence is expressing a future possibility of graduating early, so the phrase 'will be delighted' in the future tense is the most appropriate choice to match the context. Choices A, B, and D are incorrect because they do not convey the future tense needed in this sentence. Choice A ('are delighted') is in the present tense, choice B ('were delighted') is in the past tense, and choice D ('will have been delighted') uses a more complex future perfect tense which is not necessary in this context.

3. What does it mean if something is distended?

• A. Shrunken
• B. Swollen
• C. Narrow
• D. Flattened

Correct answer: B

Rationale: When something is described as distended, it means that it is swollen or expanded, not shrunken, narrow, or flattened. In a medical context, distention often refers to an abnormal swelling or enlargement of an organ or structure. 'Shrunken' is incorrect as it means reduced in size, 'narrow' is incorrect as it means not wide, and 'flattened' is incorrect as it means pressed or squeezed flat.

4. Select the sentence that is grammatically correct.

• A. Dr. Chu told me and her to take a break for lunch.
• B. Dr. Chu told her and me to take a break for lunch.
• C. Dr. Chu told her and me to take a break for lunch.
• D. Dr. Chu told she and I to take a break for lunch.

Correct answer: B

Rationale: The correct pronouns to use as objects of the verb 'told' are 'her' and 'me.' Therefore, the grammatically correct sentence is: 'Dr. Chu told her and me to take a break for lunch.' 'Her' is used as the object form of 'she,' and 'me' is the object form of 'I' in this context. Choice A is incorrect because 'me' should come before 'her' in the sentence. Choice C is a duplicate of the correct answer. Choice D is incorrect because 'she' should be 'her' and 'I' should be 'me' to function as objects in the sentence.

5. The mail carrier's job is to put the _____ in every mailbox on the block.

• A. letter
• B. envelope
• C. package
• D. documents

Correct answer: B

Rationale: The correct answer is B: 'envelope.' The mail carrier typically delivers envelopes containing mail to every mailbox on the block. Envelopes are commonly used to protect and contain letters, making them the most suitable choice in this context. Choices A, C, and D are incorrect because while the mail carrier may deliver letters, packages, or documents, the most common item placed in mailboxes is an envelope containing mail.
