1. Cartilage is a flexible connective tissue found in the:

• A. Center of long bones
• B. Joints between bones
• C. Muscle tissue
• D. Walls of blood vessels

Correct answer: B

Rationale: Cartilage is a flexible connective tissue found in the joints between bones. It provides cushioning and support for the bones, allowing smooth movement and reducing friction between them. Cartilage acts as a shock absorber and helps maintain the structural integrity of the joints. Choices A, C, and D are incorrect because cartilage is not typically found in the center of long bones, muscle tissue, or the walls of blood vessels. Cartilage primarily functions in providing structural support and flexibility in joints.

2. Juan wishes to compare the percentages of time he spends on different tasks during the workday. Which of the following representations is the most appropriate choice for displaying the data?

• A. Line plot
• B. Bar graph
• C. Line graph
• D. Pie chart

Correct answer: D

Rationale: A pie chart is the most appropriate choice for displaying the percentages of time spent on different tasks during the workday because it visually represents parts of a whole. In this case, each task's percentage represents a part of the entire workday, making a pie chart an ideal way to compare these percentages. Line plots, bar graphs, and line graphs are not suitable for showing percentages of a whole; they are more commonly used for tracking trends, comparing values, or showing relationships between variables but do not efficiently represent parts of a whole like a pie chart does.

3. The control center of the cell, containing genetic information (DNA), is the:

• A. Golgi apparatus
• B. Ribosome
• C. Nucleus
• D. Endoplasmic reticulum

Correct answer: C

Rationale: The correct answer is C, the nucleus. The nucleus is the control center of the cell and houses the genetic information in the form of DNA. The Golgi apparatus (choice A) is responsible for packaging and processing proteins, the ribosome (choice B) is involved in protein synthesis, and the endoplasmic reticulum (choice D) is involved in protein and lipid synthesis. Therefore, choices A, B, and D are not the correct answers as they do not house the genetic information or serve as the control center of the cell.

4. What is the process by which muscle tissue wastes away due to disuse or lack of nutrients?

• A. Hypertrophy
• B. Atrophy
• C. Fibrosis
• D. Rigor mortis

Correct answer: B

Rationale: Atrophy is the correct term for the process by which muscle tissue wastes away due to disuse or lack of nutrients. It is essential to differentiate atrophy from hypertrophy, which is the increase in muscle size due to exercise or strength training. Fibrosis involves the formation of excess fibrous connective tissue, which is distinct from muscle wasting. Rigor mortis, on the other hand, is the stiffening of muscles that occurs after death and is not related to muscle wasting during life.

5. Which example uses quotations correctly?

• A. "I'm not going to spoil my appetite," said Philip, as he pushed the plate of cookies away.
• B. "I'm not going to spoil my appetite," said Philip, as he pushed the plate of cookies away.
• C. "I'm not going to spoil my appetite," said Philip, "as he pushed the plate of cookies away."
• D. "I'm not going to spoil my appetite," said Philip, as he pushed the plate of cookies away.

Correct answer: D

Rationale: Choice D is the correct answer as it uses quotation marks to properly set off the spoken words. In this sentence, the spoken words by Philip are enclosed within double quotation marks and correctly punctuated with a comma before the attribution 'said Philip.' Choices A, B, and C contain errors such as missing commas, incorrect placement of quotation marks, or incorrect punctuation within the quoted speech. For example, in Choice A, there should be a comma after 'appetite' within the quotation. In Choice B, the comma should be placed inside the quotation marks. Choice C incorrectly places the attribution 'said Philip' within the quotation of spoken words, which is not the standard practice.
